mavonic_private_repos/transformers/examples/research_projects | mavonic_private_repos/transformers/examples/research_projects/rag-end2end-retriever/README.md | # End-to-End finetuning of RAG (including DPR retriever) for Question Answering.
This finetuning script is actively maintained by [Shamane Siri](https://github.com/shamanez). Feel free to ask questions on the [Forum](https://discuss.huggingface.co/) or post an issue on [GitHub](https://github.com/huggingface/transformers/issues/new/choose) and tag @shamanez.
Others that helped out: Patrick von Platen (@patrickvonplaten), Quentin Lhoest (@lhoestq), and Rivindu Weerasekera (@rivinduw)
The original RAG implementation is able to train the question encoder and generator end-to-end.
This extension enables complete end-to-end training of RAG including the context encoder in the retriever component.
Please read the [accompanying blog post](https://shamanesiri.medium.com/how-to-finetune-the-entire-rag-architecture-including-dpr-retriever-4b4385322552) for details on this implementation.
The original RAG code has also been modified to work with the latest versions of pytorch lightning (version 1.2.10) and RAY (version 1.3.0). All other implementation details remain the same as the [original RAG code](https://github.com/huggingface/transformers/tree/main/examples/research_projects/rag).
Read more about RAG at https://arxiv.org/abs/2005.11401.
This code can be modified to experiment with other research on retrival augmented models which include training of the retriever (e.g. [REALM](https://arxiv.org/abs/2002.08909) and [MARGE](https://arxiv.org/abs/2006.15020)).
To start training, use the bash script (finetune_rag_ray_end2end.sh) in this folder. This script also includes descriptions on each command-line argument used.
# Latest Update
⚠️ Updated the rag-end2end-retriever to be compatible with PL==1.6.4 and RAY==1.13.0 (latest versions to the date 2022-June-11)
# Note
⚠️ This project should be run with pytorch-lightning==1.3.1 which has a potential security vulnerability
# Testing
The following two bash scripts can be used to quickly test the implementation.
1. sh ./test_run/test_finetune.sh script
- Tests the full end-to-end fine-tuning ability with a dummy knowlendge-base and dummy training dataset (check test_dir directory).
- Users can replace the dummy dataset and knowledge-base with their own to do their own finetuning.
- Please read the comments in the test_finetune.sh file.
2. sh ./test_run/test_rag_new_features.sh
- Tests the newly added functions (set_context_encoder and set_context_encoder_tokenizer) related to modeling rag.
- This is sufficient to check the model's ability to use the set functions correctly.
# Comparison of end2end RAG (including DPR finetuning) VS original-RAG
We conducted a simple experiment to investigate the effectiveness of this end2end training extension using the SQuAD dataset. Please execute the following steps to reproduce the results.
- Create a knowledge-base using all the context passages in the SQuAD dataset with their respective titles.
- Use the question-answer pairs as training data.
- Train the system for 10 epochs.
- Test the Exact Match (EM) score with the SQuAD dataset's validation set.
- Training dataset, the knowledge-base, and hyperparameters used in experiments can be accessed from [here](https://drive.google.com/drive/folders/1qyzV-PaEARWvaU_jjpnU_NUS3U_dSjtG?usp=sharing).
# Results
- We train both models for 10 epochs.
| Model Type | EM-Score|
| --------------------| --------|
| RAG-original | 28.12 |
| RAG-end2end with DPR| 40.02 |

Knowledge of Aaron, along with his brother Moses, comes exclusively from religious texts, such as the Bible and Quran. The Hebrew Bible relates that, unlike Moses, who grew up in the Egyptian royal court, Aaron and his elder sister Miriam remained with their kinsmen in the eastern border-land of Egypt (Goshen). When Moses first confronted the Egyptian king about the Israelites, Aaron served as his brother's spokesman ("prophet") to the Pharaoh. Part of the Law (Torah) that Moses received from God at Sinai granted Aaron the priesthood for himself and his male descendants, and he became the first High Priest of the Israelites. Aaron died before the Israelites crossed the North Jordan river and he was buried on Mount Hor (Numbers 33:39; Deuteronomy 10:6 says he died and was buried at Moserah). Aaron is also mentioned in the New Testament of the Bible. According to the Book of Exodus, Aaron first functioned as Moses' assistant. Because Moses complained that he could not speak well, God appointed Aaron as Moses' "prophet" (Exodus 4:10-17; 7:1). At the command of Moses, he let his rod turn into a snake. Then he stretched out his rod in order to bring on the first three plagues. After that, Moses tended to act and speak for himself. During the journey in the wilderness, Aaron was not always prominent or active. At the battle with Amalek, he was chosen with Hur to support the hand of Moses that held the "rod of God". When the revelation was given to Moses at biblical Mount Sinai, he headed the elders of Israel who accompanied Moses on the way to the summit.
"Pokémon" Pokémon , also known as in Japan, is a media franchise managed by The Pokémon Company, a Japanese consortium between Nintendo, Game Freak, and Creatures. The franchise copyright is shared by all three companies, but Nintendo is the sole owner of the trademark. The franchise was created by Satoshi Tajiri in 1995, and is centered on fictional creatures called "Pokémon", which humans, known as Pokémon Trainers, catch and train to battle each other for sport. The English slogan for the franchise is "Gotta Catch 'Em All". Works within the franchise are set in the Pokémon universe. The franchise began as "Pokémon Red" and "Green" (released outside of Japan as "Pokémon Red" and "Blue"), a pair of video games for the original Game Boy that were developed by Game Freak and published by Nintendo in February 1996. "Pokémon" has since gone on to become the highest-grossing media franchise of all time, with over in revenue up until March 2017. The original video game series is the second best-selling video game franchise (behind Nintendo's "Mario" franchise) with more than 300million copies sold and over 800million mobile downloads. In addition, the "Pokémon" franchise includes the world's top-selling toy brand, the top-selling trading card game with over 25.7billion cards sold, an anime television series that has become the most successful video game adaptation with over 20 seasons and 1,000 episodes in 124 countries, as well as an anime film series, a , books, manga comics, music, and merchandise. The franchise is also represented in other Nintendo media, such as the "Super Smash Bros." series. In November 2005, 4Kids Entertainment, which had managed the non-game related licensing of "Pokémon", announced that it had agreed not to renew the "Pokémon" representation agreement. The Pokémon Company International oversees all "Pokémon" licensing outside Asia. | 0 |

"""
Implementation of a new method for fine-tuning transformer models that we call
Information Gain Filtration 'IGF' on WikiText data set and compared the results
with the standard fine-tuning method
Steps followed in the code:
1) Generate a objective dataset of pairs (X, IG(X)). IG(X)--Informativeness of context 'X'.
Our IG (information gain) model is learning to predict the ‘informativeness’ of a particular
context. Informativeness is the change in metric between the model’s accuracy on an
objective set before and after seeing that context. For casual language modeling, the
metric is perplexity.
2) A secondary learner is trained to infer a function approximation for IG using the dataset
created in (1).
3) The learner created in (2) is used to inform the fine-tuning process and filter out low informative samples.
Last, a plot is generated to compare the performance of IGF to standard fine-tuning without any filtering

# Information Gain Filtration(IGF)
Authors @Tuko @mraunak
This folder contains the code how to implement IGF for finetuning on GPT-2.
## What is IGF?
Here we present a general fine-tuning method that we call information gain filtration for improving the overall training efficiency and final
performance of language model fine-tuning(see paper below). The method is an alternative fine-tuning method that trains
a secondary model (e.g., a simple convolutional network) to predict the amount of information
gained over a given pre-trained model. The secondary model is lightweight and trained to
predict the Information Gain measure. Information Gain is defined as the change in a loss
function for a model before and after an SGD update with a sample (Equation X in the paper).
A small subset of the training set named the “objective” set, is used to measure information
gain on the pre-trained model, and consequently to train the secondary model. After
training, the model is used for filtering samples for the fine-tuning process. Therefore,
a high information gain value would suggest a sample is informative, whereas a low value
would suggest a non-informative sample that should be filtered out. Thus, a thresholding
strategy is defined to select informative samples. With such a strategy, samples are filtered
and once enough samples are selected to form a mini-batch and a usual fine-tuning/optimization
step is applied. The filtration process is repeated until the fine-tuning process is over.
Paper [Selecting Informative Contexts Improves Language Model Finetuning](https://arxiv.org/abs/2005.00175)
# Results
Several experiments were conducted to show the robustness of the IGF method versus the
standard fine-tuning process. For example, we achieve a median perplexity of 54.0 on the
Books dataset compared to 57.3 for standard fine-tuning on GPT-2 Small. The code was
implemented using the Transformers library and Pytorch. While the method may seem more
expensive, we saw enough evidence that it may lead to a performance benefit in the final models.
Figure 1: Comparing IGF to Standard Fine-tuning:
IGF with constant (p < 10−3 , t-test) and shifting(p < 10−6 , t-test) thresholding significantly outperform standard fine-tuning. The left-hand figure shows
test-set perplexity after each fine-tuning batch, averaged over 50 runs (error bars denote ± one standard error). The right-hand figure shows the perplexity of each
method after 60 batches. IGF with shifting thresholding (red) clearly improves over standard batched fine-tuning with Adam
## How to use this project?
To fine-tune a transformer model with IGF on a language modeling task, use the following script:
- `model_name_or_path`: Path to pretrained model or model identifier from huggingface.co/models
- `data_file`: A jbl file containing tokenized data which can be split as objective dataset,
train_dataset and test_dataset
- `igf_data_file`: A jbl file containing the context and information gain pairs to train secondary learner.
- `context_len`: The maximum total input sequence length after tokenization. Sequences longer
than this will be truncated, sequences shorter will be padded.
- `size_objective_set`: Number of articles that are long enough to be used as our objective set"
- `min_len`: The minimum length of the article to be used as objective set
- `trim`: Truncate the example if it exceeds context length
- `eval_freq`: Secondary model evaluation can be triggered at eval_freq
- `max_steps`: To calculate training epochs
- `number`: The number of examples split to be used as objective_set/test_data
- `secondary_learner_batch_size`: The batch size of training data for secondary learner
- `secondary_learner_max_epochs`: The number of epochs to train secondary learner
- `recopy_model`: Reset the model to the original pretrained GPT-2 weights after each iteration
- `eval_interval`: Decay the selectivity of our secondary learner filter from"
1 standard deviation above average to 1 below average after eval_interval(10) batches"

Author: @VictorSanh
This folder contains the original code used to train Distil* as well as examples showcasing how to use DistilBERT, DistilRoBERTa and DistilGPT2.
**January 20, 2020 - Bug fixing** We have recently discovered and fixed [a bug](https://github.com/huggingface/transformers/commit/48cbf267c988b56c71a2380f748a3e6092ccaed3) in the evaluation of our `run_*.py` scripts that caused the reported metrics to be over-estimated on average. We have updated all the metrics with the latest runs.
**December 6, 2019 - Update** We release **DistilmBERT**: 92% of `bert-base-multilingual-cased` on XNLI. The model supports 104 different languages listed [here](https://github.com/google-research/bert/blob/master/multilingual.md#list-of-languages).
**November 19, 2019 - Update** We release German **DistilBERT**: 98.8% of `bert-base-german-dbmdz-cased` on NER tasks.
**October 23, 2019 - Update** We release **DistilRoBERTa**: 95% of `RoBERTa-base`'s performance on GLUE, twice as fast as RoBERTa while being 35% smaller.
**October 3, 2019 - Update** We release our [NeurIPS workshop paper](https://arxiv.org/abs/1910.01108) explaining our approach on **DistilBERT**. It includes updated results and further experiments. We applied the same method to GPT2 and release the weights of **DistilGPT2**. DistilGPT2 is two times faster and 33% smaller than GPT2. **The paper supersedes our [previous blogpost](https://medium.com/huggingface/distilbert-8cf3380435b5) with a different distillation loss and better performances. Please use the paper as a reference when comparing/reporting results on DistilBERT.**
**September 19, 2019 - Update:** We fixed bugs in the code and released an updated version of the weights trained with a modification of the distillation loss. DistilBERT now reaches 99% of `BERT-base`'s performance on GLUE, and 86.9 F1 score on SQuAD v1.1 dev set (compared to 88.5 for `BERT-base`). We will publish a formal write-up of our approach in the near future!
## What is Distil*
Distil* is a class of compressed models that started with DistilBERT. DistilBERT stands for Distilled-BERT. DistilBERT is a small, fast, cheap and light Transformer model based on Bert architecture. It has 40% less parameters than `bert-base-uncased`, runs 60% faster while preserving 97% of BERT's performances as measured on the GLUE language understanding benchmark. DistilBERT is trained using knowledge distillation, a technique to compress a large model called the teacher into a smaller model called the student. By distillating Bert, we obtain a smaller Transformer model that bears a lot of similarities with the original BERT model while being lighter, smaller and faster to run. DistilBERT is thus an interesting option to put large-scaled trained Transformer model into production.
We have applied the same method to other Transformer architectures and released the weights:
- GPT2: on the [WikiText-103](https://blog.einstein.ai/the-wikitext-long-term-dependency-language-modeling-dataset/) benchmark, GPT2 reaches a perplexity on the test set of 16.3 compared to 21.1 for **DistilGPT2** (after fine-tuning on the train set).
- RoBERTa: **DistilRoBERTa** reaches 95% of `RoBERTa-base`'s performance on GLUE while being twice faster and 35% smaller.
- German BERT: **German DistilBERT** reaches 99% of `bert-base-german-dbmdz-cased`'s performance on German NER (CoNLL-2003).
- Multilingual BERT: **DistilmBERT** reaches 92% of Multilingual BERT's performance on XNLI while being twice faster and 25% smaller. The model supports 104 languages listed [here](https://github.com/google-research/bert/blob/master/multilingual.md#list-of-languages).
For more information on DistilBERT, please refer to our [NeurIPS workshop paper](https://arxiv.org/abs/1910.01108).
Here are the results on the dev sets of GLUE:

