SciFact dataset - minor changes

Hi,

SciFact dataset creator here. First of all, thanks for adding the dataset to Huggingface, much appreciated!

I'd like to make a few minor changes, including the citation information and the `_URL` from which to download the dataset. Can I submit a PR for this?

It also looks like the dataset is being downloaded directly from Huggingface's Google cloud account rather than via the `_URL` in [scifact.py](https://github.com/huggingface/datasets/blob/master/datasets/scifact/scifact.py). Can you help me update the version on gcloud?

Thanks,

Dave

Hi Dave,
You are more than welcome to open a PR to make these changes! 🤗
You will find the relevant information about opening a PR in the [contributing guide](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md) and in the [dataset addition guide](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md).

Pinging also @lhoestq for the Google cloud matter.

Sure ! Also feel free to ping us for reviews or if we can help :)

What makes you think that ?
Afaik there's no scifact on our google storage

OK! We're organizing a [shared task](https://sdproc.org/2021/sharedtasks.html#sciver) based on the dataset, and I made some updates and changed the download URL - so the current code points to a dead URL. I'll update appropriately once the task is finalized and make a PR.

You're right, I had the data cached on my machine somewhere. 



I opened a PR about this: https://github.com/huggingface/datasets/pull/1780. Closing this issue, will continue there.
Adding adversarialQA dataset

Adding the adversarialQA dataset (https://adversarialqa.github.io/) from Beat the AI (https://arxiv.org/abs/2002.00293)

Oh that's a really cool one, we'll review/merge it soon!

In the meantime, do you have any specific positive/negative feedback on the process of adding a datasets Max?
Did you follow the instruction in the [detailed step-by-step](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md)?

Thanks Thom, been a while, hope all is well!

Yes, I followed the step by step instructions and found them pretty straightforward. The only things I wasn't sure of were what should go into the YAML tags field for the dataset card, and whether there was a list of options somewhere (maybe akin to the metrics?) of the possible supported tasks. I found the rest very intuitive and the automated metadata and dummy data generation very handy. Thanks!

Good point! pinging @yjernite here so he can improve this part!

@maxbartolo cool addition!

For the YAML tag, you should use the tagging app we provide to choose from a drop-down menu:
https://github.com/huggingface/datasets-tagging

The process is described toward the end of the [step-by-step guide](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md#tag-the-dataset-and-write-the-dataset-card), do you have any suggestions for making it easier to find?

Otherwise, the dataset card is really cool, thanks for making it so complete!


@yjernite

Thanks, YAML tags added. I think my main issue was with the flow of the [step-by-step guide](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md). For example, the [card creator](https://huggingface.co/datasets/card-creator/) is introduced in Step 4, right after creating an empty directory for your dataset. The first field it requires are the YAML tags, which (at least for me) was the last step of the process.

I'd suggest having the guide structured in the same order as the creation process. For me it was something like:
- Step 1: Preparing your env
- Step 2: Write the loading/processing code
- Step 3: Automatically generate dummy data and `dataset_infos.json`
- Step 4: Tag the dataset
- Step 5: Write the dataset card using the [card creator](https://huggingface.co/datasets/card-creator/)
- Step 6: Open a Pull Request on the main HuggingFace repo and share your work!!

Thanks again!
Installation using conda

Will a conda package for installing datasets be added to the huggingface conda channel? I have installed transformers using conda and would like to use the datasets library to use some of the scripts in the transformers/examples folder but am unable to do so at the moment as datasets can only be installed using pip and using pip in a conda environment is generally a bad idea in my experience.

Yes indeed the idea is to have the next release on conda cc @LysandreJik 

Great! Did you guys have a timeframe in mind for the next release?

Thank you for all the great work in developing this library.

I think we can have `datasets` on conda by next week. Will see what I can do!

Thank you. Looking forward to it.

`datasets` has been added to the huggingface channel thanks to @LysandreJik :)
It depends on conda-forge though

```
conda install -c huggingface -c conda-forge datasets
```
Silicone

My collaborators and I within the Affective Computing team at Telecom Paris would like to push our spoken dialogue dataset for publication.

When should we expect to see our dataset appear in the search dropdown at huggingface.co?

Hi @eusip,

> When should we expect to see our dataset appear in the search dropdown at huggingface.co?

when this PR is merged.

Thanks!

I've implemented all the changes requested by @lhoestq but I made the mistake of trying to change the remote branch name. 

Hopefully the changes are seen on your end as both branches `silicone` and `main` should be up-to-date.

