This is the code base for the paper [DeeBERT: Dynamic Early Exiting for Accelerating BERT Inference](https://www.aclweb.org/anthology/2020.acl-main.204/), modified from its [original code base](https://github.com/castorini/deebert).
The original code base also has information for downloading sample models that we have trained in advance.
## Usage
There are three scripts in the folder which can be run directly.
In each script, there are several things to modify before running:
* `PATH_TO_DATA`: path to the GLUE dataset.
* `--output_dir`: path for saving fine-tuned models. Default: `./saved_models`.
* `--plot_data_dir`: path for saving evaluation results. Default: `./results`. Results are printed to stdout and also saved to `npy` files in this directory to facilitate plotting figures and further analyses.
* `MODEL_TYPE`: bert or roberta
* `MODEL_SIZE`: base or large
* `DATASET`: SST-2, MRPC, RTE, QNLI, QQP, or MNLI
#### train_deebert.sh
This is for fine-tuning DeeBERT models.
#### eval_deebert.sh
This is for evaluating each exit layer for fine-tuned DeeBERT models.
#### entropy_eval.sh
This is for evaluating fine-tuned DeeBERT models, given a number of different early exit entropy thresholds.

mavonic_private_repos/transformers/examples/research_projects | mavonic_private_repos/transformers/examples/research_projects/jax-projects/HOW_TO_PROPOSE_PROJECT.md | # How to propose a Flax/JAX + Transformers project
Great that you've opened this document!
While we at 🤗 are proposing a couple of projects, we strongly
believe that the community can come up with much more **creative**, **fun**, and
**impactful** projects on their own. This being said, we are really looking forward
to seeing your project proposal!
## What a project should be about
The proposed project should fall into the machine learning fields of **Natural Language Processing (NLP)** and/or **Computer Vision (CV)** (possibly also **Speech Recognition (ASR)** depending on whether Speech Recognition models are available in Flax in due time) and aim at solving a specific task.
Possible tasks can belong to:
* text classification
* text generation
* image recognition
* image processing
* image captioning
* audio classification
* and other tasks you can think of!
The clearer a task is defined, the better your project proposal is.
*E.g.* "Using a T5 model to learn grammar correction in French" or "Adapting a pre-trained CLIP model for zero-shot image classification in Spanish" are **well-defined and clear** project proposals, while something like "Train a language model" or "Image classification" are **too vague**.
There is no limit to your creativity as long as the project is feasible and ethical.
The more creative & specific your project proposal, the more interesting it will be,
and the more likely will you find motivated team members to work on your project!
To get an idea of how to formulate your project proposals, you can browse through
existing project proposals on the [forum](https://discuss.huggingface.co/c/flax-jax-projects/22).
## How to submit a project proposal
First, you should make sure that you are [logged in](https://huggingface.co/login?sso=bm9uY2U9OTRlNjZjZmZhYjMwMmJmMWMyYjc5MmFiMTMyMzY5ODYmcmV0dXJuX3Nzb191cmw9aHR0cHMlM0ElMkYlMkZkaXNjdXNzLmh1Z2dpbmdmYWNlLmNvJTJGc2Vzc2lvbiUyRnNzb19sb2dpbg%3D%3D&sig=429ad8924bcb33c40f9823027ea749abb55d393f4f58924f36a2dba3ab0a48da) with your Hugging Face account on the forum.
Second, make sure that your project idea doesn't already exist by checking [existing projects](https://discuss.huggingface.co/c/flax-jax-projects/22).
If your project already exists - great! This means that you can comment and improve
the existing idea and join the project to form a team! If your project idea already
exists for a different language, feel free to submit the same project idea, just in
a different language.
Third, having ensured that your project doesn't exist, click on the *"New Topic"*
button on the [Flax/JAX Projects Forum category](https://discuss.huggingface.co/c/flax-jax-projects/22) to create a new project proposal.
Fourth, make sure that your project proposal includes the following information:
1. *A clear description of the project*
2. *In which language should the project be conducted?* English, German, Chinese, ...? It can also be a multi-lingual project
3. *Which model should be used?* If you want to adapt an existing model, you can add the link to one of the 4000 available checkpoints in JAX [here](https://huggingface.co/models?filter=jax) If you want to train a model from scratch, you can simply state the model architecture to be used, *e.g.* BERT, CLIP, etc. You can also base your project on a model that is not part of transformers. For an overview of libraries based on JAX, you can take a look at [awesome-jax](https://github.com/n2cholas/awesome-jax#awesome-jax-). **Note** that for a project that is not based on Transformers it will be more difficult for the 🤗 team to help you. Also have a look at the section [Quickstart Flax & Jax in Transformers](https://github.com/huggingface/transformers/tree/main/examples/research_projects/jax-projects#quickstart-flax-and-jax-in-transformers) to see what model architectures are currently supported in 🤗 Transformers.
4. *What data should be used?* It is important to state at least what kind of data you would like to use. Ideally, you can already point to publicly available data or a dataset in the 🤗 Datasets library.
5. *Are similar training scripts available in Flax/JAX?* It would be important to find similar training scripts that already exist in Flax/JAX. *E.g.* if you are working on a Seq-to-Seq task, you can make use of the [`run_summarization_flax.py`](https://github.com/huggingface/transformers/blob/main/examples/flax/summarization/run_summarization_flax.py) script which is very similar to any seq2seq training. Also have a look at the section [Quickstart Flax & Jax in Transformers](https://github.com/huggingface/transformers/tree/main/examples/research_projects/jax-projects#quickstart-flax-and-jax-in-transformers) to see what training scripts are currently supported in 🤗 Transformers.
6. *(Optionally) What are possible challenges?* List possible difficulties with your project. *E.g.* If you know that training convergence usually takes a lot of time, it is worth stating this here!
7. *(Optionally) What is the desired project outcome?* - How would you like to demo your project? One could *e.g.* create a Streamlit application.
8. *(Optionally) Links to read upon* - Can you provide any links that would help the reader to better understand your project idea?
Feel free to copy-paste the following format for your project proposal and fill out the respective sections:
```
# <FILL ME: Name of project>
<FILL ME: A clear description of the project>
## 2. Language
The model will be trained in <FILL ME: which language?>.
## 3. Model
<FILL ME: 3. Which model should be used?>
## 4. Datasets
<FILL ME: 4. Which data should be used?>
Possible links to publicly available datasets include:
- <FILL ME: Link 1 to dataset>
- <FILL ME: Link 2 to dataset>
- <FILL ME: Link 3 to dataset>
## 5. Training scripts
<FILL ME: 5. Are there publicly available training scripts that can be used/tweaked for the project?>
We can make use of <FILL ME: link to training script> to train the model.>
## 6. (Optional) Challenges
<(Optionally) FILL ME: 6. What are possible challenges?>
## 7. (Optional) Desired project outcome
<(Optionally) FILL ME: 7. What is the desired project outcome? A demo?>
## 8. (Optional) Reads
The following links can be useful to better understand the project and
what has previously been done.
- <FILL ME: Link 1 to read>
- <FILL ME: Link 2 to read>
- <FILL ME: Link 3 to read>
```
To see how a proposed project looks like, please have a look at submitted project
proposals [here](https://discuss.huggingface.co/c/flax-jax-projects/22).
## Will my project proposal be selected?
Having submitted a project proposal, you can now promote your idea in the Slack channel `#flax-jax-community-week` to try to convince other participants to join your project!
Once other people have joined your project, one of the organizers (`@Suzana, @valhalla, @osanseviero, @patrickvonplaten`) will officially create a team for your project and add your project to [this google sheet](https://docs.google.com/spreadsheets/d/1GpHebL7qrwJOc9olTpIPgjf8vOS0jNb6zR_B8x_Jtik/edit?usp=sharing).

mavonic_private_repos/transformers/examples/research_projects | mavonic_private_repos/transformers/examples/research_projects/jax-projects/README.md | # Flax/JAX community week 🤗
Welcome to the Flax/JAX community week! The goal of this week is to make compute-intensive NLP and CV projects (like pre-training BERT, GPT2, CLIP, ViT)
practicable for a wider audience of engineers and researchers.
To do so, we will try to teach **you** how to effectively use JAX/Flax on TPU and help you to complete a fun NLP and/or CV project in JAX/Flax during the community week.
Free access to a TPUv3-8 will kindly be provided by the Google Cloud team!
In this document, we list all the important information that you will need during the Flax/JAX community week.
Don't forget to sign up [here](https://forms.gle/tVGPhjKXyEsSgUcs8)!

## Organization
Participants can propose ideas for an interesting NLP and/or CV project. Teams of 3 to 5 will then be formed around the most promising and interesting projects. Make sure to read through the [Projects](#projects) section on how to propose projects, comment on other participants' project ideas, and create a team.
To help each team successfully finish their project, we have organized talks by leading scientists and engineers from Google, Hugging Face, and the open-source NLP & CV community. The talks will take place before the community week from June 30th to July 2nd. Make sure to attend the talks to get the most out of your participation! Check out the [Talks](#talks) section to get an overview of the talks, including the speaker and the time of the talk.
Each team is then given **free access to a TPUv3-8 VM** from July 7th to July 14th. In addition, we will provide training examples in JAX/Flax for a variety of NLP and Vision models to kick-start your project. During the week, we'll make sure to answer any questions you might have about JAX/Flax and Transformers and help each team as much as possible to complete their project!
At the end of the community week, each team should submit a demo of their project. All demonstrations will be evaluated by a jury and the top-3 demos will be awarded a prize. Check out the [How to submit a demo](#how-to-submit-a-demo) section for more information and suggestions on how to submit your project.

## Communication
All important communication will take place in an internal Slack channel, called `#flax-jax-community-week`.
Important announcements of the Hugging Face, Flax/JAX, and Google Cloud team will be posted there.
Such announcements include general information about the community week (Dates, Rules, ...), release of relevant training scripts (Flax/JAX example scripts for NLP and Vision), release of other important documents (How to access the TPU), etc.
The Slack channel will also be the central place for participants to post about their results, share their learning experiences, ask questions, etc.
For issues with Flax/JAX, Transformers, Datasets or for questions that are specific to your project we would be **very happy** if you could use the following public repositories and forums:
- Flax: [Issues](https://github.com/google/flax/issues), [Questions](https://github.com/google/flax/discussions)
- JAX: [Issues](https://github.com/google/jax/issues), [Questions](https://github.com/google/jax/discussions)
- 🤗 Transformers: [Issues](https://github.com/huggingface/transformers/issues), [Questions](https://discuss.huggingface.co/c/transformers/9)
- 🤗 Datasets: [Issues](https://github.com/huggingface/datasets/issues), [Questions](https://discuss.huggingface.co/c/datasets/10)
- Project specific questions: [Forum](https://discuss.huggingface.co/c/flax-jax-projects/22)
- TPU related questions: [TODO]()
Please do **not** post the complete issue/project-specific question in the Slack channel, but instead a link to your issue/question that we will try to answer as soon as possible.
This way, we make sure that the everybody in the community can benefit from your questions - even after the community week - and that the same question is not answered twice.
To be invited to the Slack channel, please make sure you have signed up [on the Google form](https://forms.gle/tVGPhjKXyEsSgUcs8).
**Note**: If you have signed up on the google form, but you are not in the Slack channel, please leave a message on [(TODO) the official forum announcement]( ) and ping `@Suzana` and `@patrickvonplaten`.
## Projects
During the first week after the community week announcement, **23.06. - 30.06.**, teams will be formed around the most promising and interesting project ideas. Each team can consist of 2 to 10 participants. Projects can be accessed [here](https://discuss.huggingface.co/c/flax-jax-projects/22).
All officially defined projects can be seen [here](https://docs.google.com/spreadsheets/d/1GpHebL7qrwJOc9olTpIPgjf8vOS0jNb6zR_B8x_Jtik/edit?usp=sharing).
### How to propose a project
Some default project ideas are given by the organizers. **However, we strongly encourage participants to submit their own project ideas!**
Check out the [HOW_TO_PROPOSE_PROJECT.md](https://github.com/huggingface/transformers/tree/main/examples/research_projects/jax-projects/HOW_TO_PROPOSE_PROJECT.md) for more information on how to propose a new project.
### How to form a team around a project
You can check out all existing projects ideas on the forum under [Flax/JAX projects category](https://discuss.huggingface.co/c/flax-jax-projects/22).
Make sure to quickly check out each project idea and leave a ❤️ if you like an idea.
Feel free to leave comments, suggestions for improvement, or questions about more details directly on the discussion thread.
If you have found the project that you ❤️ the most, leave a message "I would like to join this project" on the discussion thread.
We strongly advise you to also shortly state who you are, which time zone you are in and why you would like to work on this project, how you can contribute to the project and what your vision is for the project.
For projects that see a lot of interest and for which enough participants have expressed interest in joining, an official team will be created by the organizers.
One of the organizers (`@Suzana`, `@valhalla`, `@osanseviero`, `@patrickvonplaten`) will leave a message "For this project the team: `<team_name>`, `<team_members>` , is officially created" on the thread and note down the teams on [this google sheet](https://docs.google.com/spreadsheets/d/1GpHebL7qrwJOc9olTpIPgjf8vOS0jNb6zR_B8x_Jtik/edit?usp=sharing).
Once created, the team can start refining their project:
- What is the goal of the project? *E.g.*, Present a language model that writes poetry in Russian.
- What model will we use? *E.g.*, FlaxGPT2
- What data will we use? *E.g.* Russian dataset of OSCAR & publicly available book on poetry
- Should we use a pre-trained model or train a model from scratch? E.g. Train a model from scratch
- What training scripts do we need? *E.g.* `transformers/examples/flax/run_clm_flax.py` can be used
- What kind of demo would we like to present? E.g. Text-generation API of the 🤗 Hub in combination with a Streamlit demo that lets the user generate a poem of a given length
- How will the work be divided? *E.g.* Team member 1 works on data preprocessing, Team member 2 works on adapting the Flax script, ...
We highly recommend that each team discusses all relevant ideas for their project directly on the forum thread.
This way valuable learning experiences are shared and accessible by the whole community in the future.
Additionally, the organizers, other participants, or anybody in the community really can read through your discussions and leave comments/tips for improvement. Obviously, you can also create private chats, ... to discuss more sensitive topics, etc.
**Important**:
- For project ideas that see a lot of interest, we are more than happy to create more than one team.
- Participants are welcome to join multiple teams, even though we encourage them to only work on a single project.
- Under special circumstances, participants can change/create new teams. Please note that we would like to keep this the exception. If however, you would like to change/leave existing teams, please leave a post on the project's thread where you ping the corresponding organizer that created the group.
- It is often easy to propose/join a project that is done in your native language. Feel free to reach out to existing [language-specific groups](https://discuss.huggingface.co/c/languages-at-hugging-face/15) to look for community members that might be interested in joining your project.
## Tips on how to organize the project
This section gives you some tips on how to most efficiently & effectively
work as a team to achieve your goal. It is by no means a strict recipe to follow,
but rather a collection of tips from the 🤗 team.
Once your team is defined, you can start working on the project as soon as possible.
### Communication
At first, it is always useful to get to know each other and to set up a means of communication.
While we recommend that all technical aspects of work can be discussed directly on the [forum](https://discuss.huggingface.co/c/flax-jax-projects/22) under your project thread,
it can be very helpful to have a more direct way of communicating, *e.g.* in a channel.
For this we have created a discord that you can access [here](https://discord.com/channels/858019234139602994/858019234139602997).
This discord will not be managed by anybody and is just there so that you can communicate more effectively with your team members.
Feel free to create a new channel for you and your team where you can discuss everything. If you and your team have already set up other ways of communicating, it is absolutely not required to make use of the discord. However, we do recommend each team to set up some kind
of channel or group for quick discussions.
### Project definition
In the very beginning, you should make sure your project is well-defined and that
everybody in the team understands the goal of the project and the work that needs to be
done in order to achieve the goal. A well-defined project:
- has defined the task on which the model will be trained
- has defined the model that will be trained
- has defined the datasets that will be used for training
- has defined the type of training scripts that need to be written
- has defined the desired outcome of the project
- has defined the workflows
By "has defined" we don't meant that the corresponding code already has to be written and ready
to be used, but that everybody in team is on the same page on what type of model, data and training script should be used.
To give an example, a well-defined project would be the following:
- task: summarization
- model: [google-t5/t5-small](https://huggingface.co/google-t5/t5-small)
- dataset: [CNN/Daily mail](https://huggingface.co/datasets/cnn_dailymail)
- training script: [run_summarization_flax.py](https://github.com/huggingface/transformers/blob/main/examples/flax/summarization/run_summarization_flax.py)
- outcome: t5 model that can summarize news
- work flow: adapt `run_summarization_flax.py` to work with `google-t5/t5-small`.
This example is a very easy and not the most interesting project since a `google-t5/t5-small`
summarization model exists already for CNN/Daily mail and pretty much no code has to be
written.
A well-defined project does not need to have the dataset be part of
the `datasets` library and the training script already be pre-written, however it should
be clear how the desired dataset can be accessed and how the training script can be
written.
It is also important to have a clear plan regarding the workflow. Usually, the
data processing is done in a first step. Once the data is in a format that the model can
work with, the training script can be written, etc. These steps should be more detailed
once the team has a clearly defined project. It can be helpful to set deadlines for each step.
### Workload division
To effectively work as a team, it is crucial to divide the workload among everybody.
Some team members will be more motivated and experienced than others and
some team members simply want to participate to learn more and cannot contribute that
much to the team. This is totally fine! One cannot expect everybody in the team to have the same level of experience and time/motivation during the community week.
As a conclusion, being honest about one's expected involvement is crucial so that
the workload can be divided accordingly. If someone doesn't think her/his tasks are feasible - let
the team know early on so that someone else can take care of it!
It is recommended that the motivated and experienced team members take the lead in dividing the work and are ready to take over the tasks of another team member if necessary.
The workload can often be divided according to:
- data preprocessing (load the data and preprocess data in the correct format)
- data tokenization / data collator (process data samples into tokens or images)
- model configuration (writing the code that defines the model)
- model forward pass (make sure input / output work correctly)
- loss function (define the loss function)
- putting the pieces together in a training script
Many of the steps above require other steps to be finished, so it often makes sense
to use dummy data in the expected format to start, *e.g.*, with the model forward pass
before the data preprocessing is done.
### Expectations
It is also very important to stay realistic with the scope of your project. Each team
has access to a TPUv3-8 for only *ca.* 10 days, so it's important to keep the scope of
the project reasonable. While we do want each team to work on interesting projects, each
team should make sure that the project goals can be achieved within the provided compute
time on TPU. For instance, pretraining a 11 billion parameters T5 model is not really a realistic
task with just 10 days of TPUv3-8 compute.
Also, it might be difficult to finish a project where the whole modeling, dataset and training code has to be written from scratch.
Having defined your project, feel free to reach out on Slack or the forum for feedback from the organizers. We can surely give you our opinion on whether the project is feasible and what can be done to improve it.
the project is feasible.
### Other tips
Here is a collection of some more tips:
- We strongly recommend to work as publicly and collaboratively as possible during the week so that other teams
and the organizers can best help you. This includes publishing important discussions on
the forum and making use of the [🤗 hub](http://huggingface.co/) to have a version
control for your models and training logs.