Here are the results on the *test* sets for 6 of the languages available in XNLI. The results are computed in the zero shot setting (trained on the English portion and evaluated on the target language portion):
| Model | English | Spanish | Chinese | German | Arabic | Urdu |
| :---: | :---: | :---: | :---: | :---: | :---: | :---:|
| mBERT base cased (computed) | 82.1 | 74.6 | 69.1 | 72.3 | 66.4 | 58.5 |
| mBERT base uncased (reported)| 81.4 | 74.3 | 63.8 | 70.5 | 62.1 | 58.3 |
| DistilmBERT | 78.2 | 69.1 | 64.0 | 66.3 | 59.1 | 54.7 |
## Setup
This part of the library has only be tested with Python3.6+. There are few specific dependencies to install before launching a distillation, you can install them with the command `pip install -r requirements.txt`.
**Important note:** The training scripts have been updated to support PyTorch v1.2.0 (there are breaking changes compared to v1.1.0).
## How to use DistilBERT
Transformers includes five pre-trained Distil* models, currently only provided for English and German (we are investigating the possibility to train and release a multilingual version of DistilBERT):
- `distilbert-base-uncased`: DistilBERT English language model pretrained on the same data used to pretrain Bert (concatenation of the Toronto Book Corpus and full English Wikipedia) using distillation with the supervision of the `bert-base-uncased` version of Bert. The model has 6 layers, 768 dimension and 12 heads, totalizing 66M parameters.
- `distilbert-base-uncased-distilled-squad`: A finetuned version of `distilbert-base-uncased` finetuned using (a second step of) knowledge distillation on SQuAD 1.0. This model reaches a F1 score of 86.9 on the dev set (for comparison, Bert `bert-base-uncased` version reaches a 88.5 F1 score).
- `distilbert-base-cased`: DistilBERT English language model pretrained on the same data used to pretrain Bert (concatenation of the Toronto Book Corpus and full English Wikipedia) using distillation with the supervision of the `bert-base-cased` version of Bert. The model has 6 layers, 768 dimension and 12 heads, totalizing 65M parameters.
- `distilbert-base-cased-distilled-squad`: A finetuned version of `distilbert-base-cased` finetuned using (a second step of) knowledge distillation on SQuAD 1.0. This model reaches a F1 score of 87.1 on the dev set (for comparison, Bert `bert-base-cased` version reaches a 88.7 F1 score).
- `distilbert-base-german-cased`: DistilBERT German language model pretrained on 1/2 of the data used to pretrain Bert using distillation with the supervision of the `bert-base-german-dbmdz-cased` version of German DBMDZ Bert. For NER tasks the model reaches a F1 score of 83.49 on the CoNLL-2003 test set (for comparison, `bert-base-german-dbmdz-cased` reaches a 84.52 F1 score), and a F1 score of 85.23 on the GermEval 2014 test set (`bert-base-german-dbmdz-cased` reaches a 86.89 F1 score).
- `distilgpt2`: DistilGPT2 English language model pretrained with the supervision of `gpt2` (the smallest version of GPT2) on [OpenWebTextCorpus](https://skylion007.github.io/OpenWebTextCorpus/), a reproduction of OpenAI's WebText dataset. The model has 6 layers, 768 dimension and 12 heads, totalizing 82M parameters (compared to 124M parameters for GPT2). On average, DistilGPT2 is two times faster than GPT2.
- `distilroberta-base`: DistilRoBERTa English language model pretrained with the supervision of `roberta-base` solely on [OpenWebTextCorpus](https://skylion007.github.io/OpenWebTextCorpus/), a reproduction of OpenAI's WebText dataset (it is ~4 times less training data than the teacher RoBERTa). The model has 6 layers, 768 dimension and 12 heads, totalizing 82M parameters (compared to 125M parameters for RoBERTa-base). On average DistilRoBERTa is twice as fast as Roberta-base.
- `distilbert-base-multilingual-cased`: DistilmBERT multilingual model pretrained with the supervision of `bert-base-multilingual-cased` on the concatenation of Wikipedia in 104 different languages. The model supports the 104 languages listed [here](https://github.com/google-research/bert/blob/master/multilingual.md#list-of-languages). The model has 6 layers, 768 dimension and 12 heads, totalizing 134M parameters (compared to 177M parameters for mBERT-base). On average DistilmBERT is twice as fast as mBERT-base.
Using DistilBERT is very similar to using BERT. DistilBERT share the same tokenizer as BERT's `bert-base-uncased` even though we provide a link to this tokenizer under the `DistilBertTokenizer` name to have a consistent naming between the library models.
```python
tokenizer = DistilBertTokenizer.from_pretrained('distilbert-base-cased')
model = DistilBertModel.from_pretrained('distilbert-base-cased')
input_ids = torch.tensor(tokenizer.encode("Hello, my dog is cute")).unsqueeze(0)
outputs = model(input_ids)
last_hidden_states = outputs[0] # The last hidden-state is the first element of the output tuple
```
Similarly, using the other Distil* models simply consists in calling the base classes with a different pretrained checkpoint:
- DistilBERT uncased: `model = DistilBertModel.from_pretrained('distilbert-base-uncased')`
- DistilGPT2: `model = GPT2Model.from_pretrained('distilgpt2')`
- DistilRoBERTa: `model = RobertaModel.from_pretrained('distilroberta-base')`
- DistilmBERT: `model = DistilBertModel.from_pretrained('distilbert-base-multilingual-cased')`
## How to train Distil*
In the following, we will explain how you can train DistilBERT.
### A. Preparing the data
The weights we release are trained using a concatenation of Toronto Book Corpus and English Wikipedia (same training data as the English version of BERT).
To avoid processing the data several time, we do it once and for all before the training. From now on, will suppose that you have a text file `dump.txt` which contains one sequence per line (a sequence being composed of one of several coherent sentences).
First, we will binarize the data, i.e. tokenize the data and convert each token in an index in our model's vocabulary.
```bash
python scripts/binarized_data.py \
--file_path data/dump.txt \
--tokenizer_type bert \
--tokenizer_name bert-base-uncased \
--dump_file data/binarized_text
```
Our implementation of masked language modeling loss follows [XLM](https://github.com/facebookresearch/XLM)'s one and smooths the probability of masking with a factor that put more emphasis on rare words. Thus we count the occurrences of each tokens in the data:
```bash
python scripts/token_counts.py \
--data_file data/binarized_text.bert-base-uncased.pickle \
--token_counts_dump data/token_counts.bert-base-uncased.pickle \
--vocab_size 30522
```
### B. Training
Training with distillation is really simple once you have pre-processed the data:
```bash
python train.py \
--student_type distilbert \
--student_config training_configs/distilbert-base-uncased.json \
--teacher_type bert \
--teacher_name bert-base-uncased \
--alpha_ce 5.0 --alpha_mlm 2.0 --alpha_cos 1.0 --alpha_clm 0.0 --mlm \
--freeze_pos_embs \
--dump_path serialization_dir/my_first_training \
--data_file data/binarized_text.bert-base-uncased.pickle \
--token_counts data/token_counts.bert-base-uncased.pickle \
--force # overwrites the `dump_path` if it already exists.
```
By default, this will launch a training on a single GPU (even if more are available on the cluster). Other parameters are available in the command line, please look in `train.py` or run `python train.py --help` to list them.
We highly encourage you to use distributed training for training DistilBERT as the training corpus is quite large. Here's an example that runs a distributed training on a single node having 4 GPUs:
```bash
export NODE_RANK=0
export N_NODES=1
export N_GPU_NODE=4

**Tips:** Starting distilled training with good initialization of the model weights is crucial to reach decent performance. In our experiments, we initialized our model from a few layers of the teacher (Bert) itself! Please refer to `scripts/extract.py` and `scripts/extract_distilbert.py` to create a valid initialization checkpoint and use `--student_pretrained_weights` argument to use this initialization for the distilled training!
Happy distillation!

Author: @joeddav
This script provides a way to improve the speed and memory performance of a zero-shot classifier by training a more
efficient student model from the zero-shot teacher's predictions over an unlabeled dataset.
The zero-shot classification pipeline uses a model pre-trained on natural language inference (NLI) to determine the
compatibility of a set of candidate class names with a given sequence. This serves as a convenient out-of-the-box
classifier without the need for labeled training data. However, for a given sequence, the method requires each
possible label to be fed through the large NLI model separately. Thus for `N` sequences and `K` classes, a total of
`N*K` forward passes through the model are required. This requirement slows inference considerably, particularly as
`K` grows.
Given (1) an unlabeled corpus and (2) a set of candidate class names, the provided script trains a student model
with a standard classification head with `K` output dimensions. The resulting student model can then be used for
classifying novel text instances with a significant boost in speed and memory performance while retaining similar
classification performance to the original zero-shot model
### Usage
A teacher NLI model can be distilled to a more efficient student model by running [`distill_classifier.py`](https://github.com/huggingface/transformers/blob/main/examples/research_projects/zero-shot-distillation/distill_classifier.py):
```bash
python distill_classifier.py \
--data_file <unlabeled_data.txt> \
--class_names_file <class_names.txt> \
--output_dir <output_dir>
```
`<unlabeled_data.txt>` should be a text file with a single unlabeled example per line. `<class_names.txt>` is a text file with one class name per line.
Other optional arguments include:
- `--teacher_name_or_path` (default: `roberta-large-mnli`): The name or path of the NLI teacher model.
- `--student_name_or_path` (default: `distillbert-base-uncased`): The name or path of the student model which will
be fine-tuned to copy the teacher predictions.
- `--hypothesis_template` (default `"This example is {}."`): The template used to turn each label into an NLI-style
hypothesis when generating teacher predictions. This template must include a `{}` or similar syntax for the
candidate label to be inserted into the template. For example, the default template is `"This example is {}."` With
the candidate label `sports`, this would be fed into the model like `[CLS] sequence to classify [SEP] This example
is sports . [SEP]`.
- `--multi_class`: Whether or not multiple candidate labels can be true. By default, the scores are normalized such
that the sum of the label likelihoods for each sequence is 1. If `--multi_class` is passed, the labels are
considered independent and probabilities are normalized for each candidate by doing a softmax of the entailment
score vs. the contradiction score. This is sometimes called "multi-class multi-label" classification.
- `--temperature` (default: `1.0`): The temperature applied to the softmax of the teacher model predictions. A
higher temperature results in a student with smoother (lower confidence) predictions than the teacher while a value
`<1` resultings in a higher-confidence, peaked distribution. The default `1.0` is equivalent to no smoothing.
- `--teacher_batch_size` (default: `32`): The batch size used for generating a single set of teacher predictions.
Does not affect training. Use `--per_device_train_batch_size` to change the training batch size.
Any of the arguments in the 🤗 Trainer's
[`TrainingArguments`](https://huggingface.co/transformers/main_classes/trainer.html?#trainingarguments) can also be
modified, such as `--learning_rate`, `--fp16`, `--no_cuda`, `--warmup_steps`, etc. Run `python distill_classifier.py
-h` for a full list of available arguments or consult the [Trainer
documentation](https://huggingface.co/transformers/main_classes/trainer.html#trainingarguments).
> **Note**: Distributed and TPU training are not currently supported. Single-node multi-GPU is supported, however,
and will run automatically if multiple GPUs are available.
### Example: Topic classification
> A full colab demo notebook of this example can be found [here](https://colab.research.google.com/drive/1mjBjd0cR8G57ZpsnFCS3ngGyo5nCa9ya?usp=sharing).
Let's say we're interested in classifying news articles into one of four topic categories: "the world", "sports",
"business", or "science/tech". We have an unlabeled dataset, [AG's News](https://huggingface.co/datasets/ag_news),
which corresponds to this problem (in reality AG's News is annotated, but we will pretend it is not for the sake of
example).
We can use an NLI model like `roberta-large-mnli` for zero-shot classification like so:
```python
>>> class_names = ["the world", "sports", "business", "science/tech"]
>>> hypothesis_template = "This text is about {}."
>>> sequence = "A new moon has been discovered in Jupiter's orbit"
>>> zero_shot_classifier = pipeline("zero-shot-classification", model="roberta-large-mnli")
>>> zero_shot_classifier(sequence, class_names, hypothesis_template=hypothesis_template)
{'sequence': "A new moon has been discovered in Jupiter's orbit",
'labels': ['science/tech', 'the world', 'business', 'sports'],
'scores': [0.7035840153694153, 0.18744826316833496, 0.06027870625257492, 0.04868902638554573]}
```
Unfortunately, inference is slow since each of our 4 class names must be fed through the large model for every
sequence to be classified. But with our unlabeled data we can distill the model to a small distilbert classifier to
make future inference much faster.
To run the script, we will need to put each training example (text only) from AG's News on its own line in
`agnews/train_unlabeled.txt`, and each of the four class names in the newline-separated `agnews/class_names.txt`.
Then we can run distillation with the following command:
```bash
python distill_classifier.py \
--data_file ./agnews/unlabeled.txt \
--class_names_files ./agnews/class_names.txt \
--teacher_name_or_path roberta-large-mnli \
--hypothesis_template "This text is about {}." \
--output_dir ./agnews/distilled
```
The script will generate a set of soft zero-shot predictions from `roberta-large-mnli` for each example in
`agnews/unlabeled.txt`. It will then train a student distilbert classifier on the teacher predictions and
save the resulting model in `./agnews/distilled`.
The resulting model can then be loaded and used like any other pre-trained classifier:
```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer
model = AutoModelForSequenceClassification.from_pretrained("./agnews/distilled")
tokenizer = AutoTokenizer.from_pretrained("./agnews/distilled")
```
and even used trivially with a `TextClassificationPipeline`:
```python
>>> distilled_classifier = TextClassificationPipeline(model=model, tokenizer=tokenizer, return_all_scores=True)
>>> distilled_classifier(sequence)
[[{'label': 'the world', 'score': 0.14899294078350067},
{'label': 'sports', 'score': 0.03205857425928116},
{'label': 'business', 'score': 0.05943061783909798},
{'label': 'science/tech', 'score': 0.7595179080963135}]]
```
> Tip: pass `device=0` when constructing a pipeline to run on a GPU
As we can see, the results of the student closely resemble that of the trainer despite never having seen this
example during training. Now let's do a quick & dirty speed comparison simulating 16K examples with a batch size of
16:
```python
for _ in range(1000):
zero_shot_classifier([sequence] * 16, class_names)
# runs in 1m 23s on a single V100 GPU
```
```python
%%time
for _ in range(1000):
distilled_classifier([sequence] * 16)
# runs in 10.3s on a single V100 GPU
```
As we can see, the distilled student model runs an order of magnitude faster than its teacher NLI model. This is
also a seeting where we only have `K=4` possible labels. The higher the number of classes for a given task, the more
drastic the speedup will be, since the zero-shot teacher's complexity scales linearly with the number of classes.
Since we secretly have access to ground truth labels for AG's news, we can evaluate the accuracy of each model. The
original zero-shot model `roberta-large-mnli` gets an accuracy of 69.3% on the held-out test set. After training a
student on the unlabeled training set, the distilled model gets a similar score of 70.4%.
Lastly, you can share the distilled model with the community and/or use it with our inference API by [uploading it
to the 🤗 Hub](https://huggingface.co/transformers/model_sharing.html). We've uploaded the distilled model from this
example at
[joeddav/distilbert-base-uncased-agnews-student](https://huggingface.co/joeddav/distilbert-base-uncased-agnews-student).

maximum acceptable input length for the model if that argument is not provided.
* :obj:`False` or :obj:`'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of
different lengths).
max_length (:obj:`int`, `optional`):
Maximum length of the ``input_values`` of the returned list and optionally padding length (see above).
max_length_labels (:obj:`int`, `optional`):
Maximum length of the ``labels`` returned list and optionally padding length (see above).
pad_to_multiple_of (:obj:`int`, `optional`):
If set will pad the sequence to a multiple of the provided value.
This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability >=
7.5 (Volta).

Welcome to the robust speech recognition challenge 🎙️ !
The goal of this event is to build **robust**, **real-world** speech recognition (ASR) systems in as many languages as possible 🌏🌍🌎.
If necessary and available, free access to a V100S 32 GB GPU will kindly be provided by the [OVHcloud team](https://www.ovhcloud.com/) 🚀.
This document summarizes all the relevant information required for the speech community event 📋.
To sign-up, please see [this forum post](https://discuss.huggingface.co/t/open-to-the-community-robust-speech-recognition-challenge/13614) 🤗. Please make sure to:
- Read it in detail
- Fill the google form

## TLDR
Participants are encouraged to leverage pre-trained speech recognition checkpoints,
preferably [facebook/wav2vec2-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53),
to train a speech recognition system in a language of their choice.
Speech recognition systems should be trained using **PyTorch**, **🤗 Transformers**, and, **🤗 Datasets**.
For more information on how to install the above libraries, please read through
[How to install pytorch, transformers, datasets](#how-to-install-relevant-libraries).
Participants can make use of whatever data they think is useful to build a
speech recognition system for **real-world** audio data -
**except** the Common Voice `"test"` split of their chosen language.
The section [Data and preprocessing](#data-and-preprocessing) explains
in more detail what audio data can be used, how to find suitable audio data, and
how the audio data can be processed.