- When debugging, it is important that the debugging cycle is kept as short as possible to
be able to effectively debug. *E.g.* if there is a problem with your training script,
you should run it with just a couple of hundreds of examples and not the whole dataset script. This can be done by either making use of [datasets streaming](https://huggingface.co/docs/datasets/master/dataset_streaming?highlight=streaming) or by selecting just the first
X number of data samples after loading:
```python
datasets["train"] = datasets["train"].select(range(1000))
```
- Ask for help. If you are stuck, use the public Slack channel or the [forum](https://discuss.huggingface.co/c/flax-jax-projects/22) to ask for help.
## How to install relevant libraries
In the following we will explain how to install all relevant libraries on your local computer and on TPU VM.
It is recommended to install all relevant libraries both on your local machine
and on the TPU virtual machine. This way, quick prototyping and testing can be done on
your local machine and the actual training can be done on the TPU VM.
### Local computer
The following libraries are required to train a JAX/Flax model with 🤗 Transformers and 🤗 Datasets:
- [JAX](https://github.com/google/jax/)
- [Flax](https://github.com/google/flax)
- [Optax](https://github.com/deepmind/optax)
- [Transformers](https://github.com/huggingface/transformers)
- [Datasets](https://github.com/huggingface/datasets)
You should install the above libraries in a [virtual environment](https://docs.python.org/3/library/venv.html).
If you're unfamiliar with Python virtual environments, check out the [user guide](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/). Create a virtual environment with the version of Python you're going
to use and activate it.
You should be able to run the command:
```bash
python3 -m venv <your-venv-name>
```
You can activate your venv by running
```bash
source ~/<your-venv-name>/bin/activate
```
We strongly recommend to make use of the provided JAX/Flax examples scripts in [transformers/examples/flax](https://github.com/huggingface/transformers/tree/main/examples/flax) even if you want to train a JAX/Flax model of another github repository that is not integrated into 🤗 Transformers.
In all likelihood, you will need to adapt one of the example scripts, so we recommend forking and cloning the 🤗 Transformers repository as follows.
Doing so will allow you to share your fork of the Transformers library with your team members so that the team effectively works on the same code base. It will also automatically install the newest versions of `flax`, `jax` and `optax`.
1. Fork the [repository](https://github.com/huggingface/transformers) by
clicking on the 'Fork' button on the repository's page. This creates a copy of the code
under your GitHub user account.
2. Clone your fork to your local disk, and add the base repository as a remote:
```bash
$ git clone https://github.com/<your Github handle>/transformers.git
$ cd transformers
$ git remote add upstream https://github.com/huggingface/transformers.git
```
3. Create a new branch to hold your development changes. This is especially useful to share code changes with your team:
```bash
$ git checkout -b a-descriptive-name-for-my-project
```
4. Set up a flax environment by running the following command in a virtual environment:
```bash
$ pip install -e ".[flax]"
```
(If transformers was already installed in the virtual environment, remove
it with `pip uninstall transformers` before reinstalling it in editable
mode with the `-e` flag.)
If you have already cloned that repo, you might need to `git pull` to get the most recent changes in the `datasets`
library.
Running this command will automatically install `flax`, `jax` and `optax`.
Next, you should also install the 🤗 Datasets library. We strongly recommend installing the
library from source to profit from the most current additions during the community week.
Simply run the following steps:
```bash
$ cd ~/
$ git clone https://github.com/huggingface/datasets.git
$ cd datasets
$ pip install -e ".[streaming]"
```
If you plan on contributing a specific dataset during
the community week, please fork the datasets repository and follow the instructions
[here](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-create-a-pull-request).
To verify that all libraries are correctly installed, you can run the following command.
It assumes that both `transformers` and `datasets` were installed from main - otherwise
datasets streaming will not work correctly.
```python
from transformers import FlaxRobertaModel, RobertaTokenizerFast
from datasets import load_dataset
import jax
dataset = load_dataset('oscar', "unshuffled_deduplicated_en", split='train', streaming=True)
dummy_input = next(iter(dataset))["text"]
tokenizer = RobertaTokenizerFast.from_pretrained("FacebookAI/roberta-base")
input_ids = tokenizer(dummy_input, return_tensors="np").input_ids[:, :10]
model = FlaxRobertaModel.from_pretrained("julien-c/dummy-unknown")
# run a forward pass, should return an object `FlaxBaseModelOutputWithPooling`
model(input_ids)
```
### TPU VM
**VERY IMPORTANT** - Only one process can access the TPU cores at a time. This means that if multiple team members
are trying to connect to the TPU cores errors, such as:
```
libtpu.so already in used by another process. Not attempting to load libtpu.so in this process.
```
are thrown. As a conclusion, we recommend every team member to create her/his own virtual environment, but only one
person should run the heavy training processes. Also, please take turns when setting up the TPUv3-8 so that everybody
can verify that JAX is correctly installed.
The following libraries are required to train a JAX/Flax model with 🤗 Transformers and 🤗 Datasets on TPU VM:
- [JAX](https://github.com/google/jax/)
- [Flax](https://github.com/google/flax)
- [Optax](https://github.com/deepmind/optax)
- [Transformers](https://github.com/huggingface/transformers)
- [Datasets](https://github.com/huggingface/datasets)
You should install the above libraries in a [virtual environment](https://docs.python.org/3/library/venv.html).
If you're unfamiliar with Python virtual environments, check out the [user guide](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/). Create a virtual environment with the version of Python you're going
to use and activate it.
You should be able to run the command:
```bash
python3 -m venv <your-venv-name>
```
If this doesn't work, you first might to have install `python3-venv`. You can do this as follows:
```bash
sudo apt-get install python3-venv
```
You can activate your venv by running
```bash
source ~/<your-venv-name>/bin/activate
```
Next you should install JAX's TPU version on TPU by running the following command:
```bash
$ pip install requests
```
and then:

Jax should have been installed correctly nevertheless.
To verify that JAX was correctly installed, you can run the following command:
```python
import jax
jax.device_count()
```
This should display the number of TPU cores, which should be 8 on a TPUv3-8 VM.
We strongly recommend to make use of the provided JAX/Flax examples scripts in [transformers/examples/flax](https://github.com/huggingface/transformers/tree/main/examples/flax) even if you want to train a JAX/Flax model of another github repository that is not integrated into 🤗 Transformers.
In all likelihood, you will need to adapt one of the example scripts, so we recommend forking and cloning the 🤗 Transformers repository as follows.
Doing so will allow you to share your fork of the Transformers library with your team members so that the team effectively works on the same code base. It will also automatically install the newest versions of `flax`, `jax` and `optax`.
1. Fork the [repository](https://github.com/huggingface/transformers) by
clicking on the 'Fork' button on the repository's page. This creates a copy of the code
under your GitHub user account.
2. Clone your fork to your local disk, and add the base repository as a remote:
```bash
$ git clone https://github.com/<your Github handle>/transformers.git
$ cd transformers
$ git remote add upstream https://github.com/huggingface/transformers.git
```
3. Create a new branch to hold your development changes. This is especially useful to share code changes with your team:
```bash
$ git checkout -b a-descriptive-name-for-my-project
```
4. Set up a flax environment by running the following command in a virtual environment:
```bash
$ pip install -e ".[flax]"
```
(If transformers was already installed in the virtual environment, remove
it with `pip uninstall transformers` before reinstalling it in editable
mode with the `-e` flag.)
If you have already cloned that repo, you might need to `git pull` to get the most recent changes in the `datasets`
library.
Running this command will automatically install `flax`, `jax` and `optax`.
Next, you should also install the 🤗 Datasets library. We strongly recommend installing the
library from source to profit from the most current additions during the community week.
Simply run the following steps:
```bash
$ cd ~/
$ git clone https://github.com/huggingface/datasets.git
$ cd datasets
$ pip install -e ".[streaming]"
```
If you plan on contributing a specific dataset during
the community week, please fork the datasets repository and follow the instructions
[here](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-create-a-pull-request).
To verify that all libraries are correctly installed, you can run the following command.
It assumes that both `transformers` and `datasets` were installed from main - otherwise
datasets streaming will not work correctly.
```python
from transformers import FlaxRobertaModel, RobertaTokenizerFast
from datasets import load_dataset
import jax
dataset = load_dataset('oscar', "unshuffled_deduplicated_en", split='train', streaming=True)
dummy_input = next(iter(dataset))["text"]
tokenizer = RobertaTokenizerFast.from_pretrained("FacebookAI/roberta-base")
input_ids = tokenizer(dummy_input, return_tensors="np").input_ids[:, :10]
model = FlaxRobertaModel.from_pretrained("julien-c/dummy-unknown")
# run a forward pass, should return an object `FlaxBaseModelOutputWithPooling`
model(input_ids)
```
## Quickstart flax and jax
[JAX](https://jax.readthedocs.io/en/latest/index.html) is Autograd and XLA, brought together for high-performance numerical computing and machine learning research. It provides composable transformations of Python+NumPy programs: differentiate, vectorize, parallelize, Just-In-Time compile to GPU/TPU, and more. A great place for getting started with JAX is the [JAX 101 Tutorial](https://jax.readthedocs.io/en/latest/jax-101/index.html).
[Flax](https://flax.readthedocs.io/en/latest/index.html) is a high-performance neural network library designed for flexibility built on top of JAX. It aims to provide users with full control of their training code and is carefully designed to work well with JAX transformations such as `grad` and `pmap` (see the [Flax philosophy](https://flax.readthedocs.io/en/latest/philosophy.html)). For an introduction to Flax see the [Flax Basics Colab](https://flax.readthedocs.io/en/latest/notebooks/flax_basics.html) or the list of curated [Flax examples](https://flax.readthedocs.io/en/latest/examples.html).

### **Flax design philosophy in Transformers**
This section will explain how Flax models are implemented in Transformers and how the design differs from PyTorch.
Let's first go over the difference between Flax and PyTorch.
In JAX, most transformations (notably `jax.jit`) require functions that are transformed to be stateless so that they have no side effects. This is because any such side-effects will only be executed once when the transformed function is run during compilation and all subsequent calls of the compiled function would re-use the same side-effects of the compiled run instead of the "actual" side-effects (see [Stateful Computations in JAX](https://jax.readthedocs.io/en/latest/jax-101/07-state.html)). As a consequence, Flax models, which are designed to work well with JAX transformations, are stateless. This means that when running a model in inference, both the inputs and the model weights are passed to the forward pass. In contrast, PyTorch model are very much stateful with the weights being stored within the model instance and the user just passing the inputs to the forward pass.
Let's illustrate the difference between stateful models in PyTorch and stateless models in Flax.
For simplicity, let's assume the language model consists simply of a single attention layer [`key_proj`, `value_proj`, `query_proj`] and a linear layer `logits_proj` to project the transformed word embeddings to the output logit vectors.
#### **Stateful models in PyTorch**
In PyTorch, the weights matrices would be stored as `torch.nn.Linear` objects alongside the model's config inside the model class `ModelPyTorch`:
```python
class ModelPyTorch:
def __init__(self, config):
self.config = config
self.key_proj = torch.nn.Linear(config)
self.value_proj = torch.nn.Linear(config)
self.query_proj = torch.nn.Linear(config)
self.logits_proj = torch.nn.Linear(config)
```
Instantiating an object `model_pytorch` of the class `ModelPyTorch` would actually allocate memory for the model weights and attach them to the attributes `self.key_proj`, `self.value_proj`, `self.query_proj`, and `self.logits.proj`. We could access the weights via:
```python
key_projection_matrix = model_pytorch.key_proj.weight.data
```
Visually, we would represent an object of `model_pytorch` therefore as follows:
Executing a forward pass then simply corresponds to passing the `input_ids` to the object `model_pytorch`:
```python
sequences = model_pytorch(input_ids)
```
In a more abstract way, this can be represented as passing the word embeddings to the model function to get the output logits:
This design is called **stateful** because the output logits, the `sequences`, can change even if the word embeddings, the `input_ids`, stay the same. Hence, the function's output does not only depend on its inputs, but also on its **state**, `[self.key_proj, self.value_proj, self.query_proj, self.logits_proj]`, which makes `model_pytorch` stateful.
#### **Stateless models in Flax/JAX**
Now, let's see how the mathematically equivalent model would be written in JAX/Flax. The model class `ModelFlax` would define the self-attention and logits projection weights as [**`flax.linen.Dense`**](https://flax.readthedocs.io/en/latest/_autosummary/flax.linen.Dense.html#flax.linen.Dense) objects:
```python
class ModelFlax:
def __init__(self, config):
self.config = config
self.key_proj = flax.linen.Dense(config)
self.value_proj = flax.linen.Dense(config)
self.query_proj = flax.linen.Dense(config)
self.logits_proj = flax.linen.Dense(config)
```
At first glance the linear layer class `flax.linen.Dense` looks very similar to PyTorch's `torch.nn.Linear` class. However, instantiating an object `model_flax` only defines the linear transformation functions and does **not** allocate memory to store the linear transformation weights. In a way, the attribute `self.key_proj` tell the instantiated object `model_flax` to perform a linear transformation on some input and force it to expect a weight, called `key_proj`, as an input.
This time we would illustrate the object `model_flax` without the weight matrices:
Accordingly, the forward pass requires both `input_ids` as well as a dictionary consisting of the model's weights (called `state` here) to compute the `sequences`:
To get the initial `state` we need to explicitly do a forward pass by passing a dummy input:
```python
state = model_flax.init(rng, dummy_input_ids)
```
and then we can do the forward pass.
```python
sequences = model_flax.apply(state, input_ids)
```
Visually, the forward pass would now be represented as passing all tensors required for the computation to the model's object:
This design is called **stateless** because the output logits, the `sequences`, **cannot** change if the word embeddings, the `input_ids`, stay the same. Hence, the function's output only depends on its inputs, being the `input_ids` and the `state` dictionary consisting of the weights **state**, `[key_proj, value_proj, query_proj, logits_proj]`.
Another term which is often used to describe the design difference between Flax/JAX and PyTorch is **immutable** vs **mutable**. A instantiated Flax model, `model_flax`, is **immutable** as a logical consequence of `model_flax`'s output being fully defined by its input: If calling `model_flax` could mutate `model_flax`, then calling `model_flax` twice with the same inputs could lead to different results which would violate the "*statelessness*" of Flax models.
#### **Flax models in Transformers**
Now let us see how this is handled in `Transformers.` If you have used a Flax model in Transformers already, you might wonder how come you don't always have to pass the parameters to the function of the forward pass. This is because the `FlaxPreTrainedModel` class abstracts it away.
It is designed this way so that the Flax models in Transformers will have a similar API to PyTorch and Tensorflow models.
The `FlaxPreTrainedModel` is an abstract class that holds a Flax module, handles weights initialization, and provides a simple interface for downloading and loading pre-trained weights i.e. the `save_pretrained` and `from_pretrained` methods. Each Flax model then defines its own subclass of `FlaxPreTrainedModel`; *e.g.* the BERT model has `FlaxBertPreTrainedModel`. Each such class provides two important methods, `init_weights` and `__call__`. Let's see what each of those methods do:
- The `init_weights` method takes the expected input shape and a [`PRNGKey`](https://jax.readthedocs.io/en/latest/_autosummary/jax.random.PRNGKey.html) (and any other arguments that are required to get initial weights) and calls `module.init` by passing it a random example to get the initial weights with the given `dtype` (for ex. `fp32` or `bf16` etc). This method is called when we create an instance of the model class, so the weights are already initialized when you create a model i.e., when you do
model = FlaxBertModel(config)
- The `__call__` method defines forward pass. It takes all necessary model inputs and parameters (and any other arguments required for the forward pass). The parameters are optional; when no parameters are passed, it uses the previously initialized or loaded parameters which can be accessed using `model.params`. It then calls the `module.apply` method, passing it the parameters and inputs to do the actual forward pass. So we can do a forward pass using
output = model(inputs, params=params)
Let's look at an example to see how this works. We will write a simple two-layer MLP model.
First, write a Flax module that will declare the layers and computation.
```python
import flax.linen as nn
import jax.numpy as jnp
class MLPModule(nn.Module):
config: MLPConfig
dtype: jnp.dtype = jnp.float32
def setup(self):
self.dense1 = nn.Dense(self.config.hidden_dim, dtype=self.dtype)
self.dense2 = nn.Desne(self.config.hidden_dim, dtype=self.dtype)
def __call__(self, inputs):
hidden_states = self.dense1(inputs)
hidden_states = nn.relu(hidden_states)
hidden_states = self.dense2(hidden_states)
return hidden_states
```
Now let's define the `FlaxPreTrainedModel` model class.
```python
from transformers.modeling_flax_utils import FlaxPreTrainedModel
class FlaxMLPPreTrainedModel(FlaxPreTrainedModel):
config_class = MLPConfig
base_model_prefix = "model"
module_class: nn.Module = None
def __init__(self, config: BertConfig, input_shape: Tuple = (1, 8), seed: int = 0, dtype: jnp.dtype = jnp.float32, **kwargs):
# initialize the flax module
module = self.module_class(config=config, dtype=dtype, **kwargs)
super().__init__(config, module, input_shape=input_shape, seed=seed, dtype=dtype)
def init_weights(self, rng, input_shape):
# init input tensors
inputs = jnp.zeros(input_shape, dtype="i4")
params_rng, dropout_rng = jax.random.split(rng)
rngs = {"params": params_rng, "dropout": dropout_rng}
params = self.module.init(rngs, inputs)["params"]
return params
def __call__(self, inputs, params: dict = None):
params = {"params": params or self.params}
outputs = self.module.apply(params, jnp.array(inputs))
return outputs
```
Now we can define our model class as follows.
```python
class FlaxMLPModel(FlaxMLPPreTrainedModel):
module_class = FlaxMLPModule
```
Now the `FlaxMLPModel` will have a similar interface as PyTorch or Tensorflow models and allows us to attach loaded or randomly initialized weights to the model instance.
So the important point to remember is that the `model` is not an instance of `nn.Module`; it's an abstract class, like a container that holds a Flax module, its parameters and provides convenient methods for initialization and forward pass. The key take-away here is that an instance of `FlaxMLPModel` is very much stateful now since it holds all the model parameters, whereas the underlying Flax module `FlaxMLPModule` is still stateless. Now to make `FlaxMLPModel` fully compliant with JAX transformations, it is always possible to pass the parameters to `FlaxMLPModel` as well to make it stateless and easier to work with during training. Feel free to take a look at the code to see how exactly this is implemented for ex. [`modeling_flax_bert.py`](https://github.com/huggingface/transformers/blob/main/src/transformers/models/bert/modeling_flax_bert.py#L536)
Another significant difference between Flax and PyTorch models is that, we can pass the `labels` directly to PyTorch's forward pass to compute the loss, whereas Flax models never accept `labels` as an input argument. In PyTorch, gradient backpropagation is performed by simply calling `.backward()` on the computed loss which makes it very handy for the user to be able to pass the `labels`. In Flax however, gradient backpropagation cannot be done by simply calling `.backward()` on the loss output, but the loss function itself has to be transformed by `jax.grad` or `jax.value_and_grad` to return the gradients of all parameters. This transformation cannot happen under-the-hood when one passes the `labels` to Flax's forward function, so that in Flax, we simply don't allow `labels` to be passed by design and force the user to implement the loss function oneself. As a conclusion, you will see that all training-related code is decoupled from the modeling code and always defined in the training scripts themselves.
### **How to use flax models and example scripts**
#### **How to do a forward pass**
Let's first see how to load, save and do inference with Flax models. As explained in the above section, all Flax models in Transformers have similar API to PyTorch models, so we can use the familiar `from_pretrained` and `save_pretrained` methods to load and save Flax models.
Let's use the base `FlaxRobertaModel` without any heads as an example.
```python
from transformers import FlaxRobertaModel, RobertaTokenizerFast
import jax
tokenizer = RobertaTokenizerFast.from_pretrained("FacebookAI/roberta-base")
inputs = tokenizer("JAX/Flax is amazing ", padding="max_length", max_length=128, return_tensors="np")
model = FlaxRobertaModel.from_pretrained("julien-c/dummy-unknown")
@jax.jit
def run_model(input_ids, attention_mask):
# run a forward pass, should return an object `FlaxBaseModelOutputWithPooling`
return model(input_ids, attention_mask)
outputs = run_model(**inputs)
```
We use `jax.jit` to compile the function to get maximum performance. Note that in the above example, we set `padding=max_length` to pad all examples to the same length. We do this because JAX's compiler has to recompile a function everytime its input shape changes - in a sense a compiled function is not only defined by its code but also by its input and output shape. It is usually much more effective to pad the input to be of a fixed static shape than having to recompile every the function multiple times.
#### **How to write a training loop**
Now let's see how we can write a simple training loop to train Flax models, we will use `FlaxGPT2ForCausalLM` as an example.
A training loop for Flax models typically consists of
- A loss function that takes the parameters and inputs, runs the forward pass and returns the loss.
- We then transform the loss function using `jax.grad` or `jax.value_and_grad` so that we get the gradients of all parameters.
- An optimizer to update the paramteres using the gradients returned by the transformed loss function.
- A train step function which combines the loss function and optimizer update, does the forward and backward pass and returns the updated parameters.
Lets see how that looks like in code:
First initialize our model
```python
import jax
import jax.numpy as jnp
from transformers import FlaxGPT2ForCausalLM
model = FlaxGPT2ForCausalLM(config)
```
As explained above we don't compute the loss inside the model, but rather in the task-specific training script.
For demonstration purposes, we write a pseudo training script for causal language modeling in the following.
```python
from flax.training.common_utils import onehot
def cross_entropy(logits, labels):
return -jnp.sum(labels * jax.nn.log_softmax(logits, axis=-1), axis=-1)
# define a function which will run the forward pass return loss
def compute_loss(params, input_ids, labels):
logits = model(input_ids, params=params, train=True)
num_classes = logits.shape[-1]
loss = cross_entropy(logits, onehot(labels, num_classes)).mean()
return loss
```
Now we transform the loss function with `jax.value_and_grad`.
```python
# transform the loss function to get the gradients
grad_fn = jax.value_and_grad(compute_loss)
```
We use the [optax](https://github.com/deepmind/optax) library to Initialize the optimizer.
```python
import optax
params = model.params
tx = optax.sgd(learning_rate=3e-3)
opt_state = tx.init(params)
```
Now we define a single training step which will do a forward and a backward pass.
```python
def _train_step(params, opt_state, input_ids, labels)
# do the forward pass and get the loss and gradients
loss, grads = grad_fn(params, input_ids, labels)
# use the gradients to update parameters
updates, opt_state = tx.update(grads, opt_state)
updated_params = optax.apply_updates(params, updates)
return updates_params, opt_state, loss
train_step = jax.jit(_train_step)
```
Finally, let's run our training loop.
```python
# train loop
for i in range(10):
params, opt_state, loss = train_step(params, opt_state, input_ids, labels)
```
Note how we always pass the `params` and `opt_state` to the `train_step` which then returns the updated `params` and `opt_state`. This is because of the staless nature of JAX/Flax models, all the state
like parameters, optimizer state is kept external.
We can now save the model with the trained parameters using
```python
model.save_pretrained("awesome-flax-model", params=params)
```
Note that, as JAX is backed by the [XLA](https://www.tensorflow.org/xla) compiler any JAX/Flax code can run on all `XLA` compliant device without code change!
That menas you could use the same training script on CPUs, GPUs, TPUs.
To know more about how to train the Flax models on different devices (GPU, multi-GPUs, TPUs) and use the example scripts, please look at the [examples README](https://github.com/huggingface/transformers/tree/main/examples/flax).

#### Sabrina J. Mielke, PhD student at The Johns Hopkins University & Part-time research intern at HuggingFace
- Talk: From stateful code to purified JAX: how to build your neural net framework
- Abstract: Moving from object-oriented (and stateful) PyTorch- or TF2-code with tape-based backprop to JAX isn't easy---and while running grad() on numpy-oneliners is cool and all, you do wonder... how do I build actual big neural nets? Libraries like flax, trax, or haiku make it easy---but how could you build machinery like that yourself?
- Speaker info: Sabrina is a PhD student at the Johns Hopkins University and a part-time research intern at HuggingFace, researching open-vocabulary language models for segmentation and tokenization. She has published and co-organized workshops and shared tasks on these topics as well as on morphology and typological analysis in ACL, NAACL, EMNLP, LREC, and AAAI. You can find her reminisce for a time when formal language theory played a bigger role in NLP on Twitter at @sjmielke.

#### Mostafa Dehghani, Research Scientist, Google Brain
- Talk: Long Range Arena: Benchmarking Efficient Transformers
- Abstract: Transformers do not scale very well to long sequence lengths largely because of quadratic self-attention complexity. In the recent months, a wide spectrum of efficient, fast Transformers have been proposed to tackle this problem, more often than not claiming superior or comparable model quality to vanilla Transformer models. So, we now need a well-established consensus on how to evaluate this class of models. Moreover, inconsistent benchmarking on a wide spectrum of tasks and datasets makes it difficult to assess relative model quality amongst many models. I'll talk about a systematic and unified benchmark, LRA, specifically focused on evaluating model quality under long-context scenarios. LRA is a suite of tasks consisting of sequences ranging from 1K to 16K tokens, encompassing a wide range of data types and modalities such as text, natural, synthetic images, and mathematical expressions requiring similarity, structural, and visual-spatial reasoning. We systematically evaluate ten well-established long-range Transformer models (Reformers, Linformers, Linear Transformers, Sinkhorn Transformers, Performers, Synthesizers, Sparse Transformers, and Longformers) on LRA. LRA paves the way towards better understanding this class of efficient Transformer models, facilitates more research in this direction, and presents new challenging tasks to tackle.

#### Rohan Anil, Senior Staff Software Engineer, Google Research, Brain Team
- Talk: Scalable Second Order Optimization for Deep Learning
- Abstract: Optimization in machine learning, both theoretical and applied, is presently dominated by first-order gradient methods such as stochastic gradient descent. Second-order optimization methods, that involve second derivatives and/or second order statistics of the data, are far less prevalent despite strong theoretical properties, due to their prohibitive computation, memory and communication costs. In an attempt to bridge this gap between theoretical and practical optimization, we present a scalable implementation of a second-order preconditioned method (concretely, a variant of full-matrix Adagrad), that along with several critical algorithmic and numerical improvements, provides significant convergence and wall-clock time improvements compared to conventional first-order methods on state-of-the-art deep models. Our novel design effectively utilizes the prevalent heterogeneous hardware architecture for training deep models, consisting of a multicore CPU coupled with multiple accelerator units. We demonstrate superior performance compared to state-of-the-art on very large learning tasks such as machine translation with Transformers, language modeling with BERT, click-through rate prediction on Criteo, and image classification on ImageNet with ResNet-50.
- Speaker info: Rohan Anil is a software engineer at Google Research, Mountain View. Lately, he has been working on scalable and practical optimization techniques for efficient training of neural networks in various regimes.

## How to use the hub for collaboration
In this section, we will explain how a team can use the 🤗 hub to collaborate on a project.
The 🤗 hub allows each team to create a repository with integrated git version control that
should be used for their project.
The advantages of using a repository on the 🤗 hub are:
- easy collaboration - each team member has write access to the model repository
- integrated git version control - code scripts as well as large model files are tracked using git version control
- easy sharing - the hub allows each team to easily share their work during and after the event
- integrated tensorboard functionality - uploaded tensorboard traces are automatically displayed on an integrated tensorboard tab
We highly recommend each team to make use of the 🤗 hub during the event.
To better understand how the repository and the hub in general functions, please take a look at the documentation and the videos [here](https://huggingface.co/docs/hub).
Now let's explain in more detail how a project can be created on the hub. Having an officially defined project on [this](https://docs.google.com/spreadsheets/d/1GpHebL7qrwJOc9olTpIPgjf8vOS0jNb6zR_B8x_Jtik/edit?usp=sharing) Google Sheet you should be part of [the Flax Community organization on the hub](https://huggingface.co/flax-community). All repositories should be created under this organization so that write access can be shared and everybody can easily access other participants'
work 🤗. Note that we are giving each team member access to all repositories created under [flax-community](https://huggingface.co/flax-community), but we encourage participants to only clone and edit repositories corresponding to one's teams. If you want to help other teams, please ask them before changing files in their repository! The integrated git version control keeps track of
all changes, so in case a file was deleted by mistake, it is trivial to re-create it.
Awesome! Now, let's first go over a simple example where most of the required we'll pre-train a RoBERTa model on a low-resource language. To begin with, we create a repository
under [the Flax Community organization on the hub](https://huggingface.co/flax-community) by logging in to the hub and going to [*"Add model"*](https://huggingface.co/new). By default
the username should be displayed under "*Owner*", which we want to change to *flax-community*. Next, we give our repository a fitting name for the project - here we'll just call it
*roberta-base-als* because we'll be pretraining a RoBERTa model on the super low-resource language *Alemannic* (`als`). We make sure that the model is a public repository and create it!
It should then be displayed on [the Flax Community organization on the hub](https://huggingface.co/flax-community).
Great, now we have a project directory with integrated git version control and a public model page, which we can access under [flax-community/roberta-base-als](https://huggingface.co/flax-community/roberta-base-als). Let's create a short README so that other participants know what this model is about. You can create the README.md directly on the model page as a markdown file.
Let's now make use of the repository for training.
We assume that the 🤗 Transformers library and [git-lfs](https://git-lfs.github.com/) are correctly installed on our machine or the TPU attributed to us.
If this is not the case, please refer to the [Installation guide](#how-to-install-relevant-libraries) and the official [git-lfs](https://git-lfs.github.com/) website.
At first we should log in:
```bash
$ huggingface-cli login
```
Next we can clone the repo:
```bash
$ git clone https://huggingface.co/flax-community/roberta-base-als
```
We have now cloned the model's repository and it should be under `roberta-base-als`. As you can see,
we have all the usual git functionalities in this repo - when adding a file, we can do `git add .`, `git commit -m "add file"` and `git push`
as usual. Let's try it out by adding the model's config.
We go into the folder:
```bash
$ cd ./roberta-base-als
```
and run the following commands in a Python shell to save a config.
```python
from transformers import RobertaConfig
config = RobertaConfig.from_pretrained("FacebookAI/roberta-base")
config.save_pretrained("./")
```
Now we've added a `config.json` file and can upload it by running
```bash
$ git add . && git commit -m "add config" && git push
```
Cool! The file is now displayed on the model page under the [files tab](https://huggingface.co/flax-community/roberta-base-als/tree/main).
We encourage you to upload all files except maybe the actual data files to the repository. This includes training scripts, model weights,
model configurations, training logs, etc...
Next, let's create a tokenizer and save it to the model dir by following the instructions of the [official Flax MLM README](https://github.com/huggingface/transformers/tree/main/examples/flax/language-modeling#train-tokenizer). We can again use a simple Python shell.
```python
from datasets import load_dataset
from tokenizers import ByteLevelBPETokenizer
# load dataset
dataset = load_dataset("oscar", "unshuffled_deduplicated_als", split="train")
# Instantiate tokenizer
tokenizer = ByteLevelBPETokenizer()
def batch_iterator(batch_size=1000):
for i in range(0, len(dataset), batch_size):
yield dataset[i: i + batch_size]["text"]
# Customized training
tokenizer.train_from_iterator(batch_iterator(), vocab_size=50265, min_frequency=2, special_tokens=[
"<s>",
"<pad>",
"</s>",
"<unk>",
"<mask>",
])
# Save files to disk
tokenizer.save("./tokenizer.json")
```
This creates and saves our tokenizer directly in the cloned repository.
Finally, we can start training. For now, we'll simply use the official [`run_mlm_flax`](https://github.com/huggingface/transformers/blob/main/examples/flax/language-modeling/run_mlm_flax.py)
script, but we might make some changes later. So let's copy the script into our model repository.
```bash
$ cp ~/transformers/examples/flax/language-modeling/run_mlm_flax.py ./
```
This way we are certain to have all the code used to train the model tracked in our repository.
Let's start training by running:
```bash
./run_mlm_flax.py \
--output_dir="./" \
--model_type="roberta" \
--config_name="./" \
--tokenizer_name="./" \
--dataset_name="oscar" \
--dataset_config_name="unshuffled_deduplicated_als" \
--max_seq_length="128" \
--per_device_train_batch_size="4" \
--per_device_eval_batch_size="4" \
--learning_rate="3e-4" \
--warmup_steps="1000" \
--overwrite_output_dir \
--num_train_epochs="8" \
--push_to_hub
```
Since the dataset is tiny this command should actually run in less than 5 minutes. Note that we attach
the flag ``--push_to_hub`` so that both model weights and tensorboard traces are automatically uploaded to the hub.
You can see the tensorboard directly on the model page, under the [Training metrics tab](https://huggingface.co/flax-community/roberta-base-als/tensorboard).
As you can see, it is pretty simple to upload model weights and training logs to the model hub. Since the repository
has git version control, you & your team probably already have the necessary skills to collaborate. Thanks
to `git-lfs` being integrated into the hub, model weights and other larger file can just as easily be uploaded
and changed. Finally, at Hugging Face, we believe that the model hub is a great platform to share your project
while you are still working on it:
- Bugs in training scripts can be found and corrected by anybody participating in the event
- Loss curves can be analyzed directly on the model page
- Model weights can be accessed and analyzed by everybody from the model repository
If you are not using a transformers model, don't worry - you should still be able to make use of the hub's functionalities!
The [huggingface_hub](https://github.com/huggingface/huggingface_hub) allows you to upload essentially any JAX/Flax model to the hub with
just a couple of lines of code. *E.g.* assuming you want to call your model simply `flax-model-dummy`, you can upload it to the hub with
just three lines of code:
```python
from flax import serialization
from jax import random
from flax import linen as nn
from huggingface_hub import Repository
model = nn.Dense(features=5)
key1, key2 = random.split(random.PRNGKey(0))
x = random.normal(key1, (10,))
params = model.init(key2, x)
bytes_output = serialization.to_bytes(params)
repo = Repository("flax-model", clone_from="flax-community/flax-model-dummy", token=True)
with repo.commit("My cool Flax model :)"):
with open("flax_model.msgpack", "wb") as f:
f.write(bytes_output)
# Repo is created and available here: https://huggingface.co/flax-community/flax-model-dummy
```
**Note**: Make sure to have `huggingface_hub >= 0.0.13` to make this command work.
For more information, check out [this PR](https://github.com/huggingface/huggingface_hub/pull/143) on how to upload any framework to the hub.
## How to setup TPU VM
In this section we will explain how you can ssh into a TPU VM that has been given to your team.
If your username is in one of the officially defined projects [here](https://docs.google.com/spreadsheets/d/1GpHebL7qrwJOc9olTpIPgjf8vOS0jNb6zR_B8x_Jtik/edit?usp=sharing), you should have received two emails:
- one that states that you have been granted the role "Community Week Participants" for the project hf-flax, and
- one (or more if you are in multiple projects) that gives you the TPU name and the TPU zone for the TPU of your team
You should click on "Open Cloud Console" on the first mail and agree to the pop up windows that follows. It will allow you to use a TPU VM. Don't worry if you cannot access the actual project `hf-flax` visually on the google cloud console and receive an error:
```
You don't have sufficient permission to view this page
```
- this is expected!
Great, now you and your team can access your TPU VM!
In the following, we will describe how to do so using a standard console, but you should also be able to connect to the TPU VM via IDEs, like Visual Studio Code, etc.
1. You need to install the Google Cloud SDK. Please follow the instructions on [cloud.google.com/sdk](https://cloud.google.com/sdk/docs/install#linux).
2. Once you've installed the google cloud sdk, you should set your account by running the following command. Make sure that `<your-email-address>` corresponds to the gmail address you used to sign up for this event.
```bash
$ gcloud config set account <your-email-address>
```
3. Let's also make sure the correct project is set in case your email is used for multiple gcloud projects:
```bash
$ gcloud config set project hf-flax
```
4. Next, you will need to authenticate yourself. You can do so by running:
```bash
$ gcloud auth login
```
This should give you a link to a website, where you can authenticate your gmail account.
5. Finally, you can ssh into the TPU VM! Please run the following command by setting <zone> to either `europe-west4-a` or `us-central1-a` (depending on what is stated in the second email you received) and <tpu-name> to the TPU name also sent to you in the second email.
```bash
$ gcloud alpha compute tpus tpu-vm ssh <tpu-name> --zone <zone> --project hf-flax
```
This should ssh you into the TPU VM!
Now you can follow the steps of the section [How to install relevant libraries](#how-to-install-relevant-libraries) to install all necessary
libraries. Make sure to carefully follow the explanations of the "**IMPORTANT**" statement to correctly install JAX on TPU.
Also feel free to install other `python` or `apt` packages on your machine if it helps you to work more efficiently!
## How to build a demo
### Using the Hugging Face Widgets
Hugging Face has over [15 widgets](https://huggingface-widgets.netlify.app/) for different use cases using 🤗 Transformers library. Some of them also support [3rd party libraries](https://huggingface.co/docs/hub/libraries) such as [Sentence Similarity](https://huggingface.co/sentence-transformers/paraphrase-xlm-r-multilingual-v1) with Sentence Transformers and [Text to Speech](https://huggingface.co/julien-c/ljspeech_tts_train_tacotron2_raw_phn_tacotron_g2p_en_no_space_train) with [ESPnet](https://github.com/espnet/espnet).
All the widgets are open sourced in the `huggingface_hub` [repo](https://github.com/huggingface/huggingface_hub/tree/main/widgets). Here is a summary of existing widgets:
**NLP**
* **Conversational:** To have the best conversations!. [Example](https://huggingface.co/microsoft/DialoGPT-large?).
* **Feature Extraction:** Retrieve the input embeddings. [Example](https://huggingface.co/sentence-transformers/distilbert-base-nli-mean-tokens?text=test).
* **Fill Mask:** Predict potential words for a mask token. [Example](https://huggingface.co/google-bert/bert-base-uncased?).
* **Question Answering:** Given a context and a question, predict the answer. [Example](https://huggingface.co/google-bert/bert-large-uncased-whole-word-masking-finetuned-squad).
* **Sentence Simmilarity:** Predict how similar a set of sentences are. Useful for Sentence Transformers.

You can propose and implement new widgets by [opening an issue](https://github.com/huggingface/huggingface_hub/issues). Contributions are welcomed!
### Using a Streamlit demo
Sometimes you might be using different libraries or a very specific application that is not well supported by the current widgets. In this case, [Streamlit](https://streamlit.io/) can be an excellent option to build a cool visual demo. Setting up a Streamlit application is straightforward and in Python!