For training, it is recommended to use the [official training script](https://github.com/huggingface/transformers/blob/main/examples/pytorch/speech-recognition/run_speech_recognition_ctc.py) or a modification thereof. A step-by-step guide on how to fine-tune
an acoustic model for a speech recognition system can be found under [How to fine-tune an acoustic model](#how-to-finetune-an-acoustic-model).
If possible it is encouraged to fine-tune the acoustic models on local GPU machines, but
if those are not available, the OVH could team kindly provides a limited
number of GPUs for the event. Simply fill out [this google form](https://forms.gle/GFZkMkKLiufi75g28) to get access to a GPU.
For more information on how to train an acoustic model on one of OVH's GPU - see [How to fine-tune a speech recognition model with OVHcould](#how-to-fine-tune-with-ovh-cloud).
The performance of speech recognition system can often significantly be improved by adding a
language model for decoding. For more information on how to add a language model, please
take a look at [How to combine n-gram language models with speech recognition models](#how-to-combine-n-gram-with-model).
During the event, the speech recognition system will be evaluated on both the Common Voice `"test"` split
of the participants' chosen language as well as the *real-world* `"dev"` data provided by
the Hugging Face team.
At the end of the robust speech recognition challenge, the speech recognition system will also be evaluated on the
*real-world* `"test"` data provided by the Hugging Face team. Each participant should add an
`eval.py` script to her/his model repository in a specific format that lets one easily
evaluate the speech recognition system on both Common Voice's `"test"` data as well as the *real-world* audio
data. Please read through the [Evaluation](#evaluation) section to make sure your evaluation script is in the correct format. Speech recognition systems
with evaluation scripts in an incorrect format can sadly not be considered for the Challenge.
At the end of the event, the best performing speech recognition system
will receive a prize 🏆 - more information regarding the prizes can be found under [Prizes](#prizes).
We believe that framing the event as a competition is more fun, but at the core, the event is about
creating speech recognition systems in as many languages as possible as a community.
This can be achieved by working together, helping each other to solve bugs, share important findings, etc...🤗
**Note**:
Please, read through the section on [Communication & Problems](#communication-and-problems) to make sure you
know how to ask for help, etc...
All important announcements will be made on discord. Please make sure that
you've joined [this discord channel](https://discord.gg/SHr5wC7m)
Also, please make sure that you have been added to the [Speech Event Organization](https://huggingface.co/speech-recognition-community-v2).
You should have received an invite by email. If you didn't receive an invite, please contact the organizers, *e.g.* Anton, Patrick, or Omar directly on discord.
## Important dates
## Data and preprocessing
In this section, we will quickly go over how to find suitable training data and
how to preprocess it.
To begin with, **all data except Common Voice's `"test"` data can be used as training data.**
The exception includes all Common Voice versions as the test data split of later Common Voice versions often
overlaps with the one of previous versions, *e.g.* the test data of Common Voice 7 in English is
to a big part identical to the test data of Common Voice 6 in English:
```python
load_dataset("mozilla-foundation/common_voice_7_0", "en", split="test")
```
includes more or less the same data as
```python
load_dataset("mozilla-foundation/common_voice_6_1", "en", split="test")
```
However, we strongly encourage participants to make use of Common Voice's other splits, *e.g.* `"train"` and `"validation"`.
For most languages, the Common Voice dataset offers already a decent amount of training data. It is usually
always advantageous to collect additional data. To do so, the participants are in a first step encouraged to search the
Hugging Face Hub for additional audio data, for example by selecting the category
["speech-processing"](https://huggingface.co/datasets?task_categories=task_categories:speech-processing&sort=downloads).
All datasets that are available on the Hub can be downloaded via the 🤗 Datasets library in the same way Common Voice is downloaded.
If one wants to combine multiple datasets for training, it might make sense to take a look at
the [`interleave_datasets`](https://huggingface.co/docs/datasets/package_reference/main_classes?highlight=interleave#datasets.interleave_datasets) function.
In addition, participants can also make use of their audio data. Here, please make sure that you **are allowed to use the audio data**. E.g., if audio data
is taken from media platforms, such as YouTube, it should be verified that the media platform and the owner of the data have given her/his approval to use the audio
data in the context of machine learning research. If you are not sure whether the data you want to use has the appropriate licensing, please contact the Hugging Face
team on discord.
Next, let's talk about preprocessing. Audio data and transcriptions have to be brought into the correct format when
training the acoustic model (example shown in [How to fine-tune an acoustic model](#how-to-finetune-an-acoustic-model)).
It is recommended that this is done by using 🤗 Datasets `.map()` function as shown
[here](https://github.com/huggingface/transformers/blob/9a2dabae7002258e41419491c73dd43ad61b5de7/examples/pytorch/speech-recognition/run_speech_recognition_ctc.py#L444). As can be
see we can pass some characters that will be removed from the transcriptions, *e.g.*: `--chars_to_ignore , ? . ! - \; \: \" “ % ‘ ” � \`
on the official ["Single GPU Example"](https://github.com/huggingface/transformers/tree/main/examples/pytorch/speech-recognition#single-gpu-ctc).
The participants are free to modify this preprocessing by removing more characters or even replacing characters as
it is done in the [official blog post](https://github.com/huggingface/transformers/blob/9a2dabae7002258e41419491c73dd43ad61b5de7/examples/pytorch/speech-recognition/run_speech_recognition_ctc.py#L444).
**However**, there are some rules regarding what characters are allowed to be removed/replaced and which are not.
These rules are not this straightforward and therefore often have to be evaluated case-by-case.
It is allowed (and recommended) to normalize the data to only have lower-case characters. It is also allowed (and recommended) to remove typographical
symbols and punctuation marks. A list of such symbols can *e.g.* be found [here](https://en.wikipedia.org/wiki/List_of_typographical_symbols_and_punctuation_marks) - however here we already must be careful. We should **not** remove a symbol that would change the meaning of the words, *e.g.* in English,
we should not remove the single quotation mark `'` since it would change the meaning of the word `"it's"` to `"its"` which would then be incorrect.
So the golden rule here is to not remove any characters that could change the meaning of a word into another word. This is not always obvious and should
be given some consideration. As another example, it is fine to remove the "Hyphen-minus" sign "`-`" since it doesn't change the
meaning of a word to another one. *E.g.* "`fine-tuning`" would be changed to "`finetuning`" which has still the same meaning.
Since those choices are not always obvious when in doubt feel free to ask on Discord or even better post your question on the forum, as was
done, *e.g.* [here](https://discuss.huggingface.co/t/spanish-asr-fine-tuning-wav2vec2/4586).
## How to install relevant libraries
The following libraries are required to fine-tune a speech model with 🤗 Transformers and 🤗 Datasets in PyTorch.
- [PyTorch](https://pytorch.org/)
- [Transformers](https://github.com/huggingface/transformers)
- [Datasets](https://github.com/huggingface/datasets)
We recommend installing 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
```
To begin with please make sure you have PyTorch and CUDA correctly installed.
The following command should return ``True``:
```bash
python -c "import torch; print(torch.cuda.is_available())"
```
If the above command doesn't print ``True``, in the first step, please follow the
instructions [here](https://pytorch.org/) to install PyTorch with CUDA.
We strongly recommend making use of the provided PyTorch examples scripts in [transformers/examples/pytorch/speech-recognition](https://github.com/huggingface/transformers/tree/main/examples/pytorch/speech-recognition) to train your speech recognition
system.
In all likelihood, you will adjust one of the example scripts, so we recommend forking and cloning the 🤗 Transformers repository as follows.
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 PyTorch environment by running the following command your virtual environment:
```bash
$ pip install -e ".[torch-speech]"
```
(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 `transformers`
library.
Running this command will automatically install `torch` and the most relevant
libraries required for fine-tuning a speech recognition system.
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 in a Python shell.
It verifies that both `transformers` and `datasets` have been correclty installed.
```python
from transformers import AutoModelForCTC, AutoProcessor
from datasets import load_dataset
dummy_dataset = load_dataset("common_voice", "ab", split="test")
model = AutoModelForCTC.from_pretrained("hf-internal-testing/tiny-random-wav2vec2")
model.to("cuda")
processor = AutoProcessor.from_pretrained("hf-internal-testing/tiny-random-wav2vec2")
input_values = processor(dummy_dataset[0]["audio"]["array"], return_tensors="pt", sampling_rate=16_000).input_values
input_values = input_values.to("cuda")
logits = model(input_values).logits
assert logits.shape[-1] == 32
```
## How to finetune an acoustic model
In this section, we show you how to fine-tune a pre-trained [XLS-R Model](https://huggingface.co/docs/transformers/model_doc/xls_r) on the [Common Voice 7 dataset](https://huggingface.co/datasets/mozilla-foundation/common_voice_7_0).
We recommend fine-tuning one of the following pre-trained XLS-R checkpoints:
- [300M parameters version](https://huggingface.co/facebook/wav2vec2-xls-r-300m)
- [1B parameters version](https://huggingface.co/facebook/wav2vec2-xls-r-1b)
- [2B parameters version](https://huggingface.co/facebook/wav2vec2-xls-r-2b)
To begin with, please note that to use the Common Voice dataset, you
have to accept that **your email address** and **username** are shared with the
mozilla-foundation. To get access to the dataset please click on "*Access repository*" [here](https://huggingface.co/datasets/mozilla-foundation/common_voice_7_0).
Next, we recommended that you get familiar with the XLS-R model and its capabilities.
In collaboration with [Fairseq's Wav2Vec2 team](https://github.com/pytorch/fairseq/tree/main/examples/wav2vec),
we've written ["Fine-tuning XLS-R for Multi-Lingual ASR with 🤗 Transformers"](https://huggingface.co/blog/fine-tune-xlsr-wav2vec2) which gives an in-detail explanation of how XLS-R functions and how it can be fine-tuned.
The blog can also be opened and directly fine-tuned in a google colab notebook.
In this section, we will explain how to fine-tune the model on a local machine.
1. **Log in**
To begin with, you should check that you are correctly logged in and that you have `git-lfs` installed so that your fine-tuned model can automatically be uploaded.
Run:
```bash
huggingface-cli login
```
to login. It is recommended to login with your access token that can be found under your hugging face profile (icon in the top right corner on [hf.co](http://hf.co/), then Settings -> Access Tokens -> User Access Tokens -> New Token (if haven't generated one already)
You can then copy-paste this token to log in locally.
2. **Create your model repository**
First, let's make sure that `git-lfs` is correctly installed. To so, simply run:
```bash
git-lfs -v
```
The output should show something like `git-lfs/2.13.2 (GitHub; linux amd64; go 1.15.4)`. If your console states that the `git-lfs` command was not found, please make
sure to install it [here](https://git-lfs.github.com/) or simply via:
```bash
sudo apt-get install git-lfs
```
Now you can create your model repository which will contain all relevant files to
reproduce your training. You can either directly create the model repository on the
Hub (Settings -> New Model) or via the CLI. Here we choose to use the CLI instead.
Assuming that we want to call our model repository *xls-r-ab-test*, we can run the
following command:
```bash
huggingface-cli repo create xls-r-ab-test
```
You can now see the model on the Hub, *e.g.* under https://huggingface.co/hf-test/xls-r-ab-test .
Let's clone the repository so that we can define our training script inside.
```bash
git lfs install
git clone https://huggingface.co/hf-test/xls-r-ab-test
```
3. **Add your training script and `run`-command to the repository**
We encourage participants to add all relevant files for training directly to the
directory so that everything is fully reproducible.
Let's first copy-paste the official training script from our clone
of `transformers` to our just created directory:
```bash
cp ~/transformers/examples/pytorch/speech-recognition/run_speech_recognition_ctc.py ./
```
Next, we'll create a bash file to define the hyper-parameters and configurations
for training. More detailed information on different settings (single-GPU vs. multi-GPU) can be found [here](https://github.com/huggingface/transformers/tree/main/examples/pytorch/speech-recognition#connectionist-temporal-classification).
For demonstration purposes, we will use a dummy XLS-R model `model_name_or_path="hf-test/xls-r-dummy"` on the very low-resource language of "Abkhaz" of [Common Voice 7](https://huggingface.co/datasets/mozilla-foundation/common_voice_7_0): `dataset_config_name="ab"` for just a single epoch.
Before starting to train, let's make sure we have installed all the required libraries. You might want to run:
```bash
pip install -r ~/transformers/examples/pytorch/speech-recognition/requirements.txt
```
Alright, finally we can define the training script. We'll simply use some
dummy hyper-parameters and configurations for demonstration purposes.
Note that we add the flag `--use_auth_token` so that datasets requiring access,
such as [Common Voice 7](https://huggingface.co/datasets/mozilla-foundation/common_voice_7_0) can be downloaded. In addition, we add the `--push_to_hub` flag to make use of the
[Trainers `push_to-hub` functionality](https://huggingface.co/docs/transformers/main/en/main_classes/trainer#transformers.Trainer.push_to_hub) so that your model will be automatically uploaded to the Hub.
Let's copy the following code snippet in a file called `run.sh`
```bash
echo '''python run_speech_recognition_ctc.py \
--dataset_name="mozilla-foundation/common_voice_7_0" \
--model_name_or_path="hf-test/xls-r-dummy" \
--dataset_config_name="ab" \
--output_dir="./" \
--overwrite_output_dir \
--max_steps="10" \
--per_device_train_batch_size="2" \
--learning_rate="3e-4" \
--save_total_limit="1" \
--eval_strategy="steps" \
--text_column_name="sentence" \
--length_column_name="input_length" \
--save_steps="5" \
--layerdrop="0.0" \
--freeze_feature_encoder \
--gradient_checkpointing \
--fp16 \
--group_by_length \
--push_to_hub \
--use_auth_token \
--do_train --do_eval''' > run.sh
```
4. **Start training**
Now all that is left to do is to start training the model by executing the
run file.
```bash
bash run.sh
```
The training should not take more than a couple of minutes.
During the training intermediate saved checkpoints are automatically uploaded to
your model repository as can be seen [on this commit](https://huggingface.co/hf-test/xls-r-ab-test/commit/0eb19a0fca4d7d163997b59663d98cd856022aa6) .
At the end of the training, the [Trainer](https://huggingface.co/docs/transformers/main/en/main_classes/trainer) automatically creates a nice model card and all
relevant files are uploaded.
5. **Tips for real model training**
The above steps illustrate how a model can technically be fine-tuned.
However as you can see on the model card [hf-test/xls-r-ab-test](https://huggingface.co/hf-test/xls-r-ab-test), our demonstration has a very poor performance which is
not surprising given that we trained for just 10 steps on a randomly initialized
model.
For real model training, it is recommended to use one of the actual pre-trained XLS-R models:
- [300M parameters version](https://huggingface.co/facebook/wav2vec2-xls-r-300m)
- [1B parameters version](https://huggingface.co/facebook/wav2vec2-xls-r-1b)
- [2B parameters version](https://huggingface.co/facebook/wav2vec2-xls-r-2b)
Also, the hyper-parameters should be carefully chosen depending on the dataset.
As an example, we will fine-tune the 300M parameters model on Swedish on a single
TITAN RTX 24GB GPU.
The model will be called `"xls-r-300m-sv"`.
Following the above steps we first create the model:
```bash
huggingface-cli repo create xls-r-300m-sv
```
, clone it locally (assuming the `<username>` is `hf-test`)
```bash
git clone hf-test/xls-r-300m-sv
```
, and, define the following hyperparameters for training
```bash
echo '''python run_speech_recognition_ctc.py \
--dataset_name="mozilla-foundation/common_voice_7_0" \
--model_name_or_path="facebook/wav2vec2-xls-r-300m" \
--dataset_config_name="sv-SE" \
--output_dir="./" \
--overwrite_output_dir \
--num_train_epochs="50" \
--per_device_train_batch_size="8" \
--per_device_eval_batch_size="8" \
--gradient_accumulation_steps="4" \
--learning_rate="7.5e-5" \
--warmup_steps="2000" \
--length_column_name="input_length" \
--eval_strategy="steps" \
--text_column_name="sentence" \
--chars_to_ignore , ? . ! \- \; \: \" “ % ‘ ” � — ’ … – \
--save_steps="500" \
--eval_steps="500" \
--logging_steps="100" \
--layerdrop="0.0" \
--activation_dropout="0.1" \
--save_total_limit="3" \
--freeze_feature_encoder \
--feat_proj_dropout="0.0" \
--mask_time_prob="0.75" \
--mask_time_length="10" \
--mask_feature_prob="0.25" \
--mask_feature_length="64" \
--gradient_checkpointing \
--use_auth_token \
--fp16 \
--group_by_length \
--do_train --do_eval \
--push_to_hub''' > run.sh
```
The training takes *ca.* 7 hours and yields a reasonable test word
error rate of 27% as can be seen on the automatically generated [model card](https://huggingface.co/hf-test/xls-r-300m-sv).
The above-chosen hyperparameters probably work quite well on a range of different
datasets and languages but are by no means optimal. It is up to you to find a good set of
hyperparameters.
## How to finetune with OVH cloud
[](https://youtu.be/XkMnYocAEO0) For a more detailed guide on setting up OVHcloud please watch this video: https://youtu.be/XkMnYocAEO0