A common use case is how to load files you have in your model repository in the Hub from the Streamlit demo. The `huggingface_hub` library is here to help you!
```bash
pip install huggingface_hub
```
Here is an example downloading (and caching!) a specific file directly from the Hub
```python
from huggingface_hub import hf_hub_download
filepath = hf_hub_download("flax-community/roberta-base-als", "flax_model.msgpack");
```
In many cases you will want to download the full repository. Here is an example downloading all the files from a repo. You can even specify specific revisions!
```python
from huggingface_hub import snapshot_download
local_path = snapshot_download("flax-community/roberta-base-als");
```
Note that if you're using 🤗 Transformers library, you can quickly load the model and tokenizer as follows
```python
from transformers import AutoTokenizer, AutoModelForMaskedLM
tokenizer = AutoTokenizer.from_pretrained("REPO_ID")
model = AutoModelForMaskedLM.from_pretrained("REPO_ID")
```
We'll provide more examples on Streamlit demos next week. Stay tuned!
### Using a Gradio demo
You can also use [Gradio](https://gradio.app/) to share your demos! [Here](https://huggingface.co/blog/gradio) is an example using the Gradio library to create a GUI for a Hugging Face model.
More to come!

# Model parallel language model training example
The following example showcases how to train/fine-tune GPTNeo model with model parallelism using
the JAX/Flax backend and the [`pjit`](https://jax.readthedocs.io/en/latest/jax.experimental.pjit.html) transformation.
> Note: The example is experimental and might have bugs. Also currently it only supports single V3-8.
The `partition.py` file defines the `PyTree` of `ParitionSpec` for the GPTNeo model which describes how the model will be sharded.
The actual sharding is auto-matically handled by `pjit`. The weights are sharded across all local devices.
To adapt the script for other models, we need to also change the `ParitionSpec` accordingly.
TODO: Add more explantion.
Before training, let's prepare our model first. To be able to shard the model, the sharded dimension needs to be a multiple of devices it'll be sharded on. But GPTNeo's vocab size is 50257, so we need to resize the embeddings accordingly.
```python
from transformers import FlaxGPTNeoForCausalLM, GPTNeoConfig
model = FlaxGPTNeoForCausalLM.from_pretrained("EleutherAI/gpt-neo-1.3B")
emb = jnp.zeros((50264, model.config.hidden_size))
# update the first 50257 weights using pre-trained weights
emb = emb.at[:50257, :].set(model.params["transformer"]["wte"]["embedding"])
params = model.params
params["transformer"]["wte"]["embedding"] = emb
# initialize a random model with the right vocab_size
config = GPTNeoConfig.from_pretrained("EleutherAI/gpt-neo-1.3B", vocab_size=50264)
model = FlaxGPTNeoForCausalLM(config)
# assign the pre-trained weights and save the model.
model.params = params
model.save_pretrained("gpt-neo-1.3B")
```
### Train Model
```bash
python run_clm_mp.py \
--model_name_or_path gpt-neo-1.3B \
--tokenizer_name openai-community/gpt2 \
--dataset_name wikitext --dataset_config_name wikitext-2-raw-v1 \
--do_train --do_eval \
--block_size 1024 \
--num_train_epochs 5 \
--learning_rate 4e-6 \
--per_device_train_batch_size 3 --per_device_eval_batch_size 3 \
--overwrite_output_dir --output_dir ~/tmp/flax-clm \
--cache_dir ~/datasets_cache/wikitext --dtype bfloat16 \
--logging_steps 96 --eval_steps 96

# Language model training examples in streaming mode
The following examples showcase how to train a language model from scratch
using the JAX/Flax backend.
JAX/Flax allows you to trace pure functions and compile them into efficient, fused accelerator code on both GPU and TPU.
Models written in JAX/Flax are **immutable** and updated in a purely functional
way which enables simple and efficient model parallelism.
All of the following examples make use of [dataset streaming](https://huggingface.co/docs/datasets/master/dataset_streaming), therefore allowing to train models on massive datasets\
without ever having to download the full dataset.
## Masked language modeling
In the following, we demonstrate how to train a bi-directional transformer model
using masked language modeling objective as introduced in [BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding](https://arxiv.org/abs/1810.04805).
More specifically, we demonstrate how JAX/Flax and dataset streaming can be leveraged
to pre-train [**`FacebookAI/roberta-base`**](https://huggingface.co/FacebookAI/roberta-base)
in English on a single TPUv3-8 pod for 10000 update steps.
The example script uses the 🤗 Datasets library. You can easily customize them to your needs if you need extra processing on your datasets.
Let's start by creating a model repository to save the trained model and logs.
Here we call the model `"english-roberta-base-dummy"`, but you can change the model name as you like.
You can do this either directly on [huggingface.co](https://huggingface.co/new) (assuming that
you are logged in) or via the command line:
```bash
huggingface-cli repo create english-roberta-base-dummy
```
Next we clone the model repository to add the tokenizer and model files.
```bash
git clone https://huggingface.co/<your-username>/english-roberta-base-dummy
```
To ensure that all tensorboard traces will be uploaded correctly, we need to
track them. You can run the following command inside your model repo to do so.
```bash
cd english-roberta-base-dummy
git lfs track "*tfevents*"
```
Great, we have set up our model repository. During training, we will automatically
push the training logs and model weights to the repo.
Next, let's add a symbolic link to the `run_mlm_flax.py`.
```bash
export MODEL_DIR="./english-roberta-base-dummy"
ln -s ~/transformers/examples/research_projects/jax-projects/dataset-streaming/run_mlm_flax_stream.py ./
```
### Copy config and tokenizer of existing model
In this example, we will simply copy an existing config and tokenizer in English.
You can run the following code in a Python shell to do so.
```python
from transformers import RobertaTokenizerFast, RobertaConfig
model_dir = "./english-roberta-base-dummy"
tokenizer = RobertaTokenizerFast.from_pretrained("FacebookAI/roberta-base")
config = RobertaConfig.from_pretrained("FacebookAI/roberta-base")
tokenizer.save_pretrained(model_dir)
config.save_pretrained(model_dir)
```
### Train model
Next we can run the example script to pretrain the model.
Compared to the default [`run_mlm_flax`](https://github.com/huggingface/transformers/blob/main/examples/flax/language-modeling/run_mlm_flax.py), we introduced 4 new training settings:
- `num_train_steps` - how many update steps should be run.
- `num_eval_samples` - how many training samples should be taken for evaluation.
- `logging_steps` - at what rate should the training loss be logged.
- `eval_steps` - at what rate should evaluation be run.
10K update steps
```bash
./run_mlm_flax_stream.py \
--output_dir="${MODEL_DIR}" \
--model_type="roberta" \
--config_name="${MODEL_DIR}" \
--tokenizer_name="${MODEL_DIR}" \
--dataset_name="oscar" \
--dataset_config_name="unshuffled_deduplicated_en" \
--max_seq_length="128" \
--per_device_train_batch_size="128" \
--per_device_eval_batch_size="128" \
--learning_rate="3e-4" \
--warmup_steps="1000" \
--overwrite_output_dir \
--adam_beta1="0.9" \
--adam_beta2="0.98" \
--num_train_steps="10000" \
--num_eval_samples="5000" \
--logging_steps="250" \
--eval_steps="1000" \
--push_to_hub
```

Author: [@vasudevgupta7](https://github.com/thevasudevgupta/)
## Intro
In this project, we fine-tuned [**BigBird**](https://arxiv.org/abs/2007.14062) on [**natural-questions**](https://huggingface.co/datasets/natural_questions) dataset for **question-answering** task on long documents. **BigBird**, is a **sparse-attention based transformer** which extends Transformer based models, such as BERT to much **longer sequences**.
Read more about BigBird at https://huggingface.co/blog/big-bird
## Fine-tuning
**Setup**
You need to install jax yourself by following the official docs ([refer this](https://github.com/google/jax#installation)). Other requirements for this project can be installed by running following command:
```shell
pip3 install -qr requirements.txt
```
**Download & prepare dataset**
The Natural Questions corpus contains questions from real users, and it requires QA systems to read and comprehend an entire Wikipedia article that may or may not contain the answer to the question. This corpus takes ~100 GB on disk. We have used HuggingFace datasets to download & process the dataset.
```shell
# just run following CMD
python3 prepare_natural_questions.py
# this will download the whole dataset from HuggingFace Hub & will make it ready for training
# this script takes ~3 hours to process the dataset
```
**Launch Training**
We have trained on Cloud's TPU v3-8. Each epoch took around 4.5 hours and the model got converged in just 2 epochs. You can see complete training args in [this script](bigbird_flax.py).
```shell
# just run following CMD
python3 train.py
# In case, you want to try hparams tuning, you can run wandb sweep
wandb sweep --project=bigbird sweep_flax.yaml
wandb agent <agent-id-obtained-by-above-CMD>
```
## Evaluation
Our evaluation script is different from the original script and we are evaluating sequences with length up to 4096 for simplicity. We managed to get the **EM score of ~55.2** using our evaluation script.
```shell
# download validation-dataset first
mkdir natural-questions-validation
wget https://huggingface.co/datasets/vasudevgupta/natural-questions-validation/resolve/main/natural_questions-validation.arrow -P natural-questions-validation
wget https://huggingface.co/datasets/vasudevgupta/natural-questions-validation/resolve/main/dataset_info.json -P natural-questions-validation
wget https://huggingface.co/datasets/vasudevgupta/natural-questions-validation/resolve/main/state.json -P natural-questions-validation
# simply run following command
python3 evaluate.py
```
You can find our checkpoint on HuggingFace Hub ([see this](https://huggingface.co/vasudevgupta/flax-bigbird-natural-questions)). In case you are interested in PyTorch BigBird fine-tuning, you can refer to [this repository](https://github.com/thevasudevgupta/bigbird).

- A string, the `model id` of a pretrained model hosted inside a model repo on huggingface.co.
- A path to a `directory` containing model weights saved using
:func:`~transformers.FlaxPreTrainedModel.save_pretrained`, e.g., ``./my_model_directory/``.
- A path or url to a `PyTorch checkpoint folder` (e.g, ``./pt_model``). In
this case, ``from_pt`` should be set to :obj:`True` and a configuration object should be provided
as ``config`` argument. This loading path is slower than converting the PyTorch checkpoint in
a Flax model using the provided conversion scripts and loading the Flax model afterwards.
vision_model_name_or_path (:obj: `str`, `optional`, defaults to `None`):
Information necessary to initiate the vision model. Can be either:
- A string, the `model id` of a pretrained model hosted inside a model repo on huggingface.co.
- A path to a `directory` containing model weights saved using
:func:`~transformers.FlaxPreTrainedModel.save_pretrained`, e.g., ``./my_model_directory/``.
- A path or url to a `PyTorch checkpoint folder` (e.g, ``./pt_model``). In
this case, ``from_pt`` should be set to :obj:`True` and a configuration object should be provided
as ``config`` argument. This loading path is slower than converting the PyTorch checkpoint in
a Flax model using the provided conversion scripts and loading the Flax model afterwards.
model_args (remaining positional arguments, `optional`):
All remaning positional arguments will be passed to the underlying model's ``__init__`` method.
kwargs (remaining dictionary of keyword arguments, `optional`):
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
:obj:`output_attentions=True`).
- To update the text configuration, use the prefix `text_` for each configuration parameter.
- To update the vision configuration, use the prefix `vision_` for each configuration parameter.
- To update the parent model configuration, do not use a prefix for each configuration parameter.
Behaves differently depending on whether a :obj:`config` is provided or automatically loaded.

>>> from transformers import FlaxHybridCLIP
>>> # initialize a model from pretrained BERT and CLIP models. Note that the projection layers will be randomly initialized.
>>> # If using CLIP's vision model the vision projection layer will be initialized using pre-trained weights

# Vision-Text dual encoder model training examples
> Note: This example is experimental and might not give the best possible results
The following example showcases how to train a CLIP like vision-text dual encoder model
using a pre-trained vision and text encoder using the JAX/Flax backend.
Such a model can be used for natural language image search and potentially zero-shot image classification.
The model is inspired by the [CLIP](https://openai.com/blog/clip/) approach, introduced by Alec Radford et al.
The idea is to train a vision encoder and a text encoder jointly to project the representation of images and their
captions into the same embedding space, such that the caption embeddings are located near the embeddings
of the images they describe.
JAX/Flax allows you to trace pure functions and compile them into efficient, fused accelerator code on both GPU and TPU.
Models written in JAX/Flax are **immutable** and updated in a purely functional
way which enables simple and efficient model parallelism.
In this example we will use the vision model from [CLIP](https://huggingface.co/models?filter=clip)
as the image encoder and [`FacebookAI/roberta-base`](https://huggingface.co/FacebookAI/roberta-base) as the text encoder.
Note that one can also use the [ViT](https://huggingface.co/models?filter=vit) model as image encoder and any other BERT or ROBERTa model as text encoder.
To train the model on languages other than English one should choose a text encoder trained on the desired
language and a image-text dataset in that language. One such dataset is [WIT](https://github.com/google-research-datasets/wit).
Let's start by creating a model repository to save the trained model and logs.
Here we call the model `"clip-roberta-base"`, but you can change the model name as you like.
You can do this either directly on [huggingface.co](https://huggingface.co/new) (assuming that
you are logged in) or via the command line:
```bash
huggingface-cli repo create clip-roberta-base
```
Next we clone the model repository to add the tokenizer and model files.
```bash
git clone https://huggingface.co/<your-username>/clip-roberta-base
```
To ensure that all tensorboard traces will be uploaded correctly, we need to
track them. You can run the following command inside your model repo to do so.
```bash
cd clip-roberta-base
git lfs track "*tfevents*"
```
Great, we have set up our model repository. During training, we will automatically
push the training logs and model weights to the repo.
Next, let's add a symbolic link to the `run_hybrid_clip.py`.
```bash
export MODEL_DIR="./clip-roberta-base
ln -s ~/transformers/examples/research_projects/jax-projects/hybrid_clip/run_hybrid_clip.py run_hybrid_clip.py
```
## How to use the `FlaxHybridCLIP` model:
The `FlaxHybridCLIP` class let's you load any text and vision encoder model to create a dual encoder.
Here is an example of how to load the model using pre-trained text and vision models.
```python
from modeling_hybrid_clip import FlaxHybridCLIP
model = FlaxHybridCLIP.from_text_vision_pretrained("google-bert/bert-base-uncased", "openai/clip-vit-base-patch32")
# save the model
model.save_pretrained("bert-clip")
# load the saved model
model = FlaxHybridCLIP.from_pretrained("bert-clip")
```
If the checkpoints are in PyTorch then one could pass `text_from_pt=True` and `vision_from_pt=True`. This will load the model
PyTorch checkpoints convert them to flax and load the model.
```python
model = FlaxHybridCLIP.from_text_vision_pretrained("google-bert/bert-base-uncased", "openai/clip-vit-base-patch32", text_from_pt=True, vision_from_pt=True)
```
This loads both the text and vision encoders using pre-trained weights, the projection layers are randomly
initialized except for CLIP's vision model. If you use CLIP to initialize the vision model then the vision projection weights are also
loaded using the pre-trained weights.
## Prepare the dataset
We will use the MS-COCO dataset to train our dual encoder model. MS-COCO contains over 82,000 images, each of which has at least 5 different caption annotations. The dataset is usually used for image captioning tasks, but we can repurpose the image-caption pairs to train our dual encoder model for image search.
### Download and extract the data.
It consists of two compressed folders: one with images, and the other—with associated image captions. Note that the compressed images folder is 13GB in size.
```bash
wget http://images.cocodataset.org/annotations/annotations_trainval2014.zip
wget http://images.cocodataset.org/zips/train2014.zip
unzip annotations_trainval2014.zip
unzip train2014.zip
mkdir coco_dataset
mv train2014 coco_dataset/
mv annotations coco_dataset/
```
### Prepare dataset files and split the dataset.
```python
import json
import collections
images_dir = "coco_dataset/train2014"
annotation_file = "coco_dataset/annotations/captions_train2014.json"
with open(annotation_file, "r") as f:
annotations = json.load(f)["annotations"]
image_path_to_caption = collections.defaultdict(list)
for element in annotations:
caption = f"{element['caption'].lower().rstrip('.')}"
image_path = images_dir + "/COCO_train2014_" + "%012d.jpg" % (element["image_id"])
image_path_to_caption[image_path].append(caption)
lines = []
for image_path, captions in image_path_to_caption.items():
lines.append(json.dumps({"image_path": image_path, "captions": captions}))
train_lines = lines[:-8000]
valid_line = lines[-8000:]
with open("coco_dataset/train_dataset.json", "w") as f:
f.write("\n".join(train_lines))
with open("coco_dataset/valid_dataset.json", "w") as f:
f.write("\n".join(valid_line))
```
> Note: The data loading and processing part of this script can still be improved for maximum performance. In particular one should decode the images beforehand and use those instead decoding them each time. If the dataset is small or if you have huge disk space the you could also pre-process all the dataset beforehand and then use it.
## Train the model
Next we can run the example script to train the model:
```bash
python run_hybrid_clip.py \
--output_dir ${MODEL_DIR} \
--text_model_name_or_path="FacebookAI/roberta-base" \
--vision_model_name_or_path="openai/clip-vit-base-patch32" \
--tokenizer_name="FacebookAI/roberta-base" \
--train_file="coco_dataset/train_dataset.json" \
--validation_file="coco_dataset/validation_dataset.json" \
--do_train --do_eval \
--num_train_epochs="40" --max_seq_length 96 \
--per_device_train_batch_size="64" \
--per_device_eval_batch_size="64" \
--learning_rate="5e-5" --warmup_steps="0" --weight_decay 0.1 \
--overwrite_output_dir \
--preprocessing_num_workers 32 \
--push_to_hub
```
This should finish in ~1h50 mins with min validation loss 2.43. Training statistics can be accessed on [tfhub.de](https://tensorboard.dev/experiment/RUNPYd1yRgSD5kZSb9hDig/#scalars)

mavonic_private_repos/transformers/examples/research_projects/jax-projects | mavonic_private_repos/transformers/examples/research_projects/jax-projects/wav2vec2/README.md | # Wav2Vec2 Contrastive Loss PreTraining examples
The following example showcases how to pretrain a wav2vec2 model using the JAX/Flax backend.
Pretraining Wav2Vec2 is rather complex, so it is highly recommended to read the
[official paper](https://arxiv.org/abs/2006.11477).
JAX/Flax allows you to trace pure functions and compile them into efficient, fused accelerator code on both GPU and TPU.
Models written in JAX/Flax are **immutable** and updated in a purely functional
way which enables simple and efficient model parallelism.
`run_wav2vec2_pretrain_flax.py` is a lightweight example of how to download and preprocess a dataset from the 🤗 Datasets library or use your own files (jsonlines or csv), then pretrain the wav2vec2 architectures above on it.
For custom datasets in `jsonlines` format please see: [the Datasets documentation](https://huggingface.co/docs/datasets/loading_datasets#json-files) and you also will find examples of these below.
Let's start by creating a model repository to save the trained model and logs.
Here we call the model `"wav2vec2-base-robust"`, but you can change the model name as you like.
You can do this either directly on [huggingface.co](https://huggingface.co/new) (assuming that
you are logged in) or via the command line:
```bash
huggingface-cli repo create wav2vec2-base-robust
```
Next we clone the model repository to add the tokenizer and model files.
```bash
git clone https://huggingface.co/<your-username>/wav2vec2-base-robust
```
To ensure that all tensorboard traces will be uploaded correctly, we need to
track them. You can run the following command inside your model repo to do so.
```bash
cd wav2vec2-base-robust
git lfs track "*tfevents*"
```
Great, we have set up our model repository. During training, we will automatically
push the training logs and model weights to the repo.
Next, let's add a symbolic link to the `run_wav2vec2_pretrain_flax`.
```bash
export MODEL_DIR="./wav2vec2-base-robust"
ln -s ~/transformers/examples/research_projects/jax-projects/wav2vec2/run_wav2vec2_pretrain_flax.py ./
```
### Create the model configuration
Let's first create the model configuration and store it in the model repository.
Note that many training parameters can be set in the model configuration including
the configuration about the masking distribution (`mask_time_length`, `mask_time_prob`),
dropout (`attention_dropout`, ...), the trade-off between the contrastive loss and
the diversity loss, etc...
Mostly likely you will need to change these parameters depending on your use case.
Again, we highly recommend to read the [official paper](https://arxiv.org/abs/2006.11477)
to better understand which parameters can be set for pretraining.
For this example, we will be using a `"base"`-sized model of Wav2Vec2 with robust
layer norm and keep most of the default settings.
```python
model_dir="./wav2vec2-base-robust"
from transformers import Wav2Vec2Config
config = Wav2Vec2Config.from_pretrained(
"facebook/wav2vec2-base",
mask_time_length=10,
mask_time_prob=0.05,
diversity_loss_weight=0.1,
num_negatives=100,
do_stable_layer_norm=True,
feat_extract_norm="layer",
)
config.save_pretrained(model_dir)
```
### Create a feature extractor configuration
Before we can start the training, we need to define
a feature extractor that takes care of normalization, etc...
Here we can also re-use the feature extractor of [wav2vec2-base-960h](https://huggingface.co/facebook/wav2vec2-base) while making sure that padding is allowed.
```python
model_dir="./wav2vec2-base-robust"
from transformers import Wav2Vec2FeatureExtractor
config = Wav2Vec2FeatureExtractor.from_pretrained("facebook/wav2vec2-base", return_attention_mask=True)
config.save_pretrained(model_dir)
```
### Train the model
Finally, we can run the example script to train the model:
```bash
./run_wav2vec2_pretrain_flax.py \
--output_dir=${MODEL_DIR} \
--num_train_epochs="5" \
--per_device_train_batch_size="32" \
--per_device_eval_batch_size="32" \
--learning_rate="5e-4" \
--weight_decay="0.01" \
--warmup_steps="2000" \
--model_name_or_path=${MODEL_DIR} \
--dataset_name="librispeech_asr" \
--dataset_config_name="clean" \
--train_split_name="train.100" \
--preprocessing_num_workers="4" \
--max_duration_in_seconds="10.0" \
--adam_beta1="0.9" \
--adam_beta2="0.98" \
--pad_to_multiple_of="16384" \
--push_to_hub
```
Note that this script is not fully tested yet, so we cannot ensure that
the above script leads to satisfying results.

mavonic_private_repos/transformers/examples/legacy | mavonic_private_repos/transformers/examples/legacy/token-classification/README.md | ## Token classification
Based on the scripts [`run_ner.py`](https://github.com/huggingface/transformers/blob/main/examples/legacy/token-classification/run_ner.py).
The following examples are covered in this section:
* NER on the GermEval 2014 (German NER) dataset
* Emerging and Rare Entities task: WNUT’17 (English NER) dataset
Details and results for the fine-tuning provided by @stefan-it.
### GermEval 2014 (German NER) dataset
#### Data (Download and pre-processing steps)
Data can be obtained from the [GermEval 2014](https://sites.google.com/site/germeval2014ner/data) shared task page.
Here are the commands for downloading and pre-processing train, dev and test datasets. The original data format has four (tab-separated) columns, in a pre-processing step only the two relevant columns (token and outer span NER annotation) are extracted:
```bash
curl -L 'https://drive.google.com/uc?export=download&id=1Jjhbal535VVz2ap4v4r_rN1UEHTdLK5P' \
| grep -v "^#" | cut -f 2,3 | tr '\t' ' ' > train.txt.tmp
curl -L 'https://drive.google.com/uc?export=download&id=1ZfRcQThdtAR5PPRjIDtrVP7BtXSCUBbm' \
| grep -v "^#" | cut -f 2,3 | tr '\t' ' ' > dev.txt.tmp
curl -L 'https://drive.google.com/uc?export=download&id=1u9mb7kNJHWQCWyweMDRMuTFoOHOfeBTH' \
| grep -v "^#" | cut -f 2,3 | tr '\t' ' ' > test.txt.tmp
```
The GermEval 2014 dataset contains some strange "control character" tokens like `'\x96', '\u200e', '\x95', '\xad' or '\x80'`.
One problem with these tokens is, that `BertTokenizer` returns an empty token for them, resulting in misaligned `InputExample`s.
The `preprocess.py` script located in the `scripts` folder a) filters these tokens and b) splits longer sentences into smaller ones (once the max. subtoken length is reached).
Let's define some variables that we need for further pre-processing steps and training the model:
```bash
export MAX_LENGTH=128
export BERT_MODEL=google-bert/bert-base-multilingual-cased
```
Run the pre-processing script on training, dev and test datasets:
```bash
python3 scripts/preprocess.py train.txt.tmp $BERT_MODEL $MAX_LENGTH > train.txt
python3 scripts/preprocess.py dev.txt.tmp $BERT_MODEL $MAX_LENGTH > dev.txt
python3 scripts/preprocess.py test.txt.tmp $BERT_MODEL $MAX_LENGTH > test.txt
```
The GermEval 2014 dataset has much more labels than CoNLL-2002/2003 datasets, so an own set of labels must be used:
```bash
cat train.txt dev.txt test.txt | cut -d " " -f 2 | grep -v "^$"| sort | uniq > labels.txt
```
#### Prepare the run
Additional environment variables must be set:
```bash
export OUTPUT_DIR=germeval-model
export BATCH_SIZE=32
export NUM_EPOCHS=3
export SAVE_STEPS=750
export SEED=1
```
#### Run the Pytorch version
To start training, just run:
```bash
python3 run_ner.py --data_dir ./ \
--labels ./labels.txt \
--model_name_or_path $BERT_MODEL \
--output_dir $OUTPUT_DIR \
--max_seq_length $MAX_LENGTH \
--num_train_epochs $NUM_EPOCHS \
--per_device_train_batch_size $BATCH_SIZE \
--save_steps $SAVE_STEPS \
--seed $SEED \
--do_train \
--do_eval \
--do_predict
```
If your GPU supports half-precision training, just add the `--fp16` flag. After training, the model will be both evaluated on development and test datasets.
#### JSON-based configuration file
Instead of passing all parameters via commandline arguments, the `run_ner.py` script also supports reading parameters from a json-based configuration file:
```json
{
"data_dir": ".",
"labels": "./labels.txt",
"model_name_or_path": "google-bert/bert-base-multilingual-cased",
"output_dir": "germeval-model",
"max_seq_length": 128,
"num_train_epochs": 3,
"per_device_train_batch_size": 32,
"save_steps": 750,
"seed": 1,
"do_train": true,
"do_eval": true,
"do_predict": true
}
```
It must be saved with a `.json` extension and can be used by running `python3 run_ner.py config.json`.
#### Evaluation
Evaluation on development dataset outputs the following for our example:
```bash
10/04/2019 00:42:06 - INFO - __main__ - ***** Eval results *****
10/04/2019 00:42:06 - INFO - __main__ - f1 = 0.8623348017621146
10/04/2019 00:42:06 - INFO - __main__ - loss = 0.07183869666975543
10/04/2019 00:42:06 - INFO - __main__ - precision = 0.8467916366258111
10/04/2019 00:42:06 - INFO - __main__ - recall = 0.8784592370979806
```
On the test dataset the following results could be achieved:
```bash
10/04/2019 00:42:42 - INFO - __main__ - ***** Eval results *****
10/04/2019 00:42:42 - INFO - __main__ - f1 = 0.8614389652384803
10/04/2019 00:42:42 - INFO - __main__ - loss = 0.07064602487454782
10/04/2019 00:42:42 - INFO - __main__ - precision = 0.8604651162790697
10/04/2019 00:42:42 - INFO - __main__ - recall = 0.8624150210424085
```
#### Run the Tensorflow 2 version
To start training, just run:
```bash
python3 run_tf_ner.py --data_dir ./ \
--labels ./labels.txt \
--model_name_or_path $BERT_MODEL \
--output_dir $OUTPUT_DIR \
--max_seq_length $MAX_LENGTH \
--num_train_epochs $NUM_EPOCHS \
--per_device_train_batch_size $BATCH_SIZE \
--save_steps $SAVE_STEPS \
--seed $SEED \
--do_train \
--do_eval \
--do_predict
```
Such as the Pytorch version, if your GPU supports half-precision training, just add the `--fp16` flag. After training, the model will be both evaluated on development and test datasets.
#### Evaluation
Evaluation on development dataset outputs the following for our example:
```bash

### Emerging and Rare Entities task: WNUT’17 (English NER) dataset
Description of the WNUT’17 task from the [shared task website](http://noisy-text.github.io/2017/index.html):
> The WNUT’17 shared task focuses on identifying unusual, previously-unseen entities in the context of emerging discussions.
> Named entities form the basis of many modern approaches to other tasks (like event clustering and summarization), but recall on
> them is a real problem in noisy text - even among annotators. This drop tends to be due to novel entities and surface forms.
Six labels are available in the dataset. An overview can be found on this [page](http://noisy-text.github.io/2017/files/).
#### Data (Download and pre-processing steps)
The dataset can be downloaded from the [official GitHub](https://github.com/leondz/emerging_entities_17) repository.
The following commands show how to prepare the dataset for fine-tuning:
```bash
mkdir -p data_wnut_17
curl -L 'https://github.com/leondz/emerging_entities_17/raw/master/wnut17train.conll' | tr '\t' ' ' > data_wnut_17/train.txt.tmp
curl -L 'https://github.com/leondz/emerging_entities_17/raw/master/emerging.dev.conll' | tr '\t' ' ' > data_wnut_17/dev.txt.tmp
curl -L 'https://raw.githubusercontent.com/leondz/emerging_entities_17/master/emerging.test.annotated' | tr '\t' ' ' > data_wnut_17/test.txt.tmp
```
Let's define some variables that we need for further pre-processing steps:
```bash
export MAX_LENGTH=128
export BERT_MODEL=google-bert/bert-large-cased
```
Here we use the English BERT large model for fine-tuning.
The `preprocess.py` scripts splits longer sentences into smaller ones (once the max. subtoken length is reached):
```bash
python3 scripts/preprocess.py data_wnut_17/train.txt.tmp $BERT_MODEL $MAX_LENGTH > data_wnut_17/train.txt
python3 scripts/preprocess.py data_wnut_17/dev.txt.tmp $BERT_MODEL $MAX_LENGTH > data_wnut_17/dev.txt
python3 scripts/preprocess.py data_wnut_17/test.txt.tmp $BERT_MODEL $MAX_LENGTH > data_wnut_17/test.txt
```
In the last pre-processing step, the `labels.txt` file needs to be generated. This file contains all available labels:
```bash
cat data_wnut_17/train.txt data_wnut_17/dev.txt data_wnut_17/test.txt | cut -d " " -f 2 | grep -v "^$"| sort | uniq > data_wnut_17/labels.txt
```
#### Run the Pytorch version
Fine-tuning with the PyTorch version can be started using the `run_ner.py` script. In this example we use a JSON-based configuration file.
This configuration file looks like:
```json
{
"data_dir": "./data_wnut_17",
"labels": "./data_wnut_17/labels.txt",
"model_name_or_path": "google-bert/bert-large-cased",
"output_dir": "wnut-17-model-1",
"max_seq_length": 128,
"num_train_epochs": 3,
"per_device_train_batch_size": 32,
"save_steps": 425,
"seed": 1,
"do_train": true,
"do_eval": true,
"do_predict": true,
"fp16": false
}
```
If your GPU supports half-precision training, please set `fp16` to `true`.
Save this JSON-based configuration under `wnut_17.json`. The fine-tuning can be started with `python3 run_ner_old.py wnut_17.json`.
#### Evaluation
Evaluation on development dataset outputs the following:
```bash
05/29/2020 23:33:44 - INFO - __main__ - ***** Eval results *****
05/29/2020 23:33:44 - INFO - __main__ - eval_loss = 0.26505235286212275

05/29/2020 23:33:44 - INFO - __main__ - epoch = 3.0
```
On the test dataset the following results could be achieved:
```bash
05/29/2020 23:33:44 - INFO - transformers.trainer - ***** Running Prediction *****
05/29/2020 23:34:02 - INFO - __main__ - eval_loss = 0.30948806500973547

mavonic_private_repos/transformers/examples/legacy | mavonic_private_repos/transformers/examples/legacy/seq2seq/romanian_postprocessing.md | ### Motivation
Without processing, english-> romanian mbart-large-en-ro gets BLEU score 26.8 on the WMT data.
With post processing, it can score 37..
Here is the postprocessing code, stolen from @mjpost in this [issue](https://github.com/pytorch/fairseq/issues/1758)
### Instructions
Note: You need to have your test_generations.txt before you start this process.
(1) Setup `mosesdecoder` and `wmt16-scripts`
```bash
cd $HOME
git clone git@github.com:moses-smt/mosesdecoder.git
cd mosesdecoder
git clone git@github.com:rsennrich/wmt16-scripts.git
```
(2) define a function for post processing.
It removes diacritics and does other things I don't understand
```bash
ro_post_process () {
sys=$1
ref=$2
export MOSES_PATH=$HOME/mosesdecoder
REPLACE_UNICODE_PUNCT=$MOSES_PATH/scripts/tokenizer/replace-unicode-punctuation.perl
NORM_PUNC=$MOSES_PATH/scripts/tokenizer/normalize-punctuation.perl
REM_NON_PRINT_CHAR=$MOSES_PATH/scripts/tokenizer/remove-non-printing-char.perl
REMOVE_DIACRITICS=$MOSES_PATH/wmt16-scripts/preprocess/remove-diacritics.py
NORMALIZE_ROMANIAN=$MOSES_PATH/wmt16-scripts/preprocess/normalise-romanian.py
TOKENIZER=$MOSES_PATH/scripts/tokenizer/tokenizer.perl
lang=ro
for file in $sys $ref; do
cat $file \
| $REPLACE_UNICODE_PUNCT \
| $NORM_PUNC -l $lang \
| $REM_NON_PRINT_CHAR \
| $NORMALIZE_ROMANIAN \
| $REMOVE_DIACRITICS \
| $TOKENIZER -no-escape -l $lang \
> $(basename $file).tok
done
# compute BLEU
cat $(basename $sys).tok | sacrebleu -tok none -s none -b $(basename $ref).tok
}
```
(3) Call the function on test_generations.txt and test.target
For example,
```bash
ro_post_process enro_finetune/test_generations.txt wmt_en_ro/test.target
```
This will split out a new blue score and write a new fine called `test_generations.tok` with post-processed outputs.
```

wget https://cdn-datasets.huggingface.co/summarization/xsum.tar.gz
tar -xzvf xsum.tar.gz
export XSUM_DIR=${PWD}/xsum
```
this should make a directory called `xsum/` with files like `test.source`.
To use your own data, copy that files format. Each article to be summarized is on its own line.
#### CNN/DailyMail
```bash
cd examples/legacy/seq2seq
wget https://cdn-datasets.huggingface.co/summarization/cnn_dm_v2.tgz
tar -xzvf cnn_dm_v2.tgz # empty lines removed
mv cnn_cln cnn_dm
export CNN_DIR=${PWD}/cnn_dm
```
this should make a directory called `cnn_dm/` with 6 files.
#### WMT16 English-Romanian Translation Data
download with this command:
```bash
wget https://cdn-datasets.huggingface.co/translation/wmt_en_ro.tar.gz
tar -xzvf wmt_en_ro.tar.gz
export ENRO_DIR=${PWD}/wmt_en_ro
```
this should make a directory called `wmt_en_ro/` with 6 files.
#### WMT English-German
```bash
wget https://cdn-datasets.huggingface.co/translation/wmt_en_de.tgz
tar -xzvf wmt_en_de.tgz
export DATA_DIR=${PWD}/wmt_en_de
```
#### FSMT datasets (wmt)
Refer to the scripts starting with `eval_` under:
https://github.com/huggingface/transformers/tree/main/scripts/fsmt
#### Pegasus (multiple datasets)
Multiple eval datasets are available for download from:
https://github.com/stas00/porting/tree/master/datasets/pegasus
#### Your Data
If you are using your own data, it must be formatted as one directory with 6 files:
```
train.source
train.target
val.source
val.target
test.source
test.target
```
The `.source` files are the input, the `.target` files are the desired output.
### Potential issues
- native AMP (`--fp16` and no apex) may lead to a huge memory leak and require 10x gpu memory. This has been fixed in pytorch-nightly and the minimal official version to have this fix will be pytorch-1.7.1. Until then if you have to use mixed precision please use AMP only with pytorch-nightly or NVIDIA's apex. Reference: https://github.com/huggingface/transformers/issues/8403
### Tips and Tricks
General Tips:
- since you need to run from `examples/legacy/seq2seq`, and likely need to modify code, the easiest workflow is fork transformers, clone your fork, and run `pip install -e .` before you get started.
- try `--freeze_encoder` or `--freeze_embeds` for faster training/larger batch size. (3hr per epoch with bs=8, see the "xsum_shared_task" command below)
- `fp16_opt_level=O1` (the default works best).
- In addition to the pytorch-lightning .ckpt checkpoint, a transformers checkpoint will be saved.
Load it with `BartForConditionalGeneration.from_pretrained(f'{output_dir}/best_tfmr)`.
- At the moment, `--do_predict` does not work in a multi-gpu setting. You need to use `evaluate_checkpoint` or the `run_eval.py` code.
- This warning can be safely ignored:
> "Some weights of BartForConditionalGeneration were not initialized from the model checkpoint at facebook/bart-large-xsum and are newly initialized: ['final_logits_bias']"
- Both finetuning and eval are 30% faster with `--fp16`. For that you need to [install apex](https://github.com/NVIDIA/apex#quick-start).
- Read scripts before you run them!
Summarization Tips:
- (summ) 1 epoch at batch size 1 for bart-large takes 24 hours and requires 13GB GPU RAM with fp16 on an NVIDIA-V100.
- If you want to run experiments on improving the summarization finetuning process, try the XSUM Shared Task (below). It's faster to train than CNNDM because the summaries are shorter.
- For CNN/DailyMail, the default `val_max_target_length` and `test_max_target_length` will truncate the ground truth labels, resulting in slightly higher rouge scores. To get accurate rouge scores, you should rerun calculate_rouge on the `{output_dir}/test_generations.txt` file saved by `trainer.test()`
- `--max_target_length=60 --val_max_target_length=60 --test_max_target_length=100 ` is a reasonable setting for XSUM.