## How to combine n-gram with acoustic model
Having trained a speech recognition model with CTC as shown in the section above,
one can further improve the model's performance by adding an **n-gram language model**
to the decoding process of the model. By doing so, we are replacing the naive greedy decoding
with **n-gram-boosted** beam search decoding.
N-gram language models can be built on CPU in just a few minutes. *N-gram-boosted* beam search decoding noticeably slows down the
inference time, but also yields significant word error rates improvements - usually between 10-40 %.
You can find an in-detail blog post on how to build an *n-gram* [here](https://huggingface.co/blog/wav2vec2-with-ngram).
The blog post can be opened in a google colab and by adapting three lines of the example for your use case, one can directly
create an *n-gram* in the google colab.
The blog post gives in-detail instructions on how to build an n-gram and how to add it to your trained speech recognition model.
- why one should add an *n-gram* to her/his speech recognition system,
- how to build an *n-gram*, and,
- how to add the built *n-gram* the speech recognition system for seamless decoding
Our previously trained model - [xls-r-300m-sv](https://huggingface.co/hf-test/xls-r-300m-sv) - enjoys a 30% word error rate reduction after
having added an n-gram. As shown in the example of the blog post, we strongly advise participants to upload all files required for combining
the *n-gram* with a trained speech recognition model directly into the same model repository.
## Evaluation
Finally, we have arrived at the most fun part of the challenge - sitting back and
watching the model transcribe audio. If possible, every participant should evaluate
the speech recognition system on the test set of Common Voice 7 and
ideally also on the real-world audio data (if available).
For languages that have neither a Common Voice evaluation dataset nor a real world
evaluation dataset, please contact the organizers on Discord so that we can work
together to find some evaluation data.
As a first step, one should copy the official `eval.py` script to her/his model
repository. Let's use our previously trained [xls-r-300m-sv](https://huggingface.co/hf-test/xls-r-300m-sv) again as an example.
Assuming that we have a clone of the model's repo under `~/xls-r-300m-sv`, we can
copy the `eval.py` script to the repo.
```bash
cp ~/transformers/examples/research_projects/robust-speech-event/eval.py ~/xls-r-300m-sv
```
Next, we should adapt `eval.py` so that it fits our evaluation data. Here it is
important to keep the `eval.py` file in the following format:
- 1. The following input arguments should not be changed and keep their original functionality/meaning (being to load the model and dataset): `"--model_id"`, `"--dataset"`, `"--config"`, `"--split"`. We recommend to not change any of the code written under `if __name__ == "__main__":`.
- 2. The function `def log_results(result: Dataset, args: Dict[str, str])` should also not be changed. The function expects the above names attached to the `args` object as well as a `datasets.Dataset` object, called `result` which includes all predictions and target transcriptions under the names `"predictions"` and `"targets"` respectively.
- 3. All other code can be changed and adapted. Participants are especially invited to change the `def normalize_text(text: str) -> str:` function as this might be a very language and model-training specific function.
- 4. **Important**: It is not allowed to "cheat" in any way when in comes to pre-and postprocessing. In short, "cheating" refers to any of the following:
- a. Somehow giving the model access to the target transcriptions to improve performance. The model is not allowed to use the target transcriptions to generate its predictions.
- b. Pre-processing the target transcriptions in a way that makes the target transcriptions lose their original meaning. This corresponds to what has already been said in [Data and Preprocessing](#data-and-preprocessing) and is somewhat of a grey zone. It means that one should not remove characters that would make a word to lose its meaning. E.g., it is not allowed to replace all `e` in English with `i` and simply make the model learn that `e` and `i` are the same letter for a better word error rate. This would destroy the meaning of words such as `fell -> fill`. However, it is totally fine to normalize (*e.g.* lowercase) all letters, remove punctuation. There can be a lot of language-specific exceptions and in case you are not sure whether your target transcription pre-processing is allowed, please ask on the Discord channel.
Uff, that was a lot of text describing how to make sure your `eval.py` script
is in the correct format. If you have any questions, please ask openly in Discord.
Great, now that we have adapted the `eval.py` script, we can lean back and run the
evaluation.
First, one should evaluate the model on Common Voice 7's test data. This might
already have been done for your acoustic model during training but in case you
added an *n-gram* language model after having fine-tuned the acoustic model, you
should now see a nice improvement.
The command to evaluate our test model [xls-r-300m-sv](https://huggingface.co/hf-test/xls-r-300m-sv) on Common Voice 7's test data is the following:
```bash
cd xls-r-300m-sv
./eval.py --model_id ./ --dataset mozilla-foundation/common_voice_7_0 --config sv-SE --split test --log_outputs
```
To log each of the model's predictions with the target transcriptions, you can just
add the `--log_outputs` flag.
Running this command should automatically create the file:
`mozilla-foundation_common_voice_7_0_sv-SE_test_eval_results.txt` that contains
both the word- and character error rate.
In a few days, we will give everybody access to some real-world audio data for as many languages as possible.
If your language has real-world audio data, it will most likely have audio input
of multiple minutes. 🤗Transformer's [ASR pipeline](https://huggingface.co/docs/transformers/main/en/main_classes/pipelines#transformers.AutomaticSpeechRecognitionPipeline) supports audio chunking out-of-the-box. You only need to specify
how song each audio chunk should be (`chunk_length_s`) and how much audio stride
(`stride_length_s`) each chunk should use.
For more information on the chunking works, please have a look at [this nice blog post](TODO: ).
In the case of `xls-r-300m-sv`, the following command can be run:
```bash
cd xls-r-300m-sv
./eval.py --model_id hf-test/xls-r-300m-sv --dataset <to-be-announced> --config sv --split validation --chunk_length_s 5.0 --stride_length_s 1.0 --log_outputs
```
Great, now you should have successfully evaluated your model. Finally, there is one
**important** thing you should do so that your model is taken into account
for the final evaluation. You should add two tags to your model, one being `robust-speech-event`, one being the ISO code of your chosen language, *e.g.* `"sv"` for the
exemplary model we used above. You can find a list of all available languages and
their ISO code [here](https://huggingface.co/languages).
To add the tags, simply edit the README.md of your model repository and add
```
- "sv"
- "robust-speech-event"
```
under `tags:` as done [here](https://huggingface.co/hf-test/xls-r-300m-sv/commit/a495fd70c96bb7d019729be9273a265c2557345e).
To verify that you've added the tags correctly make sure that your model
appears when clicking on [this link](https://huggingface.co/models?other=robust-speech-event).
Great that's it! This should give you all the necessary information to evaluate
your model. For the final evaluation, we will verify each evaluation result to
determine the final score and thereby the winning models for each language.
The final score is calculated as follows:
```bash
FINAL_SCORE = 1/3 * WER_Common_Voice_7_test + 1/3 * WER_REAL_AUDIO_DEV + 1/3 * WER_REAL_AUDIO_TEST
```
The dataset `WER_REAL_AUDIO_TEST` is hidden and will only be published
at the end of the robust speech challenge.
If there is no real audio data for your language the final score will be
computed solely based on the Common Voice 7 test dataset. If there is also
no Common Voice 7 test dataset for your language, we will see together how to
score your model - if this is the case, please don't be discouraged. We are
especially excited about speech recognition systems of such low-resource
languages and will make sure that we'll decide on a good approach to evaluating
your model.