- `wandb` can be used by specifying `--logger_name wandb`. It is useful for reproducibility. Specify the environment variable `WANDB_PROJECT='hf_xsum'` to do the XSUM shared task.
- If you are finetuning on your own dataset, start from `distilbart-cnn-12-6` if you want long summaries and `distilbart-xsum-12-6` if you want short summaries.
(It rarely makes sense to start from `bart-large` unless you are a researching finetuning methods).
**Update 2018-07-18**
Datasets: `LegacySeq2SeqDataset` will be used for all tokenizers without a `prepare_seq2seq_batch` method. Otherwise, `Seq2SeqDataset` will be used.
Future work/help wanted: A new dataset to support multilingual tasks.
### Fine-tuning using Seq2SeqTrainer
To use `Seq2SeqTrainer` for fine-tuning you should use the `finetune_trainer.py` script. It subclasses `Trainer` to extend it for seq2seq training. Except the `Trainer`-related `TrainingArguments`, it shares the same argument names as that of `finetune.py` file. One notable difference is that calculating generative metrics (BLEU, ROUGE) is optional and is controlled using the `--predict_with_generate` argument.
With PyTorch 1.6+ it'll automatically use `native AMP` when `--fp16` is set.
To see all the possible command line options, run:
```bash
python finetune_trainer.py --help
```
For multi-gpu training use `torch.distributed.launch`, e.g. with 2 gpus:
```bash
torchrun --nproc_per_node=2 finetune_trainer.py ...
```
**At the moment, `Seq2SeqTrainer` does not support *with teacher* distillation.**
All `Seq2SeqTrainer`-based fine-tuning scripts are included in the `builtin_trainer` directory.
#### TPU Training
`Seq2SeqTrainer` supports TPU training with few caveats
1. As `generate` method does not work on TPU at the moment, `predict_with_generate` cannot be used. You should use `--prediction_loss_only` to only calculate loss, and do not set `--do_predict` and `--predict_with_generate`.
2. All sequences should be padded to be of equal length to avoid extremely slow training. (`finetune_trainer.py` does this automatically when running on TPU.)
We provide a very simple launcher script named `xla_spawn.py` that lets you run our example scripts on multiple TPU cores without any boilerplate. Just pass a `--num_cores` flag to this script, then your regular training script with its arguments (this is similar to the `torch.distributed.launch` helper for `torch.distributed`).
`builtin_trainer/finetune_tpu.sh` script provides minimal arguments needed for TPU training.
The following command fine-tunes `sshleifer/student_marian_en_ro_6_3` on TPU V3-8 and should complete one epoch in ~5-6 mins.
```bash
./builtin_trainer/train_distil_marian_enro_tpu.sh
```
## Evaluation Commands
To create summaries for each article in dataset, we use `run_eval.py`, here are a few commands that run eval for different tasks and models.
If 'translation' is in your task name, the computed metric will be BLEU. Otherwise, ROUGE will be used.
For t5, you need to specify --task translation_{src}_to_{tgt} as follows:
```bash
export DATA_DIR=wmt_en_ro
./run_eval.py google-t5/t5-base \
$DATA_DIR/val.source t5_val_generations.txt \
--reference_path $DATA_DIR/val.target \
--score_path enro_bleu.json \
--task translation_en_to_ro \
--n_obs 100 \
--device cuda \
--fp16 \
--bs 32
```
This command works for MBART, although the BLEU score is suspiciously low.
```bash
export DATA_DIR=wmt_en_ro
./run_eval.py facebook/mbart-large-en-ro $DATA_DIR/val.source mbart_val_generations.txt \
--reference_path $DATA_DIR/val.target \
--score_path enro_bleu.json \
--task translation \
--n_obs 100 \
--device cuda \
--fp16 \
--bs 32
```
Summarization (xsum will be very similar):
```bash
export DATA_DIR=cnn_dm
./run_eval.py sshleifer/distilbart-cnn-12-6 $DATA_DIR/val.source dbart_val_generations.txt \
--reference_path $DATA_DIR/val.target \
--score_path cnn_rouge.json \
--task summarization \
--n_obs 100 \
th 56 \
--fp16 \
--bs 32
```
### Multi-GPU Evaluation
here is a command to run xsum evaluation on 8 GPUS. It is more than linearly faster than run_eval.py in some cases
because it uses SortishSampler to minimize padding. You can also use it on 1 GPU. `data_dir` must have
`{type_path}.source` and `{type_path}.target`. Run `./run_distributed_eval.py --help` for all clargs.
```bash
torchrun --nproc_per_node=8 run_distributed_eval.py \
--model_name sshleifer/distilbart-large-xsum-12-3 \
--save_dir xsum_generations \
--data_dir xsum \
--fp16 # you can pass generate kwargs like num_beams here, just like run_eval.py
```
Contributions that implement this command for other distributed hardware setups are welcome!
#### Single-GPU Eval: Tips and Tricks
When using `run_eval.py`, the following features can be useful:
* if you running the script multiple times and want to make it easier to track what arguments produced that output, use `--dump-args`. Along with the results it will also dump any custom params that were passed to the script. For example if you used: `--num_beams 8 --early_stopping true`, the output will be:
```json
{'bleu': 26.887, 'n_obs': 10, 'runtime': 1, 'seconds_per_sample': 0.1, 'num_beams': 8, 'early_stopping': True}
```
`--info` is an additional argument available for the same purpose of tracking the conditions of the experiment. It's useful to pass things that weren't in the argument list, e.g. a language pair `--info "lang:en-ru"`. But also if you pass `--info` without a value it will fallback to the current date/time string, e.g. `2020-09-13 18:44:43`.
If using `--dump-args --info`, the output will be:
```json
{'bleu': 26.887, 'n_obs': 10, 'runtime': 1, 'seconds_per_sample': 0.1, 'num_beams': 8, 'early_stopping': True, 'info': '2020-09-13 18:44:43'}
```
If using `--dump-args --info "pair:en-ru chkpt=best`, the output will be:
```json
{'bleu': 26.887, 'n_obs': 10, 'runtime': 1, 'seconds_per_sample': 0.1, 'num_beams': 8, 'early_stopping': True, 'info': 'pair=en-ru chkpt=best'}
```
* if you need to perform a parametric search in order to find the best ones that lead to the highest BLEU score, let `run_eval_search.py` to do the searching for you.
The script accepts the exact same arguments as `run_eval.py`, plus an additional argument `--search`. The value of `--search` is parsed, reformatted and fed to ``run_eval.py`` as additional args.
The format for the `--search` value is a simple string with hparams and colon separated values to try, e.g.:
```
--search "num_beams=5:10 length_penalty=0.8:1.0:1.2 early_stopping=true:false"
```
which will generate `12` `(2*3*2)` searches for a product of each hparam. For example the example that was just used will invoke `run_eval.py` repeatedly with:
```
--num_beams 5 --length_penalty 0.8 --early_stopping true
--num_beams 5 --length_penalty 0.8 --early_stopping false
[...]
--num_beams 10 --length_penalty 1.2 --early_stopping false
```
On completion, this function prints a markdown table of the results sorted by the best BLEU score and the winning arguments.
```
bleu | num_beams | length_penalty | early_stopping
----- | --------- | -------------- | --------------
26.71 | 5 | 1.1 | 1
26.66 | 5 | 0.9 | 1
26.66 | 5 | 0.9 | 0
26.41 | 5 | 1.1 | 0
21.94 | 1 | 0.9 | 1
21.94 | 1 | 0.9 | 0
21.94 | 1 | 1.1 | 1
21.94 | 1 | 1.1 | 0
Best score args:
stas/wmt19-en-ru data/en-ru/val.source data/en-ru/test_translations.txt --reference_path data/en-ru/val.target --score_path data/en-ru/test_bleu.json --bs 8 --task translation --num_beams 5 --length_penalty 1.1 --early_stopping True
```
If you pass `--info "some experiment-specific info"` it will get printed before the results table - this is useful for scripting and multiple runs, so one can tell the different sets of results from each other.
### Contributing
- follow the standard contributing guidelines and code of conduct.
- add tests to `test_seq2seq_examples.py`
- To run only the seq2seq tests, you must be in the root of the repository and run:
```bash
pytest examples/seq2seq/
```
### Converting pytorch-lightning checkpoints
pytorch lightning ``-do_predict`` often fails, after you are done training, the best way to evaluate your model is to convert it.
This should be done for you, with a file called `{save_dir}/best_tfmr`.
If that file doesn't exist but you have a lightning `.ckpt` file, you can run
```bash
python convert_pl_checkpoint_to_hf.py PATH_TO_CKPT randomly_initialized_hf_model_path save_dir/best_tfmr
```
Then either `run_eval` or `run_distributed_eval` with `save_dir/best_tfmr` (see previous sections)
# Experimental Features
These features are harder to use and not always useful.
### Dynamic Batch Size for MT
`finetune.py` has a command line arg `--max_tokens_per_batch` that allows batches to be dynamically sized.
This feature can only be used:
- with fairseq installed
- on 1 GPU
- without sortish sampler
- after calling `./save_len_file.py $tok $data_dir`
For example,
```bash
./save_len_file.py Helsinki-NLP/opus-mt-en-ro wmt_en_ro
./dynamic_bs_example.sh --max_tokens_per_batch=2000 --output_dir benchmark_dynamic_bs
```
splits `wmt_en_ro/train` into 11,197 uneven length batches and can finish 1 epoch in 8 minutes on a v100.
For comparison,
```bash
./dynamic_bs_example.sh --sortish_sampler --train_batch_size 48
```
uses 12,723 batches of length 48 and takes slightly more time 9.5 minutes.
The feature is still experimental, because:
+ we can make it much more robust if we have memory mapped/preprocessed datasets.
+ The speedup over sortish sampler is not that large at the moment.

mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data | mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data/wmt_en_ro/val.source | Brazil's Former Presidential Chief-of-Staff to Stand Trial A federal judge on Tuesday accepted the charges filed against Brazil's former presidential chief of staff for his alleged involvement in a massive corruption scheme at state-owned oil company Petrobras. The federal prosecutor's office said Jose Dirceu will face trial on the corruption, racketeering and money laundering charges filed earlier this month. Fourteen other people will also be tried, including Joao Vaccari Neto, the former treasurer of Brazil's governing Workers' Party and Renato de Souza Duque, Petrobras' former head of corporate services.
Dirceu is the most senior member of the ruling Workers' Party to be taken into custody in connection with the scheme. Dirceu served as former President Luiz Inacio Lula da Silva's chief of staff between 2003 and 2005. He was arrested early August in his home, where he already was under house arrest serving an 11-year sentence for his involvement in a cash-for-votes scheme in Congress more than 10 years ago. Prosecutors have said that Dirceu masterminded the kickback scheme at Petrobras, accepted bribes while in office and continued to receive payments from contractors after he was jailed in late 2013 for the vote-buying scandal.
According to prosecutors, the scheme at Petrobras involved roughly $2 billion in bribes and other illegal funds. Some of that money was allegedly funneled back to campaign coffers of the ruling party and its allies. It also allegedly included the payment of bribes to Petrobras executives in return for inflated contracts. 'Miraculous' recovery for Peshawar massacre schoolboy A teenager paralysed after being shot four times in Pakistan's deadliest terror attack has made a "miraculous" recovery following treatment in the UK. Muhammad Ibrahim Khan, 13, had been told by doctors in Pakistan that he would never walk again.
At least 140 people, mostly children, were killed when gunmen stormed Peshawar's Army Public School last December. Muhammad, who arrived in London last month for surgery, is being discharged from hospital later. Exactly nine months ago, on an ordinary Tuesday morning, Muhammad sat in his first aid class listening to his teachers intently. At the same time seven gunmen disguised in security uniforms were entering the Army Public School. They were strapped with explosives and had one simple mission in mind: Kill every man, woman and child they came across. "I can't forget what happened that day," Muhammad says with a severe stare.
We were sitting in the auditorium, we were asking questions... and then we heard heavy gunfire outside. The terrorists moved inside and they started killing - our teacher was burned alive. Muhammad described pulling four other pupils out of the auditorium as the carnage unfolded. He said he then heard his friend, Hamza calling to him. He said, 'oh brother save me'. I held his hand. That's when I was shot in the back, and he was shot in the head. Most of the people killed in the attack were pupils Hamza died in Muhammad's arms. Muhammad recalled blacking out after that, and the next thing he knew he was in a hospital bed, paralysed from the waist down.
Doctors in Peshawar in northern Pakistan, and then Rawalpindi, close to the capital, told his family there was no treatment, and he would never walk again. "Seeing him I felt like my soul had left my body," says Muhammad's father, Sher Khan Those nine months were the hardest in my life. But Mr Khan and his wife, Sherbano, refused to believe that their cricket-mad son would never be able to use his legs again. They campaigned, and appealed for help on Pakistani TV, gaining the support of high profile people such as cricketer turned politician Imran Khan.
Finally, they were able to raise the funds to bring Muhammad to the UK and provide him with treatment at London's private Harley Street Clinic. Consultant neurosurgeon Irfan Malik described Muhammad as "terrified" when he first arrived at the hospital. "He'd spent the last [few] months lying on a bed, unable to move side to side," says Mr Malik. He was weak, he had a pressure sore on his back. He wasn't in great shape. A vertebra at the base of Muhammad's spine was destroyed Muhammad was shot in his shoulder, his hip, and his back during the attack, damaging his lower spine - leading to paralysis.
But during six hours of surgery, Mr Malik and his team were able to reattach nerve endings and reconstruct the damaged part of the spine. Even Mr Malik was surprised at what happened next. Exactly one week after the surgery Muhammad stood up and started taking steps and walking. We were not expecting to get that sort of excellent result. That was miraculous," he says. Less than two weeks after his operation, Muhammad is ready to leave hospital and start the long road to recovery. Muhammad has defied the odds and started to walk again He says he wants to build his strength and continue his education in the UK. But he says he is determined to return to Pakistan, join the army and help fight terrorism.
"I feel like I have a second chance at life," he says as he shows off pictures he's drawn of guns scribbled out next to school books and pens Muhammad grows physically stronger every day but the psychological trauma he continues to endure is unimaginable. "My anger is not diminishing" he says. In my school little kids were killed. What was their crime? His mother, wiping a tear from her eye, caressed his head and said: "I can see my son walking again." He'll be able to get on with his normal life. 'Super Voice' 4G service from Three offers better signal Three is making use of a lower frequency 4G spectrum that can travel more widely
Mobile phone provider Three has launched a UK service it says will improve reception inside buildings and in rural black spots. Its 4G Super Voice enables customers to make calls and send texts using a lower frequency spectrum. Other networks are looking into introducing the technology, known as Voice Over Long-Term Evolution (VoLTE). It currently works on only the Samsung Galaxy S5, but recent iPhone handsets will be added in the coming months. Three said up to 5.5 million customers would have access to the service by 2017.
Chief technology officer Bryn Jones said: "By the end of the year, one million of our customers will have access to better indoor coverage and be able to use their phones in more places than ever before." Stars prepare for panto season Pantomime season is big business for theatres up and down the UK, with many getting ready for this year's season now. Some of the biggest names in showbusiness now take part in the yuletide theatre. Matthew Kelly and Hayley Mills will be appearing in Cinderella - one as an ugly sister, the other as fairy godmother. They reveal their panto secrets to BBC Breakfast. Steven Wilson: 'If I don't do anything, I feel this creeping guilt'
Steven Wilson was recently the big winner at the Progressive Music Awards Steven Wilson is often dubbed the hardest working musician in the world of progressive rock. The multi-talented musician won three prizes at this month's Progressive Music Awards in London, including album of the year for Hand. The Guardian's five-star review called it "a smart, soulful and immersive work of art." Since the 1980s, Wilson has been the driving force in a number of musical projects, the best known of which is the rock band Porcupine Tree. Now, ahead of two sell-out shows at the Royal Albert Hall, Wilson is releasing a vinyl-only double LP, Transience, to showcase the "more accessible" side of his solo output.
He tells the BBC about his love of vinyl, his busy schedule and explains how comic actor Matt Berry came to be his support act. What does vinyl mean to you? I grew up at the very tail end of the vinyl era, and at the time, I remember, we couldn't wait for CD to come along because vinyl was so frustrating. You would buy the record, take it home, and it would have a scratch, and you would have to take it back again. I love CDs, and for some kinds of music - classical for example - it is better than vinyl. But the problem with the CD and digital downloads is that there's nothing you can really cherish or treasure. Owning vinyl is like having a beautiful painting hanging in your living room.
It's something you can hold, pore over the lyrics and immerse yourself in the art work. I thought it was just a nostalgic thing, but it can't be if kids too young to remember vinyl are enjoying that kind of experience. Do you have a piece of vinyl that you treasure? The truth is I got rid of 100% of my vinyl in the 90s. All the vinyl I have is re-bought. I started off from the perspective that I wanted to recreate the collection I had when I was 15, but it's gone beyond that. The first record which I persuaded my parents to buy for me was Electric Light Orchestra's Out of the Blue.
If I still had my original copy, it would have sentimental value, but, alas, it's in a charity shop somewhere. Steven Wilson hopes the album will be a doorway for potential new fans Why release your new compilation Transience on vinyl? It was originally conceived as an idea for Record Store Day, but we missed the boat on that. My record company had suggested I put together some of my shorter, more accessible songs. I got a bit obsessed by the idea to make something like "an introduction to Steven Wilson," and I was committed to it being a vinyl-only release. Anyone who buys the vinyl does also get a high-resolution download.
Do you have a concern that the album won't show your work in a true light? | 0 |

mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data | mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data/wmt_en_ro/test.source | UN Chief Says There Is No Military Solution in Syria Secretary-General Ban Ki-moon says his response to Russia's stepped up military support for Syria is that "there is no military solution" to the nearly five-year conflict and more weapons will only worsen the violence and misery for millions of people. The U.N. chief again urged all parties, including the divided U.N. Security Council, to unite and support inclusive negotiations to find a political solution. Ban told a news conference Wednesday that he plans to meet with foreign ministers of the five permanent council nations - the U.S., Russia, China, Britain and France - on the sidelines of the General Assembly's ministerial session later this month to discuss Syria.
He expressed regret that divisions in the council and among the Syrian people and regional powers "made this situation unsolvable." Ban urged the five permanent members to show the solidarity and unity they did in achieving an Iran nuclear deal in addressing the Syria crisis. 8 Poll Numbers That Show Donald Trump Is For Real Some have tried to label him a flip-flopper. Others have dismissed him as a joke. And some are holding out for an implosion. But no matter how some Republicans are trying to drag Donald Trump down from atop the polls, it hasn't worked (yet).
Ten of the last 11 national polls have shown Donald Trump's lead at double digits, and some are starting to ask seriously what it means for the real estate mogul's nomination chances. Of course, it's still early in the election cycle. None of this is to say that Trump is likely to win the Republican nomination. Pundits point out that at this time in 2011, Rick Perry's lead was giving way to a rising Herman Cain, neither of whom won even one state in the nomination process. And there are many reasons he would struggle in a general election. But outside groups like Jeb Bush's Super PAC and the economic conservative group Club for Growth are recognizing Trump's staying power and beginning to unload their dollars to topple him.
Here are some recent poll numbers that suggest that the real estate mogul isn't just a passing phase: Trump's favorability ratings have turned 180 degrees. Right before Donald Trump announced his candidacy in mid-June, a Monmouth University poll showed only two in 10 Republicans had a positive view of the real estate mogul. By mid-July, it was 40 percent. In early August, it was 52 percent. Now, six in 10 Republicans have a favorable view of Donald Trump. Roughly three in 10 say they have a negative view. And these numbers hold up in early states. A Quinnipiac poll in Iowa last week found that 60 percent of Republicans there had a favorable view of Trump.
Two-thirds of GOP voters would be happy with Trump as the nominee. In a CNN/ORC poll last week, 67 percent of Republicans said they would be either "enthusiastic" or "satisfied" if Trump were the nominee. Only two in 10 say they would be "upset" if he were the nominee. Only Ben Carson generates roughly the same level of enthusiasm as Trump (43 percent say they would be "enthusiastic" vs. 40 percent who say the same of Trump). The next closest in enthusiasm? Marco Rubio with only 21 percent.
On the flip side, 47 percent of Republican voters say they would be "dissatisfied" or "upset" if establishment favorite Jeb Bush becomes the nominee. A majority of Republicans don't see Trump's temperament as a problem. While Donald Trump has been widely criticized for his bombast and insults, 52 percent of leaned Republican voters nationwide think that the real estate mogul has the right temperament to be president, according to Monday's ABC News/Washington Post poll. The same number holds in the first-in-the-nation caucus state of Iowa, where the same 52 percent of Republicans think he has the personality to be commander in chief, according to Quinnipiac last week.
Still, 44 percent think he doesn't have the personality to serve effectively, and almost six in 10 independents say his temperament does not belong in the White House, according to ABC/Post. Republican voters are getting used to the idea. When they put on their pundit hats, Republican voters think Trump is for real. When asked who is most likely to win the GOP nomination, four in 10 said Trump was the best bet, according to a CNN/ORC poll out last week. That's a change from when four in 10 placed their money on Jeb Bush in late July. Full disclosure: GOP voters haven't had the clearest crystal ball in the past.
At this time last cycle, four in 10 Republicans picked Rick Perry to win the nomination, vs. only 28 percent for eventual nominee Mitt Romney. Still, it shows that a plurality of GOP voters see Trump's campaign as plausible. Even if Republicans rallied around another candidate, Trump still beats almost everyone. Some pundits point out that the splintered field is likely contributing to Trump's lead, while anti-Trump support is be spread diffusely among more than a dozen other candidates. But a Monmouth University poll in early September shows that, in a hypothetical head-to-head matchup between Trump and most other Republican candidates, Trump almost always garners majority support.
He leads Carly Fiorina by 13 points, Marco Rubio by 14 points, Walker by 15 points, Jeb Bush by 19 points, and, finally, Rand Paul, John Kasich and Chris Christie by 33 points each. He's in a dead heat with Ted Cruz. The only candidate who beats him? Ben Carson would lead the businessman by a wide 19 points in a hypothetical head-to-head. A bare majority of Donald Trump's supporters say they've made up their minds. A new CBS/NYT poll out on Tuesday shows that just more than half of voters who support Trump say they have locked in their votes. Obviously, a lot can happen to change that, and no one can really say they would never change their mind.
46 percent said they are leaving the door open to switching candidates. Still, Trump's strongest competition at the moment is from fellow outsider neurosurgeon Ben Carson, but voters who say they have made up their minds are twice as likely to go for Trump. Six in 10 Republicans say they agree with Trump on immigration. Even since Donald Trump called immigrants from Mexico "rapists" in his campaign announcement speech two months ago, immigration has been front and center in the 2016 conversation. Some are worried that Trump's bombast will drive crucial Hispanic voters away from the Republican Party and damage rebranding efforts.
But according to Monday's new ABC/Post poll, six in 10 Republicans say they agree with Trump on immigration issues. So as long as immigration remains in the spotlight, it seems Donald Trump will remain too. Frustration with government is climbing to new highs. Donald Trump and Ben Carson now account for roughly half of the support from Republican voters, largely due to their outsider status. Six in 10 Republicans in Monday's new ABC/Post poll say they want a political outsider over someone with government experience. And they are angry at Washington, too.
A Des Moines Register/Bloomberg poll in Iowa from two weeks ago shows that three in four Iowa Republicans are frustrated with Republicans in Congress, with 54 percent "unsatisfied" and 21 percent "mad as hell." Jeremy Corbyn to make debut at Prime Minister's Questions Since his election, Mr Corbyn's debut at PMQs has been keenly awaited New Labour leader Jeremy Corbyn is to make his debut at Prime Minister's Questions later, taking on David Cameron for the first time.
Mr Corbyn will rise to ask the first of his six allotted questions shortly after midday, with his performance likely to be closely scrutinised by the media and Labour MPs. He has called for "less theatre and more facts" at the weekly showpiece. He has also said he could skip some sessions, leaving them to colleagues. The encounter will be the first parliamentary test of Mr Corbyn's leadership, coming after his appointment of a shadow cabinet and his speech to the TUC annual congress on Tuesday.
Meanwhile, the Labour leader's decision to stand in silence during the singing of the national anthem at a service on Tuesday to mark the 75th anniversary of the Battle of Britain has attracted criticism from a number of Tory MPs and is the focus of several front page stories in the newspapers. Mr Corbyn's decision not to sing the national anthem has attracted attention A spokesman for Mr Corbyn said he had "stood in respectful silence" and did recognise the "heroism of the Royal Air Force in the Battle of Britain."
But a member of Mr Corbyn's shadow cabinet, Owen Smith, told BBC Two's Newsnight programme he would have advised the Labour leader to sing the national anthem "irrespective" of his belief that the monarchy should be abolished. Nearly a dozen shadow ministers have refused to serve in Mr Corbyn's top team, citing differences over the economy, defence and foreign affairs, while less than a sixth of the parliamentary party originally backed him as leader. BBC political correspondent Robin Brant says policy differences are also "stacking up" within Labour following Mr Corbyn's appointment over its position on the European Union and the government's cap on benefits.
Mr Corbyn told the TUC conference Labour was putting forward amendments to remove the whole idea of a cap altogether. Hours later Mr Smith, the shadow work and pensions secretary, said the party was "very clear" that it was only opposing government plans to reduce the level of cap from £26,000 to £23,000. Mr Corbyn will be the fifth Labour leader that David Cameron has faced across the despatch box over the past decade since he became Tory leader. The Labour leader, who has promised a different approach to politics, says he has "crowd sourced" ideas for questions to ask Mr Cameron and has been given more than 30,000 suggestions.
The Islington North MP has said PMQs is too confrontational and that he will refrain from both "repartee" and trading barbs, instead vowing to focus on serious issues such as poverty, inequality and the challenges facing young people. Mr Corbyn has said that Angela Eagle, the shadow business secretary, will deputise for him at PMQs when he does not attend - for instance when Mr Cameron is travelling abroad. He has also floated the idea of allowing other colleagues to take the floor on occasion, saying he had approached the Commons Speaker John Bercow to discuss the issue.
When he became leader in 2005, Mr Cameron said he wanted to move away from the "Punch and Judy" style of politics often associated with PMQs but admitted some years later that he had failed. Since it was first televised in 1990, PMQs has been seen as a key barometer of a leader's judgement, their command of the Commons and their standing among their fellow MPs although critics have argued it has become a caricature and is in need of far-reaching reforms. 'Shot in Joburg': Homeless youth trained as photographers Downtown Johannesburg is a tough place to be homeless.
But one group of former street children have found a way to learn a skill and make a living. "I was shot in Joburg" is a non-profit studio that teaches homeless youngsters how to take photographs of their neighbourhood and make a profit from it. BBC News went to meet one of the project's first graduates. JD Sports boss says higher wages could hurt expansion JD Sports Executive Chairman Peter Cowgill says a higher minimum wage for UK workers could mean "more spending power in the pockets of potential consumers." But that spending power is unlikely to outweigh the higher labour costs at his firm, he says.
The costs could hit JD Sports' expansion plans, he added, which could mean fewer extra jobs. Thanasi Kokkinakis backed by Tennis Australia president Steve Healy Thanasi Kokkinakis deserves kudos rather than criticism for his behaviour. Thanasi Kokkinakis has been the collateral damage in the recent storm around his friend Nick Kyrgios and deserves kudos rather than criticism for his own behaviour, according to Tennis Australia president Steve Healy. | 0 |
mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data | mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data/wmt_en_ro/val.target | Fostul șef al cabinetului prezidențial brazilian este adus în fața instanței Marți, un judecător federal a acceptat acuzațiile aduse împotriva fostului șef al cabinetului prezidențial brazilian pentru presupusa implicare a acestuia într-o schemă masivă de corupție privind compania petrolieră de stat Petrobras. Biroul procurorului federal a declarat că Jose Dirceu va fi trimis în judecată pentru acuzațiile de corupție, înșelătorie și spălare de bani aduse în această lună. Alte paisprezece persoane vor fi judecate, printre acestea numărându-se Joao Vaccari Neto, fostul trezorier al Partidului Muncitorilor, aflat la putere în Brazilia, și Renato de Souza Duque, fostul președinte al serviciilor pentru întreprinderi ale Petrobras.
Dirceu este cel mai vechi membru al Partidului Muncitorilor aflat la guvernare luat în custodie pentru legăturile cu această schemă. Dirceu a servit ca șef de cabinet al fostului președinte Luiz Inacio Lula da Silva între 2003 și 2005. A fost arestat la începutul lui august de acasă, unde deja se afla sub arest la domiciliu, cu o pedeapsă de 11 ani pentru implicarea într-o schemă de cumpărare a voturilor în Congres cu peste 10 ani în urmă. Procurorii au declarat că Dirceu a dezvoltat schema de luare de mită de la Petrobras, a acceptat mită în timp ce se afla în funcție și a continuat să primească plăți de la antreprenori după ce a fost închis la sfârșitul lui 2013 pentru scandalul voturilor cumpărate.
Conform procurorilor, schema de la Petrobras a implicat aproximativ 2 miliarde de dolari sub formă de mită și alte fonduri ilegale. O parte din acei bani s-ar fi întors în fondul de campanie al partidului aflat la guvernare și al aliaților acestora. De asemenea, ar fi inclus mită către directorii Petrobras în schimbul unor contracte umflate. Recuperarea „miraculoasă” a unui elev supraviețuitor al masacrului de la Peshawar Un adolescent paralizat după ce fusese împușcat de patru ori în cel mai cumplit atac terorist din Pakistan a reușit o recuperare „miraculoasă” după ce a urmat un tratament în Regatul Unit. Lui Mohamed Ibrahim Khan, în vârstă de 13 ani, doctorii din Pakistan îi spuseseră că nu va mai putea să meargă niciodată.
Cel puțin 140 de persoane, majoritatea copii, au fost ucise când bărbați înarmați au atacat școala publică a armatei din Peshawar în luna decembrie a anului trecut. Mohamed, care a sosit la Londra luna trecută pentru operație, va fi externat mai târziu din spital. Exact cu nouă luni în urmă, într-o dimineață obișnuită de marți, Mohamed stătea la ora de primul ajutor și își asculta atent profesorii. Chiar atunci, șapte bărbați înarmați deghizați în uniformele agenților de pază intrau în școala publică a armatei. Purtau centuri cu explozivi și aveau de îndeplinit o misiune simplă: să îi ucidă pe toți bărbații, femeile și copiii care le ieșeau în cale. „Nu pot uita ce s-a întâmplat în acea zi”, spune Mohamed cu o privire aspră.
Stăteam în amfiteatru, puneam întrebări... apoi am auzit focuri de armă afară. Teroriștii au intrat înăuntru și au început să ucidă. Profesorul nostru a fost ars de viu. Mohamed descrie cum a scos patru elevi din amfiteatru în timp ce se desfășura carnagiul. Apoi spune că și-a auzit prietenul, pe Hamza, strigându-l. Spunea „oh, frate, salvează-mă”. L-am ținut de mână. Atunci eu am fost împușcat în spate, iar el în cap. Cei mai mulți dintre cei uciși în atac erau elevi Hamza a murit în brațele lui Mohamed. Mohamed își amintește că imediat după asta a leșinat și că următorul lucru pe care l-a știut a fost că se afla pe un pat de spital, paralizat de la brâu în jos.
Doctorii din Peshawar din nordul Pakistanului, apoi cei din Rawalpindi, aproape de capitală, i-au spus familiei sale că nu exista tratament și că nu va mai putea merge niciodată. „Când l-am văzut, am simțit cum îmi iese sufletul”, spune Sher Khan, tatăl lui Mohamed. Acele nouă luni au fost cele mai grele din viața mea. Însă Khan și soția lui, Sherbano, au refuzat să creadă că fiul lor atât de pasionat de crichet nu-și va mai putea folosi vreodată picioarele. Au făcut o campanie și au cerut ajutor de la televiziunea pakistaneză, atrăgând sprijinul unor oameni faimoși precum Imran Khan, jucător de crichet devenit politician.
Într-un final, au reușit să strângă fonduri pentru a-l duce pe Mohamed în Regatul Unit și a-i oferi tratament la clinica privată Harley Street din Londra. Neurochirurgul consultant Irfan Malik l-a descris pe Mohamed drept „înspăimântat” când acesta a ajuns la spital. „Își petrecuse ultimele [câteva] luni zăcând în pat, fără să se poată mișca de pe o parte pe alta, spune Malik. Era slăbit, se pusese multă presiune pe spatele lui. Nu era într-o formă prea bună. O vertebră de la baza coloanei vertebrale a lui Mohamed fusese distrusă Mohamed fusese împușcat în umăr, în șold și în spate în timpul atacului, iar coloana vertebrală inferioară îi fusese distrusă, ducând la paralizie.
Însă, în timpul unei operații care a durat șase ore, Malik și echipa lui au reușit să lege din nou terminațiile nervoase și să reconstruiască partea distrusă a coloanei. Chiar și Malik a fost surprins de ceea ce s-a întâmplat în continuare. Exact la o săptămână după operație, Mohamed s-a ridicat și a început să facă pași și să meargă. Nu ne așteptam la un rezultat atât de bun. A fost un miracol”, spune acesta. În mai puțin de două săptămâni de la operație, Mohamed este gata să părăsească spitalul și să înceapă procesul lung de recuperare. Mohamed a sfidat soarta și a început să meargă din nou Vrea să devină puternic și să își continue studiile în Regatul Unit. Însă este hotărât să revină în Pakistan, să se înroleze în armată și să lupte împotriva terorismului.
„Simt că am încă o șansă la viață” spune el, arătând imaginile cu arme desenate de el lângă manuale școlare și stilouri Fizic, Mohamed devine tot mai puternic în fiecare zi, însă trauma psihologică prin care trece și acum este de neimaginat. „Furia mea nu a scăzut”, mărturisește el. În școala mea au fost uciși copii mici. Ce crimă au comis ei? Mama lui își șterge o lacrimă, îl mângâie pe creștet și spune: „Îmi văd fiul mergând din nou”. Va putea să-și continue firesc viața. Serviciul 4G „Super Voice” de la Three oferă semnal mai bun Three folosește un spectru 4G cu o frecvență mai joasă, care poate acoperi o zonă mai extinsă
Furnizorul de telefonie mobilă Three a lansat în Regatul Unit un serviciu despre care spune că va îmbunătăți recepția în interiorul clădirilor și în zonele rurale fără semnal. Serviciul 4G Super Voice le permite clienților să efectueze apeluri și să trimită mesaje text folosind un spectru cu o frecvență mai joasă. Și alte rețele intenționează să introducă aceeași tehnologie, cunoscută ca „Voice Over Long-Term Evolution (VoLTE)”. Aceasta funcționează momentan doar cu Samsung Galaxy S5, însă telefoanele iPhone recente vor beneficia de ea în lunile următoare. Three menționează că până la 5,5 milioane de clienți vor avea acces la serviciu până în 2017.
Responsabilul șef pentru tehnologie, Bryn Jones a declarat: „Până la sfârșitul anului, un milion dintre clienții noștri vor avea acces la o acoperire mai bună în interior și își vor putea folosi telefoanele în mai multe locuri ca până acum”. Vedetele se pregătesc pentru stagiunea de pantomimă Stagiunea de pantomimă este foarte importantă pentru teatrele din tot Regatul Unit, multe dintre ele pregătindu-se acum pentru stagiunea din acest an. Acum, la teatrul de Crăciun participă unele dintre numele cele mai mari din showbusiness. Matthew Kelly și Hayley Mills vor apărea în Cenușăreasa - primul în rolul uneia dintre surorile rele, iar a doua în rolul zânei. Aceștia dezvăluie secretele pantomimei lor la BBC Breakfast. Steven Wilson: „Dacă nu fac nimic, mă simt vinovat”
Steven Wilson a fost desemnat recent drept marele câștigător al Progressive Music Awards Steven Wilson a fost numit de multe ori drept cel mai muncitor muzician din lumea rockului progresiv. Talentatul muzician a câștigat trei premii la Progressive Music Awards, care a avut loc luna aceasta la Londra, printre care și premiul pentru cel mai bun album al anului pentru Hand. În recenzia sa de cinci stele, The Guardian a numit albumul „o operă de artă inteligentă, expresivă și captivantă”. Încă din anii 1980, Wilson este motorul mai multor proiecte muzicale, cel mai cunoscut dintre acestea fiind trupa de rock Porcupine Tree. Acum, înainte de două spectacole cu casa închisă la Royal Albert Hall, Wilson lansează un dublu LP doar în format vinil, Transience, pentru a arăta latura „mai accesibilă” a activității sale solo.
A povestit pentru BBC despre dragostea lui pentru viniluri și despre programul său încărcat și a explicat cum a ajuns actorul de comedie Matt Berry să îi deschidă spectacolele. Ce înseamnă vinil pentru tine? Am crescut chiar în perioada de sfârșit a erei vinilurilor și îmi amintesc că atunci abia așteptam apariția CD-ului, căci vinilul era atât de enervant. Cumpărai un disc, mergeai cu el acasă, avea o zgârietură și trebuia să îl aduci înapoi. Iubesc CD-urile, iar pentru anumite tipuri de muzică, de exemplu cea clasică, sunt mai bune decât vinilurile. Însă problema cu CD-urile și cu descărcările digitale este aceea că nu mai există nimic pe care să îl prețuiești cu adevărat. Să ai un vinil e ca și cum ai avea un tablou frumos agățat în sufragerie.
E ceva ce poți ține în mână, în timp ce te lași absorbit de versuri și copleșit de actul artistic. Am crezut că e doar o chestie nostalgică, însă nu are cum să fie așa dacă unor puști prea tineri să-și amintească de viniluri le place acest gen de experiență. Ai vreun vinil la care ții în mod special? Recunosc că am scăpat de toate vinilurile în anii '90. Toate vinilurile pe care le am sunt cumpărate din nou. Am pornit de la ideea de a reface colecția pe care o aveam la 15 ani, însă am trecut de limita aceea. Primul disc pe care mi-am convins părinții să mi-l cumpere a fost Out of the Blue de la Electric Light Orchestra.