- Abstract: In this talk, Changhan will present XLS-R, a large-scale model for cross-lingual speech representation learning based on wav2vec 2.0. XLS-R has up to 2B parameters and was trained on nearly half a million hours of publicly available speech audio in 128 languages, an order of magnitude more public data than the largest known prior work. On the CoVoST-2 speech translation benchmark, XLS-R improves the previous state of the art by an average of 7.4 BLEU over 21 translation directions into English. For speech recognition, XLS-R improves over the best known prior work on BABEL, MLS, CommonVoice as well as VoxPopuli, lowering error rates by 14-34% relative on average. XLS-R also sets a new state of the art on VoxLingua107 language identification. The XLS-R team hopes to work together with the open-source community to improve speech processing tasks for many more languages of the world.
## General Tips and Tricks
- Memory efficient training:
In case, you are getting out-of-memory errors on your GPU, we recommend to use
[bitsandbytes](https://github.com/TimDettmers/bitsandbytes) to replace the
native memory-intensive Adam optimizer with the one of `bitsandbytes`. You
can simply run the script `./run_speech_recognition_ctc_bnb.py` provided in this
folder that makes use of `bitsandbytes` instead of the official one.

Author: @yjernite
This folder contains the code for the Long Form Question answering [demo](http://35.226.96.115:8080/) as well as methods to train and use a fully end-to-end Long Form Question Answering system using the [🤗transformers](https://github.com/huggingface/transformers) and [🤗datasets](https://github.com/huggingface/datasets) libraries.
You can use these methods to train your own system by following along the associate [notebook](https://github.com/huggingface/notebooks/blob/master/longform-qa/Long_Form_Question_Answering_with_ELI5_and_Wikipedia.ipynb) or [blog post](https://yjernite.github.io/lfqa.html).

## Whole Word Mask Language Model
These scripts leverage the 🤗 Datasets library and the Trainer API. You can easily customize them to your needs if you
need extra processing on your datasets.
The following examples, will run on a datasets hosted on our [hub](https://huggingface.co/datasets) or with your own
text files for training and validation. We give examples of both below.
The BERT authors released a new version of BERT using Whole Word Masking in May 2019. Instead of masking randomly
selected tokens (which may be part of words), they mask randomly selected words (masking all the tokens corresponding
to that word). This technique has been refined for Chinese in [this paper](https://arxiv.org/abs/1906.08101).
To fine-tune a model using whole word masking, use the following script:
```bash
python run_mlm_wwm.py \
--model_name_or_path FacebookAI/roberta-base \
--dataset_name wikitext \
--dataset_config_name wikitext-2-raw-v1 \
--do_train \
--do_eval \
--output_dir /tmp/test-mlm-wwm
```
For Chinese models, we need to generate a reference files (which requires the ltp library), because it's tokenized at
the character level.
**Q :** Why a reference file?
**A :** Suppose we have a Chinese sentence like: `我喜欢你` The original Chinese-BERT will tokenize it as
`['我','喜','欢','你']` (character level). But `喜欢` is a whole word. For whole word masking proxy, we need a result
like `['我','喜','##欢','你']`, so we need a reference file to tell the model which position of the BERT original token
should be added `##`.
**Q :** Why LTP ?
**A :** Cause the best known Chinese WWM BERT is [Chinese-BERT-wwm](https://github.com/ymcui/Chinese-BERT-wwm) by HIT.
It works well on so many Chines Task like CLUE (Chinese GLUE). They use LTP, so if we want to fine-tune their model,
we need LTP.
You could run the following:
```bash
export TRAIN_FILE=/path/to/train/file
export LTP_RESOURCE=/path/to/ltp/tokenizer
export BERT_RESOURCE=/path/to/bert/tokenizer
export SAVE_PATH=/path/to/data/ref.txt
python run_chinese_ref.py \
--file_name=$TRAIN_FILE \
--ltp=$LTP_RESOURCE \
--bert=$BERT_RESOURCE \
--save_path=$SAVE_PATH
```
Then you can run the script like this:
```bash
export TRAIN_FILE=/path/to/train/file
export VALIDATION_FILE=/path/to/validation/file
export TRAIN_REF_FILE=/path/to/train/chinese_ref/file
export VALIDATION_REF_FILE=/path/to/validation/chinese_ref/file
export OUTPUT_DIR=/tmp/test-mlm-wwm
python run_mlm_wwm.py \
--model_name_or_path FacebookAI/roberta-base \
--train_file $TRAIN_FILE \
--validation_file $VALIDATION_FILE \
--train_ref_file $TRAIN_REF_FILE \
--validation_ref_file $VALIDATION_REF_FILE \
--do_train \
--do_eval \
--output_dir $OUTPUT_DIR
```
**Note1:** On TPU, you should the flag `--pad_to_max_length` to make sure all your batches have the same length.
**Note2:** And if you have any questions or something goes wrong when running this code, don't hesitate to pin @wlhgtc.

Authors: @patrickvonplaten and @lhoestq
Aimed at tackling the knowledge-intensive NLP tasks (think tasks a human wouldn't be expected to solve without access to external knowledge sources), RAG models are seq2seq models with access to a retrieval mechanism providing relevant context documents at training and evaluation time.
A RAG model encapsulates two core components: a question encoder and a generator.
During a forward pass, we encode the input with the question encoder and pass it
to the retriever to extract relevant context documents. The documents are then prepended to the input.
Such contextualized inputs are passed to the generator.
Read more about RAG at https://arxiv.org/abs/2005.11401.
# Note
⚠️ This project should be run with pytorch-lightning==1.3.1 which has a potential security vulnerability
# Finetuning
Our finetuning logic is based on scripts from [`examples/legacy/seq2seq`](https://github.com/huggingface/transformers/tree/main/examples/legacy/seq2seq). We accept training data in the same format as specified there - we expect a directory consisting of 6 text files:
```bash
train.source
train.target
val.source
val.target
test.source
test.target
```
A sample finetuning command (run ` ./examples/research_projects/rag/finetune_rag.py --help` to list all available options):
```bash
python examples/research_projects/rag/finetune_rag.py \
--data_dir $DATA_DIR \
--output_dir $OUTPUT_DIR \
--model_name_or_path $MODEL_NAME_OR_PATH \
--model_type rag_sequence \
--fp16 \
--gpus 8
```
We publish two `base` models which can serve as a starting point for finetuning on downstream tasks (use them as `model_name_or_path`):
- [`facebook/rag-sequence-base`](https://huggingface.co/facebook/rag-sequence-base) - a base for finetuning `RagSequenceForGeneration` models,
- [`facebook/rag-token-base`](https://huggingface.co/facebook/rag-token-base) - a base for finetuning `RagTokenForGeneration` models.
The `base` models initialize the question encoder with [`facebook/dpr-question_encoder-single-nq-base`](https://huggingface.co/facebook/dpr-question_encoder-single-nq-base) and the generator with [`facebook/bart-large`](https://huggingface.co/facebook/bart-large).
If you would like to initialize finetuning with a base model using different question encoder and generator architectures, you can build it with a consolidation script, e.g.:
```bash
python examples/research_projects/rag/consolidate_rag_checkpoint.py \
--model_type rag_sequence \
--generator_name_or_path facebook/bart-large-cnn \
--question_encoder_name_or_path facebook/dpr-question_encoder-single-nq-base \
--dest path/to/checkpoint
```
You will then be able to pass `path/to/checkpoint` as `model_name_or_path` to the `finetune_rag.py` script.
## Document Retrieval
When running distributed fine-tuning, each training worker needs to retrieve contextual documents
for its input by querying a index loaded into memory. RAG provides two implementations for document retrieval,
one with [`torch.distributed`](https://pytorch.org/docs/stable/distributed.html) communication package and the other
with [`Ray`](https://docs.ray.io/en/master/).
This option can be configured with the `--distributed_retriever` flag which can either be set to `pytorch` or `ray`.
By default this flag is set to `pytorch`.
For the Pytorch implementation, only training worker 0 loads the index into CPU memory, and a gather/scatter pattern is used
to collect the inputs from the other training workers and send back the corresponding document embeddings.
For the Ray implementation, the index is loaded in *separate* process(es). The training workers randomly select which
retriever worker to query. To use Ray for distributed retrieval, you have to set the `--distributed_retriever` arg to `ray`.
To configure the number of retrieval workers (the number of processes that load the index), you can set the `num_retrieval_workers` flag.
Also make sure to start the Ray cluster before running fine-tuning.
```bash
# Start a single-node Ray cluster.
ray start --head
python examples/research_projects/rag/finetune_rag.py \
--data_dir $DATA_DIR \
--output_dir $OUTPUT_DIR \
--model_name_or_path $MODEL_NAME_OR_PATH \
--model_type rag_sequence \
--fp16 \
--gpus 8
--distributed_retriever ray \
--num_retrieval_workers 4
# Stop the ray cluster once fine-tuning has finished.
ray stop
```
Using Ray can lead to retrieval speedups on multi-GPU settings since multiple processes load the index rather than
just the rank 0 training worker. Using Ray also allows you to load the index on GPU since the index is loaded on a separate
processes than the model, while with pytorch distributed retrieval, both are loaded in the same process potentially leading to GPU OOM.
# Evaluation
Our evaluation script enables two modes of evaluation (controlled by the `eval_mode` argument): `e2e` - end2end evaluation, returns EM (exact match) and F1 scores calculated for the downstream task and `retrieval` - which returns precision@k of the documents retrieved for provided inputs.
The evaluation script expects paths to two files:
- `evaluation_set` - a path to a file specifying the evaluation dataset, a single input per line.
- `gold_data_path` - a path to a file contaning ground truth answers for datapoints from the `evaluation_set`, a single output per line. Check below for expected formats of the gold data files.
## Retrieval evaluation
For `retrieval` evaluation, we expect a gold data file where each line will consist of a tab-separated list of document titles constituting positive contexts for respective datapoints from the `evaluation_set`. E.g. given a question `who sings does he love me with reba` in the `evaluation_set`, a respective ground truth line could look as follows:
```
Does He Love You Does He Love You Red Sandy Spika dress of Reba McEntire Greatest Hits Volume Two (Reba McEntire album) Shoot for the Moon (album)
```
We demonstrate how to evaluate retrieval against DPR evaluation data. You can download respective files from links listed [here](https://github.com/facebookresearch/DPR/blob/master/data/download_data.py#L39-L45).
1. Download and unzip the gold data file. We use the `biencoder-nq-dev` from https://dl.fbaipublicfiles.com/dpr/data/retriever/biencoder-nq-dev.json.gz.
```bash
wget https://dl.fbaipublicfiles.com/dpr/data/retriever/biencoder-nq-dev.json.gz && gzip -d biencoder-nq-dev.json.gz
```
2. Parse the unziped file using the `parse_dpr_relevance_data.py`
```bash
mkdir output # or wherever you want to save this
python examples/research_projects/rag/parse_dpr_relevance_data.py \
--src_path biencoder-nq-dev.json \
--evaluation_set output/biencoder-nq-dev.questions \
--gold_data_path output/biencoder-nq-dev.pages
```
3. Run evaluation:
```bash
python examples/research_projects/rag/eval_rag.py \
--model_name_or_path facebook/rag-sequence-nq \
--model_type rag_sequence \
--evaluation_set output/biencoder-nq-dev.questions \
--gold_data_path output/biencoder-nq-dev.pages \
--predictions_path output/retrieval_preds.tsv \
--eval_mode retrieval \
--k 1
```
```bash
# EXPLANATION
python examples/research_projects/rag/eval_rag.py \
--model_name_or_path facebook/rag-sequence-nq \ # model name or path of the model we're evaluating
--model_type rag_sequence \ # RAG model type (rag_token or rag_sequence)
--evaluation_set output/biencoder-nq-dev.questions \ # an input dataset for evaluation
--gold_data_path poutput/biencoder-nq-dev.pages \ # a dataset containing ground truth answers for samples from the evaluation_set
--predictions_path output/retrieval_preds.tsv \ # name of file where predictions will be stored
--eval_mode retrieval \ # indicates whether we're performing retrieval evaluation or e2e evaluation
--k 1 # parameter k for the precision@k metric
```
## End-to-end evaluation
We support two formats of the gold data file (controlled by the `gold_data_mode` parameter):
- `qa` - where a single line has the following format: `input [tab] output_list`, e.g.:
```
who is the owner of reading football club ['Xiu Li Dai', 'Dai Yongge', 'Dai Xiuli', 'Yongge Dai']
```
- `ans` - where a single line contains a single expected answer, e.g.:
```
Xiu Li Dai
```
Predictions of the model for the samples from the `evaluation_set` will be saved under the path specified by the `predictions_path` parameter.
If this path already exists, the script will use saved predictions to calculate metrics.
Add `--recalculate` parameter to force the script to perform inference from scratch.
An example e2e evaluation run could look as follows:
```bash
python examples/research_projects/rag/eval_rag.py \
--model_name_or_path facebook/rag-sequence-nq \
--model_type rag_sequence \
--evaluation_set path/to/test.source \
--gold_data_path path/to/gold_data \
--predictions_path path/to/e2e_preds.txt \
--eval_mode e2e \
--gold_data_mode qa \
--n_docs 5 \ # You can experiment with retrieving different number of documents at evaluation time
--print_predictions \
--recalculate \ # adding this parameter will force recalculating predictions even if predictions_path already exists
```
# Use your own knowledge source
By default, RAG uses the English Wikipedia as a knowledge source, known as the 'wiki_dpr' dataset.
With `use_custom_knowledge_dataset.py` you can build your own knowledge source, *e.g.* for RAG.
For instance, if documents are serialized as tab-separated csv files with the columns "title" and "text", one can use `use_own_knowledge_dataset.py` as follows:
```bash
python examples/research_projects/rag/use_own_knowledge_dataset.py \
--csv_path path/to/my_csv \
--output_dir path/to/my_knowledge_dataset \
```
The created outputs in `path/to/my_knowledge_dataset` can then be used to finetune RAG as follows:
```bash
python examples/research_projects/rag/finetune_rag.py \
--data_dir $DATA_DIR \
--output_dir $OUTPUT_DIR \
--model_name_or_path $MODEL_NAME_OR_PATH \
--model_type rag_sequence \
--fp16 \
--gpus 8
--index_name custom
--passages_path path/to/data/my_knowledge_dataset
--index_path path/to/my_knowledge_dataset_hnsw_index.faiss
```

mavonic_private_repos/transformers/examples/research_projects/rag | mavonic_private_repos/transformers/examples/research_projects/rag/test_data/my_knowledge_dataset.csv | Aaron Aaron Aaron ( or ; "Ahärôn") is a prophet, high priest, and the brother of Moses in the Abrahamic religions. Knowledge of Aaron, along with his brother Moses, comes exclusively from religious texts, such as the Bible and Quran. The Hebrew Bible relates that, unlike Moses, who grew up in the Egyptian royal court, Aaron and his elder sister Miriam remained with their kinsmen in the eastern border-land of Egypt (Goshen). When Moses first confronted the Egyptian king about the Israelites, Aaron served as his brother's spokesman ("prophet") to the Pharaoh. Part of the Law (Torah) that Moses received from God at Sinai granted Aaron the priesthood for himself and his male descendants, and he became the first High Priest of the Israelites. Aaron died before the Israelites crossed the North Jordan river and he was buried on Mount Hor (Numbers 33:39; Deuteronomy 10:6 says he died and was buried at Moserah). Aaron is also mentioned in the New Testament of the Bible. According to the Book of Exodus, Aaron first functioned as Moses' assistant. Because Moses complained that he could not speak well, God appointed Aaron as Moses' "prophet" (Exodus 4:10-17; 7:1). At the command of Moses, he let his rod turn into a snake. Then he stretched out his rod in order to bring on the first three plagues. After that, Moses tended to act and speak for himself. During the journey in the wilderness, Aaron was not always prominent or active. At the battle with Amalek, he was chosen with Hur to support the hand of Moses that held the "rod of God". When the revelation was given to Moses at biblical Mount Sinai, he headed the elders of Israel who accompanied Moses on the way to the summit.
"Pokémon" Pokémon , also known as in Japan, is a media franchise managed by The Pokémon Company, a Japanese consortium between Nintendo, Game Freak, and Creatures. The franchise copyright is shared by all three companies, but Nintendo is the sole owner of the trademark. The franchise was created by Satoshi Tajiri in 1995, and is centered on fictional creatures called "Pokémon", which humans, known as Pokémon Trainers, catch and train to battle each other for sport. The English slogan for the franchise is "Gotta Catch 'Em All". Works within the franchise are set in the Pokémon universe. The franchise began as "Pokémon Red" and "Green" (released outside of Japan as "Pokémon Red" and "Blue"), a pair of video games for the original Game Boy that were developed by Game Freak and published by Nintendo in February 1996. "Pokémon" has since gone on to become the highest-grossing media franchise of all time, with over in revenue up until March 2017. The original video game series is the second best-selling video game franchise (behind Nintendo's "Mario" franchise) with more than 300million copies sold and over 800million mobile downloads. In addition, the "Pokémon" franchise includes the world's top-selling toy brand, the top-selling trading card game with over 25.7billion cards sold, an anime television series that has become the most successful video game adaptation with over 20 seasons and 1,000 episodes in 124 countries, as well as an anime film series, a , books, manga comics, music, and merchandise. The franchise is also represented in other Nintendo media, such as the "Super Smash Bros." series. In November 2005, 4Kids Entertainment, which had managed the non-game related licensing of "Pokémon", announced that it had agreed not to renew the "Pokémon" representation agreement. The Pokémon Company International oversees all "Pokémon" licensing outside Asia. | 0 |
mavonic_private_repos/transformers/examples/research_projects | mavonic_private_repos/transformers/examples/research_projects/wav2vec2/FINE_TUNE_XLSR_WAV2VEC2.md | # Fine-Tuning week of XLSR-Wav2Vec2 on 60 languages 🌍
Welcome to the fine-tuning week! The goal of this week is to have state-of-the-art automatic speech recognition (ASR) models in as many languages as possible. The fine-tuning week ends on Friday, the 26th March at midnight PST time.
Participants are encouraged to fine-tune the pretrained [facebook/wav2vec2-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53) checkpoint on one or more of the 60 languages of [Common Voice dataset](https://commonvoice.mozilla.org/en/datasets).
Furthermore, it is very much appreciated if participants fine-tune XLSR-Wav2Vec2 on a language that is not included in the Common Voice dataset.
All fine-tuned models uploaded until Friday, the 26th March midnight PST, will be taken into account for competition, and the best model per language will be awarded a prize if the best model performs reasonably well.
The testing data to evaluate the models will be the official [Common Voice dataset](https://commonvoice.mozilla.org/en/datasets) *`test data`* of version 6.1. Again, participants are very much encouraged to fine-tune XLSR-Wav2Vec2 on languages that are not found in the Common Voice dataset since those languages are even more likely to be underrepresented in the speech community.
Each model fine-tuned on a language not found in Common Voice, will be evaluated by the Hugging Face team after Friday, the 26th March at midnight PST, and if the model performs reasonably well, the model receives a prize as well.
For more information on which data can be used for training, how the models are evaluated exactly, and what type of data preprocessing can be used, please see ["Training and Evaluation Rules"](#training-and-evaluation-rules).
**Please keep in mind:**
The spirit of the fine-tuning week is to provide state-of-the-art speech recognition in as many languages as possible to the community!
So while we encourage healthy competition between people/groups of the same language so that better results are obtained, it is extremely important that we help each other and share our insights with the whole team/community.
What matters in the end is what has been achieved by the team as a whole during the fine-tuning week.
That being said, we strongly encourage people to share tips & tricks on the forum or Slack, help each other when team members encounter bugs, and work in groups.
To make it easier to share and help, forum threads have been created under the name {language} ASR: Fine-Tuning Wav2Vec2, e.g. here.
It is very much possible that prizes will be given to groups of people instead of individuals. Also, don't hesitate to ask questions, propose improvements to the organization, to the material given to participants, etc...🤗