Dacă aș mai fi avut încă exemplarul inițial, acesta ar fi avut valoare sentimentală, însă, din păcate, se află pe undeva printr-un magazin de caritate. Steven Wilson speră că albumul va fi o poartă către posibili fani noi De ce ți-ai lansat noua compilație Transience pe vinil? Aceasta a fost concepută inițial ca idee pentru Ziua magazinelor de discuri, însă am ratat ocazia. Casa mea de discuri sugerase să adun câteva dintre melodiile mele mai scurte și mai accesibile. Am ajuns să fiu ușor obsedat de ideea de a face ceva gen „introducere în muzica lui Steven Wilson” și am ținut neapărat ca proiectul să fie lansat doar pe vinil. Cine cumpără vinilul primește, de asemenea, și o variantă descărcată la rezoluție înaltă.
Ești îngrijorat că albumul nu va arăta muzica ta în adevărata ei lumină? | 0 |
mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data | mavonic_private_repos/transformers/examples/legacy/seq2seq/test_data/wmt_en_ro/test.target | Șeful ONU declară că nu există soluții militare în Siria Secretarul General Ban Ki-moon afirmă că răspunsul său la suportul militar al Rusiei pentru Siria este că „nu există o soluție militară” la conflictul care durează de aproape cinci ani iar mai multe arme nu ar face decât să agraveze violența și suferința a milioane de oameni. Șeful ONU a solicitat din nou tuturor părților, inclusiv Consiliului de securitate ONU divizat să se unifice și să susțină negocierile pentru a găsi o soluție politică. Ban a declarat miercuri în cadrul unei conferințe că intenționează să se întâlnească luna aceasta cu miniștrii de externe din cinci țări permanent prezente în consiliu - SUA, Rusia, China, Anglia și Franța - pe marginea sesiunii ministeriale a Adunării Generale pentru a discuta despre Siria.
Ban și-a exprimat regretul că divizările în consiliu și între poporul sirian și puterile regionale „au făcut această situație de nerezolvat”. Ban le-a cerut celor cinci membri permanenți să dea dovadă de solidaritatea și unitatea arătate atunci când au reușit să încheie un acord referitor la armele nucleare ale Iranului, abordând astfel criza din Siria. 8 cifre din sondaje care arată că Donald Trump are șanse reale Unii au încercat să îl eticheteze ca politician „flip-flop”. Alții l-au numit o glumă. Iar alții așteaptă implozia. Însă indiferent de modul în care unii republicani încearcă să îl dărâme pe Donald Trump din vârful sondajelor, nu a funcționat (încă).
Zece din ultimele 11 sondaje naționale au arătat că Donald Trump conduce cu un procent din două cifre iar unele voci încep să se întrebe serios ce înseamnă acest lucru pentru șansele de numire ale mogulului imobiliar. Desigur, este încă prematur. Nimic din toate acestea nu spune că Trump va câștiga cursa pentru nominalizarea republicanilor. Pundits arată că, în aceeași perioadă a anului 2011, avansul lui Rick Perry îi făcea loc lui Herman Cain în sondaje, dar niciunul dintre ei nu a câștigat în vreun stat în cursa de nominalizare. Iar motivele pentru care s-ar lupta din greu la alegerile generale sunt numeroase. Însă grupurile din exterior precum Super PAC al lui Jeb Bush și grupul conservator economic Club for Growth admit puterea lui Trump și încep să îl susțină cu bani.
În continuare vă prezentăm câteva cifre din sondaje recente care sugerează că mogulul imobiliar nu este doar ceva trecător: Cifrele care indică susținerea față de Trump s-au întors la 180 grade. Chiar înainte ca Donald Trump să își anunțe candidatura, la mijlocul lui iunie, un sondaj realizat de Universitatea din Monmouth arăta că doar doi din 10 republicani aveau o părere pozitivă despre mogulul imobiliar. Până la mijlocul lui iulie, procentul a urcat la 40%. La începutul lui august, era 52%. În prezent, șase din 10 republicani au o părere favorabilă despre Donald Trump. Aproximativ trei din 10 declară că au o părere negativă. Aceste cifre se mențin. Un sondaj realizat săptămâna trecută de Quinnipiac în Iowa a concluzionat că 60% dintre republicanii din regiune au o părere favorabilă despre Trump.
Două treimi dintre alegătorii GOP ar fi fericiți dacă Trump ar câștiga cursa pentru nominalizare. Într-un sondaj realizat săptămâna trecută de CNN/ORC, 67% dintre republicani au declarat că ar fi „entuziasmați” sau „mulțumiți” dacă Trump ar câștiga cursa pentru nominalizare. Doar doi din 10 declară că ar fi „supărați” dacă Trump ar câștiga cursa pentru nominalizare. Doar Ben Carson generează aproximativ același nivel de entuziasm ca Trump (43% declară că ar fi „entuziasmați” față de 40% care declară același lucru despre Trump). Cel mai aproape în ceea ce privește entuziasmul? Marco Rubio, cu doar 21%.
De partea cealaltă, 47% dintre alegătorii republicani afirmă că ar fi „nemulțumiți” sau „supărați” dacă favoritul Jeb Bush câștigă cursa pentru nominalizare. Majoritatea republicanilor nu consideră temperamentul lui Trump o problemă. Deși Donald Trump a fost puternic criticat pentru insultele aduse și stilul său bombastic, 52% dintre alegătorii republicani la nivel național consideră că mogulul imobiliar are temperamentul potrivit pentru a fi președinte, conform sondajului realizat luni de ABC News/Washington Post. Regăsim aceleași cifre în statul Iowa, unde tot 52% dintre republicani cred că Trump are personalitatea potrivită pentru a fi conducător, conform sondajului realizat săptămâna trecută de Quinnipiac.
Totuși, 44% sunt de părere că nu are personalitatea necesară pentru a acționa eficient și aproape șase din 10 independenți afirmă că temperamentul său nu are ce căuta la Casa Albă, conform ABC/Post. Alegătorii republicani se obișnuiesc cu ideea. Atunci când iau atitudinea de intelectuali, alegătorii republicani consideră că Trump este autentic. Conform unui sondaj realizat săptămâna trecută de CNN/ORC, la întrebarea cine are cele mai multe șanse să câștige cursa pentru nominalizare GOP, patru din 10 au declarat că Trump. Situația s-a schimbat față de finalul lui iulie, când patru din 10 ar fi pariat pe Jeb Bush. Informare completă: în trecut, alegătorii GOP nu au citit foarte bine viitorul.
În aceeași perioadă a ultimelor alegeri, patru din 10 republicani l-au ales pe Rick Perry în cursa pentru nominalizare, față de doar 28% pentru Mitt Romney. Însă, aceste cifre arată că majoritatea alegătorilor GOP consideră plauzibilă campania lui Trump. Chiar dacă republicanii sau repliat spre un alt candidat. Trump încă se află în fruntea tuturor. Unele voci spun că situația divizată va contribui probabil la victoria lui Trump, în timp ce susținerea contra lui Trump se va împărți la mai mult de doisprezece candidați. Însă un sondaj derulat la începutul lui septembrie de Universitatea din Monmouth arată că, în situația ipotetică a unei colaborări între Trump și majoritatea celorlalți candidați republicani, aproape întotdeauna Trump va beneficia de susținerea majoritară.
Trump se află la distanță de 13 puncte de Carly Fiorina, la 14 puncte de Marco Rubio, la 15 puncte de Walker, la 19 puncte de Jeb Bush și, în cele din urmă, la câte 33 de puncte față de Rand Paul, John Kasich și Chris Christie. Este aproape la egalitate cu Ted Cruz. Singurul candidat care îl învinge? Ben Carson l-ar învinge pe omul de afaceri cu 19 puncte într-o confruntare ipotetică de unu la unu. Majoritatea susținătorilor lui Donald Trump declară că s-au decis. Un nou sondaj realizat marți de CBS/NYT arată că peste jumătate dintre alegătorii care îl susțin pe Trump declară că nu își schimbă opțiunea de vot. Evident, se pot întâmpla multe în acest sens și nimeni nu poate spune că aceștia nu se vor răzgândi niciodată.
46% afirmă că lasă portița deschisă posibilității de a-și schimba opțiunea. Cu toate acestea, cel mai important adversar al lui Trump este în prezent neurochirurgul Ben Carson, însă este de două ori mai probabil ca alegătorii care declară că s-au decis să voteze cu Trump. Șase din 10 republicani afirmă că sunt de acord cu Trump în problema imigrării. De când Donald Trump i-a numit pe imigranții din Mexic „violatori” în discursul de deschidere a campaniei sale, în urmă cu două luni, imigrarea a fost subiectul central în campania pentru 2016. Unii sunt îngrijorați că stilul bombastic al lui Trump va duce la o scindare între alegătorii hispanici importanți și Partidul Republican și va prejudicia eforturile de rebranding.
Însă, conform sondajului realizat luni de ABC/Post, șase din 10 republicani afirmă că sunt de acord cu Trump în problema imigrării. Așa că, se pare că atâta timp cât problema imigrării rămâne în lumina reflectoarelor, la fel va rămâne și Doland Trump. Frustrarea față de autorități atinge noi culmi. Donald Trump și Ben Carson sunt acum susținuți de aproape jumătate dintre alegătorii republicani, în mare parte datorită statutului lor de outsideri. Conform sondajului realizat luni de ABC/Post, șase din 10 republicani afirmă că preferă un outsider politic în detrimentul cuiva cu experiență în guvernare. Oamenii sunt de asemenea supărați pe autoritățile de la Washington.
Un sondaj derulat în urmă cu două săptămâni în Iowa de către Des Moines Register/Bloomberg arată că trei din patru republicani din Iowa sunt frustrați de prestația republicanilor din COngres, 54% declarându-se „nemulțumiți” iar 21% „nervoși la culme”. Jeremy Corbyn își face debutul la Prime Minister's Questions Încă de la alegerea sa, debutul domnului Corbyn la PMQs a fost îndelung așteptat Noul lider al Partidului Laburist, Jeremy Corbyn, își va face mai târziu debutul la Prime Minister's Questions, confruntându-se pentru prima dată cu David Cameron.
Dl Corbyn va adresa primele dintre cele șase întrebări la care are dreptul la scurt timp după prânz; prestația sa va fi probabil analizată îndeaproape de mass-media și parlamentarii laburiști. În cadrul aparițiilor săptămânale, el a cerut „mai puțin teatru și mai multe fapte”. A declarat de asemenea că poate renunța la câteva participări și că le cedează colegilor săi. Confruntarea va fi primul test parlamentar al Dl Corbyn în poziție de lider, venind după ce a numit un „cabinet fantomă” și după discursul pe care l-a ținut marți la congresul anual TUC.
Între timp, decizia liderului Partidului laburist de a păstra tăcerea la rostirea imnului național în cadrul unei slujbe ținute marți cu ocazia aniversării a 75 de ani de la Bătălia Angliei a atras critici din partea unor parlamentari conservatori și a ținut prima pagină a ziarelor. Decizia domnului Corbyn de a nu cânta imnul național a atras atenția Un purtător de cuvânt al Dl Corbyn a declarat că acesta „a păstrat tăcerea în mod respectuos” și a recunoscut „eroismul Forțelor aeriene britanice în Bătălia Angliei.”
Însă un membru al cabinetului fantomă al Dl Corbyn, Owen Smith, a declarat pentru emisiunea Two's Newsnight transmisă de BBC că i-ar fi recomandat liderului laburist să cânte imnul național „indiferent” de credința sa că monarhia ar trebui abolită. În jur de doisprezece miniștri din cabinetul fantomă au refuzat să facă parte din echipa de frunte a Dl Corbyn, argumentând prin diferențe de opinie legate de economie, apărare și externe, în timp ce mai puțin de o șesime din partidul parlamentar l-a susținut ca lider. Corespondentul politic al BBC, Robin Brant, declară că diferențele de politică „se cumulează” în Partidul Laburist după numirea domnului Corbyn referitor la poziția sa față de Uniunea Europeană și limita de beneficii.
Dl Corbyn a declarat la conferința TUC că Partidul Laburist va aduce modificări prin care se va elimina integral ideea limitării. Câteva ore mai târziu, Dl Smith, Ministrul Muncii și Pensiilor, a declarat că partidul „este foarte clar” în opoziția exclusivă față de planurile guvernului de a reduce nivelul „cap” de la 26.000 lire la 23.000 lire. Dl Corbyn va fi al cincilea lider laburist cu care se confruntă David Cameron la tribună în ultimul deceniu, de când a preluat conducerea Partidului Conservator. Liderul laburist, care a promis o abordare diferită a politicii, spune că are idei „din surse externe” pentru întrebări pe care să i le adreseze Domnului Cameron și că a primit peste 30.000 de sugestii.
Parlamentarul Islington North a afirmat că PMQs implică un nivel de confruntare prea înalt și că se va abține de la replici și atacuri, angajându-se să se concentreze în schimb pe probleme serioase precum sărăcia, inegalitatea și provocările cu care se confruntă tinerii. Dl Corbyn a declarat că Angela Eagle, Ministrul de finanțe, îi va ține locul la PMQs atunci când el nu poate participa - de exemplu atunci când Dl Cameron se deplasează în străinătate. A exprimat de asemenea ideea că va permite altor colegi să ia cuvântul ocazional, spunând că l-a abordat pe Președintele Camerei Deputaților, John Bercow, pentru a discuta acest aspect.
În 2005, când a preluat conducerea, Dl Cameron a declarat că dorește să renunțe la stilul politic „Punch and Judy” asociat adesea cu PMQs însă a recunoscut câțiva ani mai târziu că nu a reușit în demersul său. De la prima transmisie, în 1990, PMQs a fost considerată un barometru cheie al raționamentului unui lider, al modului în care acesta conduce Camera Deputaților și a poziției sale în rândul colegilor parlamentari, deși criticii afirmă a ca devenit o caricatură și că are nevoie de o reformare profundă. „Cadru în Joburg”: Tineri fără adăpost beneficiază de cursuri de fotografie Este dificil să fii un om fără adăpost în Johannesburg.
Însă un grup de oameni care au trăit pe străzi în copilărie au găsit un mod de a învăța o meserie și de a-și câștiga traiul. „I was shot în Joburg” este un studio non-profit care îi învață pe tinerii fără adăpost să facă fotografii ale zonelor în care trăiesc și să câștige bani din asta. BBC News s-a întâlnit cu unul dintre primii absolvenți ai proiectului. Șeful JD Sports spune că salariile mai mari ar putea dăuna extinderii Președintele JD Sports, Peter Cowgill, declară că o creștere a salariului minim în Marea Britanie ar putea însemna „o putere de cumpărare mai mare în buzunarele potențialilor consumatori.” Este însă puțin probabil ca respectiva putere de cumpărare să depășească costurile mai mari pentru forța de muncă în cadrul firmei, afirmă el.
Costurile ar putea avea impact asupra planurilor de extindere ale JD Sports, a adăugat el, ceea ce ar putea însemna mai puține locuri de muncă noi. Thanasi Kokkinakis susținut de președintele Tennis Australia, Steve Healy Thanasi Kokkinakis ar merita să fie lăudat și nu criticat pentru comportamentul său. Thanasi Kokkinakis a fost victimă colaterală în „furtuna” creată în jurul prietenului său, Nick Kyrgios, iar comportamentul său merită mai degrabă cuvinte de laudă și nu critică, în opinia președintelui Tennis Australia, Steve Healy. | 0 |

mavonic_private_repos/transformers/examples/legacy | mavonic_private_repos/transformers/examples/legacy/question-answering/README.md | #### Fine-tuning BERT on SQuAD1.0 with relative position embeddings
The following examples show how to fine-tune BERT models with different relative position embeddings. The BERT model
`google-bert/bert-base-uncased` was pretrained with default absolute position embeddings. We provide the following pretrained
models which were pre-trained on the same training data (BooksCorpus and English Wikipedia) as in the BERT model
training, but with different relative position embeddings.
* `zhiheng-huang/bert-base-uncased-embedding-relative-key`, trained from scratch with relative embedding proposed by
Shaw et al., [Self-Attention with Relative Position Representations](https://arxiv.org/abs/1803.02155)
* `zhiheng-huang/bert-base-uncased-embedding-relative-key-query`, trained from scratch with relative embedding method 4
in Huang et al. [Improve Transformer Models with Better Relative Position Embeddings](https://arxiv.org/abs/2009.13658)
* `zhiheng-huang/bert-large-uncased-whole-word-masking-embedding-relative-key-query`, fine-tuned from model
`google-bert/bert-large-uncased-whole-word-masking` with 3 additional epochs with relative embedding method 4 in Huang et al.
[Improve Transformer Models with Better Relative Position Embeddings](https://arxiv.org/abs/2009.13658)
##### Base models fine-tuning
```bash
export CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7
torchrun --nproc_per_node=8 ./examples/question-answering/run_squad.py \
--model_name_or_path zhiheng-huang/bert-base-uncased-embedding-relative-key-query \
--dataset_name squad \
--do_train \
--do_eval \
--learning_rate 3e-5 \
--num_train_epochs 2 \
--max_seq_length 512 \
--doc_stride 128 \
--output_dir relative_squad \
--per_device_eval_batch_size=60 \
--per_device_train_batch_size=6
```
Training with the above command leads to the following results. It boosts the BERT default from f1 score of 88.52 to 90.54.
```bash
'exact': 83.6802270577105, 'f1': 90.54772098174814
```
The change of `max_seq_length` from 512 to 384 in the above command leads to the f1 score of 90.34. Replacing the above
model `zhiheng-huang/bert-base-uncased-embedding-relative-key-query` with
`zhiheng-huang/bert-base-uncased-embedding-relative-key` leads to the f1 score of 89.51. The changing of 8 gpus to one
gpu training leads to the f1 score of 90.71.
##### Large models fine-tuning
```bash
export CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7
torchrun --nproc_per_node=8 ./examples/question-answering/run_squad.py \
--model_name_or_path zhiheng-huang/bert-large-uncased-whole-word-masking-embedding-relative-key-query \
--dataset_name squad \
--do_train \
--do_eval \
--learning_rate 3e-5 \
--num_train_epochs 2 \
--max_seq_length 512 \
--doc_stride 128 \
--output_dir relative_squad \
--per_gpu_eval_batch_size=6 \
--per_gpu_train_batch_size=2 \
--gradient_accumulation_steps 3
```
Training with the above command leads to the f1 score of 93.52, which is slightly better than the f1 score of 93.15 for
`google-bert/bert-large-uncased-whole-word-masking`.
#### Distributed training
Here is an example using distributed training on 8 V100 GPUs and Bert Whole Word Masking uncased model to reach a F1 > 93 on SQuAD1.1:
```bash
torchrun --nproc_per_node=8 ./examples/question-answering/run_squad.py \
--model_name_or_path google-bert/bert-large-uncased-whole-word-masking \
--dataset_name squad \
--do_train \
--do_eval \
--learning_rate 3e-5 \
--num_train_epochs 2 \
--max_seq_length 384 \
--doc_stride 128 \
--output_dir ./examples/models/wwm_uncased_finetuned_squad/ \
--per_device_eval_batch_size=3 \
--per_device_train_batch_size=3 \
```
Training with the previously defined hyper-parameters yields the following results:
```bash
f1 = 93.15
exact_match = 86.91
```
This fine-tuned model is available as a checkpoint under the reference
[`google-bert/bert-large-uncased-whole-word-masking-finetuned-squad`](https://huggingface.co/google-bert/bert-large-uncased-whole-word-masking-finetuned-squad).
## Results
Larger batch size may improve the performance while costing more memory.
##### Results for SQuAD1.0 with the previously defined hyper-parameters:
```python