## How to fine tune XLSR Wav2Vec2
This chapter gives an in-detail explanation of how to fine-tune [Facebook's multi-lingual Wav2vec2](https://huggingface.co/facebook/wav2vec2-large-xlsr-53) on any language of the [Common Voice dataset](https://commonvoice.mozilla.org/en/datasets).
Two possible setups can be used to fine-tune Wav2Vec2. The easiest setup is to simply use [google colab](https://colab.research.google.com/). It is possible to train the full model in a *free* google colab, but it is recommended to use google colab pro since it is more stable.
The other option is to run a script locally. While this can be more difficult to set up, it also means that you have more control over the training run and probably access to better GPUs than you would have in a google colab.
For small datasets, it is usually totally sufficient to train your model
in a google colab. For larger and thus more memory-intensive datasets, it is probably
better to fine-tune the model locally.
For each option, we explain in detail how to fine-tune XLSR-Wav2Vec2 in the following.
### Google colab setup
**Note**: Instead of reading the following section, you can simply watch [this](https://www.youtube.com/watch?v=UynYn2C3tI0&ab_channel=PatrickvonPlaten) video, where Patrick explains how to adapt the google colab for your specific language.
**1.**: If you plan on training XLSR-Wav2Vec2 in a google colab, you should first make sure to have a valid gmail account. You can sign up for a gmail account [here](https://accounts.google.com/signup/v2/webcreateaccount?hl=en&flowName=GlifWebSignIn&flowEntry=SignUp).
Having successfully signed up for gmail, you can now sign in to your account to make sure you are logged in when opening new tabs in your browser.
**2.**: Next, head over to the official [Fine-Tune XLSR-Wav2Vec2 with 🤗 Transformes](https://colab.research.google.com/github/patrickvonplaten/notebooks/blob/master/Fine_Tune_XLSR_Wav2Vec2_on_Turkish_ASR_with_%F0%9F%A4%97_Transformers.ipynb) google colab. The first thing you should do is to make a copy of it - click `->File->Save a copy in Drive`. This should save a copy of the google colab in your google drive.
**3.**: Now it is highly recommended to carefully read the google colab without running the cells yet.
You should get an understanding of the model is trained and what you will have to change when training the model in a different language.
Having done so, you can again head over to [Common Voice](https://commonvoice.mozilla.org/en/datasets) and pick a language you want to fine-tune [facebook/wav2vec2-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53) on. Make sure you remember the language code (For each language, you can find it under the field "*Version*". It corresponds to **all characters before the first underscore**. *E.g.* for Greek it is *el*, while for Irish it is *ga-IE*.
**4.**: Now you should replace the language code used for the demo of this colab, being *tr* for Turkish with the language code corresponding to the language you just chose in the **second** cell of the google colab. This will load the correct data for your language.
**5.**: It is time to start running the google colab! Make sure that you have selected "GPU" as your runtime environment and you can start running the cells one-by-one. Make sure you attentively read the text between the cells to understand what is happening and to eventually correct the cells to improve the fine-tuning script for your language. Things you might want to improve/change:
- Data loading. It is very much recommended to use more than just the official training data of the Common Voice dataset. If you find more data on the internet, feel free to use it! Check out the section ["How to combined multiple datasets into one"](#how-to-combine-multiple-datasets-into-one)
- Data Processing. You should adapt the data processing to your specific language. In data processing, you should make the data more uniform so that it will be easier for the model to learn how to classify speech in your data. Here it can be really helpful to be proficient in the language to know what can be done to simplify the language without changing the meaning.
Data processing methods include, but are not limited to:
- Normalizing your data. Make sure all characters are lower-cased.
- Remove typographical symbols and punctuation marks. See a list [here](https://en.wikipedia.org/wiki/List_of_typographical_symbols_and_punctuation_marks). Be careful to not remove punctuation marks that can change the meaning of the sentence. *E.g.* you should not remove the single quotation mark `'` in English, as it would change the words `"it's"` to `"its"` which is a different word and has thus a different meaning. For more tips on data processing see ["How to effectively preprocess the data"](#how-to-effectively-preprocess-the-data")
- Hyperparameter Tuning. Depending on the size of the data you should probably change the hyperparameters of the google colab. You can change any parameter you like. For more tips and tricks see ["How to do hyperparameter tuning for my language"](#how-to-do-hyperparameter-tuning-for-my-language)
When running the google colab make sure that you uncomment the cell corresponding to mounting your google drive to the colab. This cell looks as follows:
```python
# from google.colab import drive
# drive.mount('/content/gdrive/')
```
Uncomment it, run it, and follow the instructions to mount your google drive. This way you can be sure that the model parameters and created tokenizer & feature extractor files are saved in **your** google drive.
Also, make sure that you uncomment the cells corresponding to save the preprocessing files and trained model weights to your drive. Otherwise, you might lose a trained model if you google crashes. You should change the name of your model from `wav2vec2-large-xlsr-turkish-demo` to `wav2vec2-large-xlsr-{your_favorite_name}`.
Those cells correspond to:
```python
# processor.save_pretrained("/content/gdrive/MyDrive/wav2vec2-large-xlsr-turkish-demo")
```
and the line:
```python
output_dir="/content/gdrive/MyDrive/wav2vec2-large-xlsr-turkish-demo",
```
further below (which should already be uncommented).
Having finished the training you should find the following files/folders under the folder `wav2vec2-large-xlsr-{your_favorite_name}` in your google drive:
- `preprocessor_config.json` - the parameters of the feature extractor
- `special_tokens_map.json` - the special token map of the tokenizer
- `tokenizer_config.json` - the parameters of the tokenizer
- `vocab.json` - the vocabulary of the tokenizer
- `checkpoint-{...}/` - the saved checkpoints saved during training. Each checkpoint should contain the files: `config.json`, `optimizer.pt`, `pytorch_model.bin`, `scheduler.pt`, `training_args.bin`. The files `config.json` and `pytorch_model.bin` define your model.
If you are happy with your training results it is time to upload your model!
Download the following files to your local computer: **`preprocessor_config.json`, `special_tokens_map.json`, `tokenizer_config.json`, `vocab.json`, `config.json`, `pytorch_model.bin`**. Those files fully define a XLSR-Wav2Vec2 model checkpoint.
Awesome you have successfully trained a XLSR-Wav2Vec2 model 😎. Now you can jump to the section ["How to upload my trained checkpoint"](#how-to-upload-my-trained-checkpoint)
### Local machine
We have provided `run_common_voice.py` script to run fine-tuning on local machine. The script is similar to the colab but allows you to launch training using command line, save and continue training from previous checkpoints and launch training on multiple GPUs.
For bigger datasets, we recommend to train Wav2Vec2 locally instead of in a google colab.
1. To begin with, we should clone transformers localy and install all the required packages.
First, you need to clone the `transformers` repo with:
```bash
$ git clone https://github.com/huggingface/transformers.git
```
Second, head over to the `examples/research_projects/wav2vec2` directory, where the `run_common_voice.py` script is located.
```bash
$ cd transformers/examples/research_projects/wav2vec2
```
Third, install the required packages. The
packages are listed in the `requirements.txt` file and can be installed with
```bash
$ pip install -r requirements.txt
```
**Note**: Installing the latest version of `torchaudio` will also upgrade `torch` to it's latest stable version. If you are using specific version of `torch` then make sure
to use the correct `torchaudio` version compatible with your version of `torch`. By default the `requirements.txt` will install the latest version of `torchaudio`.
2. Next, take a look at the `run_common_voice.py` script to get an understanding of how it works. In short the script does the following:
- Load the given common voice dataset
- Create vocab for the language
- Load the model with given hyperparameters
- Pre-process the dataset to input into the model
- Run training
- Run evaluation
3. The following examples show how you can launch fine-tuning for the common voice dataset.
Here we will run the script on the *Turkish* Common Voice dataset for demonstration purposes.
**To lanuch fine-tuninig on a single GPU:**
```bash
python run_common_voice.py \
--model_name_or_path="facebook/wav2vec2-large-xlsr-53" \
--dataset_config_name="tr" \ # use this argument to specify the language code
--output_dir=./wav2vec2-large-xlsr-turkish-demo \
--overwrite_output_dir \
--num_train_epochs="5" \
--per_device_train_batch_size="16" \
--learning_rate="3e-4" \
--warmup_steps="500" \
--eval_strategy="steps" \
--save_steps="400" \
--eval_steps="400" \
--logging_steps="400" \
--save_total_limit="3" \
--freeze_feature_extractor \
--feat_proj_dropout="0.0" \
--layerdrop="0.1" \
--gradient_checkpointing \
--fp16 \
--group_by_length \
--do_train --do_eval
```
**To lanuch fine-tuninig on multiple GPUs:**
```bash
python -m torch.distributed.launch \
--nproc_per_node 4 run_common_voice.py \
--model_name_or_path="facebook/wav2vec2-large-xlsr-53" \
--dataset_config_name="tr" \ # use this argument to specify the language code
--output_dir=./wav2vec2-large-xlsr-turkish-demo \
--overwrite_output_dir \
--num_train_epochs="5" \
--per_device_train_batch_size="16" \
--learning_rate="3e-4" \
--warmup_steps="500" \
--eval_strategy="steps" \
--save_steps="400" \
--eval_steps="400" \
--logging_steps="400" \
--save_total_limit="3" \
--freeze_feature_extractor \
--feat_proj_dropout="0.0" \
--layerdrop="0.1" \
--gradient_checkpointing \
--fp16 \
--group_by_length \
--do_train --do_eval
```
The above command will launch the training on 4 GPUs. Use the `--nproc_per_node` option to specify the number of GPUs.
Once the training is finished, the model and checkpoints will be saved under the directory specified by the `--output_dir` argument.
4. The script also allows you to resume training from the last saved checkpoint. To resume training from last saved checkpoint remove the `--overwrite_output_dir` option and run the same command again. And to continue training from a specific checkpoint, keep the `--overwrite_output_dir`
option and pass the path of the checkpoint as `--model_name_or_path`.
As the script is based on the `Trainer` API, refer to the [Trainer docs](https://huggingface.co/transformers/main_classes/trainer.html) for more information about ``Trainer`` and ``TrainingArguments``.
[OVH cloud](https://www.ovh.com/world/) has generously offered free compute for this sprint. Please refer to [this video](https://www.youtube.com/watch?v=2hlkWAESMk8&ab_channel=Databuzzword) to get started with OVH.
## How to upload my trained checkpoint
To upload your trained checkpoint, you have to create a new model repository on the 🤗 model hub, from this page: https://huggingface.co/new
> You can also follow the more in-depth instructions [here](https://huggingface.co/transformers/model_sharing.html) if needed.
Having created your model repository on the hub, you should clone it locally:
```bash
git lfs install
git clone https://huggingface.co/username/your-model-name
```
Then and add the following files that fully define a XLSR-Wav2Vec2 checkpoint into the repository. You should have added the following files.
- `preprocessor_config.json`
- `special_tokens_map.json`
- `tokenizer_config.json`
- `vocab.json`
- `config.json`
- `pytorch_model.bin`
Having added the above files, you should run the following to push files to your model repository.
```bash
git add . && git commit -m "Add model files" && git push
```
The next **very important** step is to create the model card. For people to use your fine-tuned
model it is important to understand:
- What kind of model is it?
- What is your model useful for?
- What data was your model trained on?
- How well does your model perform?
All these questions should be answered in a model card which is the first thing people see when
visiting your model on the hub under `https://huggingface.co/{your_username}/{your_modelname}`.
**Note**:
It is extremely important that you add this model card or else we cannot find your model and thus cannot take the model into
account for the final evaluation.
### How to create the readme
The model card is written in markdown (`.md`) and should be added by simply clicking on the "Add model card" button which is found on the top right corner.
You are encouraged to copy-paste the following template into your model card.
**Make sure that** instead of copying the output of the markdown file you copy the **raw** version of the following part.
To get the raw version of this file, simply click on the "`raw`" button on the top right corner of this file next to "`blame`" and copy everything below the marker.
Make sure that you read and consequently remove all #TODO: statements from the model card.

resampler = torchaudio.transforms.Resample(48_000, 16_000)
# Preprocessing the datasets.
# We need to read the aduio files as arrays
def speech_file_to_array_fn(batch):
speech_array, sampling_rate = torchaudio.load(batch["path"])
batch["speech"] = resampler(speech_array).squeeze().numpy()
return batch
test_dataset = test_dataset.map(speech_file_to_array_fn)
inputs = processor(test_dataset[:2]["speech"], sampling_rate=16_000, return_tensors="pt", padding=True)
with torch.no_grad():
logits = model(inputs.input_values, attention_mask=inputs.attention_mask).logits

## Training
The Common Voice `train`, `validation`, and ... datasets were used for training as well as ... and ... # TODO: adapt to state all the datasets that were used for training.
The script used for training can be found [here](...) # TODO: fill in a link to your training script here. If you trained your model in a colab, simply fill in the link here. If you trained the model locally, it would be great if you could upload the training script on github and paste the link here.
=======================To here===============================>
Your model in then available under *huggingface.co/{your_username}/{your_chosen_xlsr-large_model_name}* for everybody to use 🎉.
## How to evaluate my trained checkpoint
Having uploaded your model, you should now evaluate your model in a final step. This should be as simple as
copying the evaluation code of your model card into a python script and running it. Make sure to note
the final result on the model card **both** under the YAML tags at the very top **and** below your evaluation code under "Test Results".
## Rules of training and evaluation
In this section, we will quickly go over what data is allowed to be used as training
data, what kind of data preprocessing is allowed be used, and how the model should be evaluated.
To make it very simple regarding the first point: **All data except the official common voice `test` data set can be used as training data**. For models trained in a language that is not included in Common Voice, the author of the model is responsible to
leave a reasonable amount of data for evaluation.
Second, the rules regarding the preprocessing are not that as straight-forward. It is allowed (and recommended) to
normalize the data to only have lower-case characters. It is also allowed (and recommended) to remove typographical
symbols and punctuation marks. A list of such symbols can *e.g.* be fonud [here](https://en.wikipedia.org/wiki/List_of_typographical_symbols_and_punctuation_marks) - however here we already must be careful. We should **not** remove a symbol that
would change the meaning of the words, *e.g.* in English, we should not remove the single quotation mark `'` since it
would change the meaning of the word `"it's"` to `"its"` which would then be incorrect. So the golden rule here is to
not remove any characters that could change the meaning of a word into another word. This is not always obvious and should
be given some consideration. As another example, it is fine to remove the "Hypen-minus" sign "`-`" since it doesn't change the
meaninng of a word to another one. *E.g.* "`fine-tuning`" would be changed to "`finetuning`" which has still the same meaning.
Since those choices are not always obvious when in doubt feel free to ask on Slack or even better post on the forum, as was
done, *e.g.* [here](https://discuss.huggingface.co/t/spanish-asr-fine-tuning-wav2vec2/4586).
## Tips and tricks
This section summarizes a couple of tips and tricks across various topics. It will continously be updated during the week.
### How to combine multiple datasets into one

## Further reading material
It is recommended that take some time to read up on how Wav2vec2 works in theory.
Getting a better understanding of the theory and the inner mechanisms of the model often helps when fine-tuning the model.
**However**, if you don't like reading blog posts/papers, don't worry - it is by no means necessary to go through the theory to fine-tune Wav2Vec2 on your language of choice.
If you are interested in learning more about the model though, here are a couple of resources that are important to better understand Wav2Vec2:
- [Facebook's Wav2Vec2 blog post](https://ai.facebook.com/blog/wav2vec-state-of-the-art-speech-recognition-through-self-supervision/)
- [Official Wav2Vec2 paper](https://arxiv.org/abs/2006.11477)
- [Official XLSR Wav2vec2 paper](https://arxiv.org/pdf/2006.13979.pdf)
- [Hugging Face Blog](https://huggingface.co/blog/fine-tune-xlsr-wav2vec2)
- [How does CTC (Connectionist Temporal Classification) work](https://distill.pub/2017/ctc/)
It helps to have a good understanding of the following points:
- How was XLSR-Wav2Vec2 pretrained? -> Feature vectors were masked and had to be predicted by the model; very similar in spirit to masked language model of BERT.
- What parts of XLSR-Wav2Vec2 are responsible for what? What is the feature extractor part used for? -> extract feature vectors from the 1D raw audio waveform; What is the transformer part doing? -> mapping feature vectors to contextualized feature vectors; ...
- What part of the model needs to be fine-tuned? -> The pretrained model **does not** include a language head to classify the contextualized features to letters. This is randomly initialized when loading the pretrained checkpoint and has to be fine-tuned. Also, note that the authors recommend to **not** further fine-tune the feature extractor.
- What data was used to XLSR-Wav2Vec2? The checkpoint we will use for further fine-tuning was pretrained on **53** languages.
- What languages are considered to be similar by XLSR-Wav2Vec2? In the official [XLSR Wav2Vec2 paper](https://arxiv.org/pdf/2006.13979.pdf), the authors show nicely which languages share a common contextualized latent space. It might be useful for you to extend your training data with data of other languages that are considered to be very similar by the model (or you).
## FAQ
- Can a participant fine-tune models for more than one language?
Yes! A participant can fine-tune models in as many languages she/he likes
- Can a participant use extra data (apart from the common voice data)?
Yes! All data except the official common voice `test data` can be used for training.
If a participant wants to train a model on a language that is not part of Common Voice (which
is very much encouraged!), the participant should make sure that some test data is held out to
make sure the model is not overfitting.
- Can we fine-tune for high-resource languages?
Yes! While we do not really recommend people to fine-tune models in English since there are
already so many fine-tuned speech recognition models in English. However, it is very much
appreciated if participants want to fine-tune models in other "high-resource" languages, such
as French, Spanish, or German. For such cases, one probably needs to train locally and apply
might have to apply tricks such as lazy data loading (check the ["Lazy data loading"](#how-to-do-lazy-data-loading) section for more details).

follow the new instructions of fine-tuning Wav2Vec2 [here](https://github.com/huggingface/transformers/blob/main/examples/pytorch/speech-recognition/README.md)
## Fine-tuning Wav2Vec2
The `run_asr.py` script allows one to fine-tune pretrained Wav2Vec2 models that can be found [here](https://huggingface.co/models?search=facebook/wav2vec2).
This finetuning script can also be run as a google colab [TODO: here]( ).
### Fine-Tuning with TIMIT
Let's take a look at the [script](./finetune_base_timit_asr.sh) used to fine-tune [wav2vec2-base](https://huggingface.co/facebook/wav2vec2-base)
with the [TIMIT dataset](https://huggingface.co/datasets/timit_asr):
```bash
#!/usr/bin/env bash
python run_asr.py \
--output_dir="./wav2vec2-base-timit-asr" \
--num_train_epochs="30" \
--per_device_train_batch_size="20" \
--per_device_eval_batch_size="20" \
--eval_strategy="steps" \
--save_steps="500" \
--eval_steps="100" \
--logging_steps="50" \
--learning_rate="5e-4" \
--warmup_steps="3000" \
--model_name_or_path="facebook/wav2vec2-base" \
--fp16 \
--dataset_name="timit_asr" \
--train_split_name="train" \
--validation_split_name="test" \
--orthography="timit" \
--preprocessing_num_workers="$(nproc)" \
--group_by_length \
--freeze_feature_extractor \
--verbose_logging \
```
The resulting model and inference examples can be found [here](https://huggingface.co/elgeish/wav2vec2-base-timit-asr).
Some of the arguments above may look unfamiliar, let's break down what's going on:
`--orthography="timit"` applies certain text preprocessing rules, for tokenization and normalization, to clean up the dataset.
In this case, we use the following instance of `Orthography`:
```python
Orthography(
do_lower_case=True,
# break compounds like "quarter-century-old" and replace pauses "--"
translation_table=str.maketrans({"-": " "}),
)
```
The instance above is used as follows:
* creates a tokenizer with `do_lower_case=True` (ignores casing for input and lowercases output when decoding)
* replaces `"-"` with `" "` to break compounds like `"quarter-century-old"` and to clean up suspended hyphens
* cleans up consecutive whitespaces (replaces them with a single space: `" "`)
* removes characters not in vocabulary (lacking respective sound units)
`--verbose_logging` logs text preprocessing updates and when evaluating, using the validation split every `eval_steps`,
logs references and predictions.
### Fine-Tuning with Arabic Speech Corpus
Other datasets, like the [Arabic Speech Corpus dataset](https://huggingface.co/datasets/arabic_speech_corpus),
require more work! Let's take a look at the [script](./finetune_large_xlsr_53_arabic_speech_corpus.sh)
used to fine-tune [wav2vec2-large-xlsr-53](https://huggingface.co/elgeish/wav2vec2-large-xlsr-53-arabic):
```bash
#!/usr/bin/env bash
python run_asr.py \
--output_dir="./wav2vec2-large-xlsr-53-arabic-speech-corpus" \
--num_train_epochs="50" \
--per_device_train_batch_size="1" \
--per_device_eval_batch_size="1" \
--gradient_accumulation_steps="8" \
--eval_strategy="steps" \
--save_steps="500" \
--eval_steps="100" \
--logging_steps="50" \
--learning_rate="5e-4" \
--warmup_steps="3000" \
--model_name_or_path="elgeish/wav2vec2-large-xlsr-53-arabic" \
--fp16 \
--dataset_name="arabic_speech_corpus" \
--train_split_name="train" \
--validation_split_name="test" \
--max_duration_in_seconds="15" \
--orthography="buckwalter" \
--preprocessing_num_workers="$(nproc)" \
--group_by_length \
--freeze_feature_extractor \
--target_feature_extractor_sampling_rate \
--verbose_logging \
```
First, let's understand how this dataset represents Arabic text; it uses a format called
[Buckwalter transliteration](https://en.wikipedia.org/wiki/Buckwalter_transliteration).
We use the [lang-trans](https://github.com/kariminf/lang-trans) package to convert back to Arabic when logging.
The Buckwalter format only includes ASCII characters, some of which are non-alpha (e.g., `">"` maps to `"أ"`).
`--orthography="buckwalter"` applies certain text preprocessing rules, for tokenization and normalization, to clean up the dataset. In this case, we use the following instance of `Orthography`:
```python
Orthography(
vocab_file=pathlib.Path(__file__).parent.joinpath("vocab/buckwalter.json"),
word_delimiter_token="/", # "|" is Arabic letter alef with madda above
words_to_remove={"sil"}, # fixing "sil" in arabic_speech_corpus dataset
untransliterator=arabic.buckwalter.untransliterate,
translation_table=str.maketrans(translation_table = {
"-": " ", # sometimes used to represent pauses
"^": "v", # fixing "tha" in arabic_speech_corpus dataset
}),
)
```
The instance above is used as follows:
* creates a tokenizer with Buckwalter vocabulary and `word_delimiter_token="/"`
* replaces `"-"` with `" "` to clean up hyphens and fixes the orthography for `"ث"`
* removes words used as indicators (in this case, `"sil"` is used for silence)
* cleans up consecutive whitespaces (replaces them with a single space: `" "`)
* removes characters not in vocabulary (lacking respective sound units)
`--verbose_logging` logs text preprocessing updates and when evaluating, using the validation split every `eval_steps`,
logs references and predictions. Using the Buckwalter format, text is also logged in Arabic abjad.
`--target_feature_extractor_sampling_rate` resamples audio to target feature extractor's sampling rate (16kHz).
`--max_duration_in_seconds="15"` filters out examples whose audio is longer than the specified limit,
which helps with capping GPU memory usage.
### DeepSpeed Integration
To learn how to deploy Deepspeed Integration please refer to [this guide](https://huggingface.co/transformers/main/main_classes/deepspeed.html#deepspeed-trainer-integration).
But to get started quickly all you need is to install:
```bash
pip install deepspeed
```
and then use the default configuration files in this directory:
* `ds_config_wav2vec2_zero2.json`
* `ds_config_wav2vec2_zero3.json`
Here are examples of how you can use DeepSpeed:
(edit the value for `--num_gpus` to match the number of GPUs you have)
ZeRO-2:
```bash
PYTHONPATH=../../../src deepspeed --num_gpus 2 \
run_asr.py \
--output_dir=output_dir --num_train_epochs=2 --per_device_train_batch_size=2 \
--per_device_eval_batch_size=2 --eval_strategy=steps --save_steps=500 --eval_steps=100 \
--logging_steps=5 --learning_rate=5e-4 --warmup_steps=3000 \
--model_name_or_path=patrickvonplaten/wav2vec2_tiny_random_robust \
--dataset_name=hf-internal-testing/librispeech_asr_dummy --dataset_config_name=clean \
--train_split_name=validation --validation_split_name=validation --orthography=timit \
--preprocessing_num_workers=1 --group_by_length --freeze_feature_extractor --verbose_logging \
--deepspeed ds_config_wav2vec2_zero2.json
```
For ZeRO-2 with more than 1 gpu you need to use (which is already in the example configuration file):
```json
"zero_optimization": {
...
"find_unused_parameters": true,
...
}
```
ZeRO-3:
```bash
PYTHONPATH=../../../src deepspeed --num_gpus 2 \
run_asr.py \
--output_dir=output_dir --num_train_epochs=2 --per_device_train_batch_size=2 \
--per_device_eval_batch_size=2 --eval_strategy=steps --save_steps=500 --eval_steps=100 \
--logging_steps=5 --learning_rate=5e-4 --warmup_steps=3000 \
--model_name_or_path=patrickvonplaten/wav2vec2_tiny_random_robust \
--dataset_name=hf-internal-testing/librispeech_asr_dummy --dataset_config_name=clean \
--train_split_name=validation --validation_split_name=validation --orthography=timit \
--preprocessing_num_workers=1 --group_by_length --freeze_feature_extractor --verbose_logging \
--deepspeed ds_config_wav2vec2_zero3.json
```
### Pretraining Wav2Vec2
The `run_pretrain.py` script allows one to pretrain a Wav2Vec2 model from scratch using Wav2Vec2's contrastive loss objective (see official [paper](https://arxiv.org/abs/2006.11477) for more information).
It is recommended to pre-train Wav2Vec2 with Trainer + Deepspeed (please refer to [this guide](https://huggingface.co/transformers/main/main_classes/deepspeed.html#deepspeed-trainer-integration) for more information).
Here is an example of how you can use DeepSpeed ZeRO-2 to pretrain a small Wav2Vec2 model:
```bash
PYTHONPATH=../../../src deepspeed --num_gpus 4 run_pretrain.py \
--output_dir="./wav2vec2-base-libri-100h" \
--num_train_epochs="3" \
--per_device_train_batch_size="32" \
--per_device_eval_batch_size="32" \
--gradient_accumulation_steps="2" \
--save_total_limit="3" \
--save_steps="500" \
--logging_steps="10" \
--learning_rate="5e-4" \
--weight_decay="0.01" \
--warmup_steps="3000" \
--model_name_or_path="patrickvonplaten/wav2vec2-base-libri-100h" \
--dataset_name="librispeech_asr" \
--dataset_config_name="clean" \
--train_split_name="train.100" \
--preprocessing_num_workers="4" \
--max_duration_in_seconds="10.0" \
--group_by_length \
--verbose_logging \
--fp16 \
--deepspeed ds_config_wav2vec2_zero2.json \
```