It looks like the PR includes changes about many other files than the ones for Silicone (+30,000 line changes)

Maybe you can try to create another branch and another PR ?

Sure. I will make a new pull request.
Added generated READMEs for datasets that were missing one.

This is it: we worked on a generator with Yacine @yjernite , and we generated dataset cards for all missing ones (161), with all the information we could gather from datasets repository, and using dummy_data to generate examples when possible.

Code is available here for the moment: https://github.com/madlag/datasets_readme_generator .
We will move it to a Hugging Face repository and to https://huggingface.co/datasets/card-creator/ later.


Looks like we need to trim the ones with too many configs, will look into it tomorrow!
Some datasets miss dataset_infos.json or dummy_data.zip

While working on dataset REAME generation script at https://github.com/madlag/datasets_readme_generator , I noticed that some datasets miss a dataset_infos.json : 

```
c4
lm1b
reclor
wikihow
```

And some does not have a dummy_data.zip : 

```
kor_nli
math_dataset
mlqa
ms_marco
newsgroup
qa4mre
qangaroo
reddit_tifu
super_glue
trivia_qa
web_of_science
wmt14
wmt15
wmt16
wmt17
wmt18
wmt19
xtreme
```

But it seems that some of those last do have a "dummy" directory .



Thanks for reporting.
We should indeed add all the missing dummy_data.zip and also the dataset_infos.json at least for lm1b, reclor and wikihow.

For c4 I haven't tested the script and I think we'll require some optimizations regarding beam datasets before processing it.


Closing since the dummy data generation is deprecated now (and the issue with missing metadata seems to be addressed).
fix ner_tag bugs in thainer

fix bug that results in `ner_tag` always equal to 'O'.

> Thanks :)
> 
> Apparently the dummy_data.zip got removed. Is this expected ?
> Also can you remove the `data-pos.conll` file that you added ?

Not expected. I forgot to remove the `dummy_data` folder used to create `dummy_data.zip`. 
Changed to only `dummy_data.zip`.
Question: Shouldn't .info be a part of DatasetDict?

Currently, only `Dataset` contains the .info or .features, but as many datasets contains standard splits (train, test) and thus the underlying information is the same (or at least should be) across the datasets. 

For instance:
```
>>> ds = datasets.load_dataset("conll2002", "es")
>>> ds.info
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'DatasetDict' object has no attribute 'info'
```

I could imagine that this wouldn't work for datasets dicts which hold entirely different datasets (multimodal datasets), but it seems odd that splits of the same dataset is treated the same as what is essentially different datasets. 

Intuitively it would also make sense that if a dataset is supplied via. the load_dataset that is have a common .info which covers the entire dataset.

It is entirely possible that I am missing another perspective

We could do something. There is a part of `.info` which is split specific (cache files, split instructions) but maybe if could be made to work.

Yes this was kinda the idea I was going for. DatasetDict.info would be the shared info amongs the datasets (maybe even some info on how they differ).
Dataset Error: DaNE contains empty samples at the end

The dataset DaNE, contains empty samples at the end. It is naturally easy to remove using a filter but should probably not be there, to begin with as it can cause errors.

```python
>>> import datasets
[...]
>>> dataset = datasets.load_dataset("dane")
[...]
>>> dataset["test"][-1]
{'dep_ids': [], 'dep_labels': [], 'lemmas': [], 'morph_tags': [], 'ner_tags': [], 'pos_tags': [], 'sent_id': '', 'text': '', 'tok_ids': [], 'tokens': []}
>>> dataset["train"][-1]
{'dep_ids': [], 'dep_labels': [], 'lemmas': [], 'morph_tags': [], 'ner_tags': [], 'pos_tags': [], 'sent_id': '', 'text': '', 'tok_ids': [], 'tokens': []}
```

Best,
Kenneth

Thanks for reporting, I opened a PR to fix that

One the PR is merged the fix will be available in the next release of `datasets`.

If you don't want to wait the next release you can still load the script from the master branch with

```python
load_dataset("dane", script_version="master")
```

If you have other questions feel free to reopen :)
Update README.md of covid-tweets-japanese

Update README.md of covid-tweets-japanese added by PR https://github.com/huggingface/datasets/pull/1367 and https://github.com/huggingface/datasets/pull/1402.

- Update "Data Splits" to be more precise that no information is provided for now.
  - old: [More Information Needed]
  - new: No information about data splits is provided for now.

- The automatic generation of links seemed not working properly, so I added a space before and after the URL to make the links work correctly.

Thanks for reviewing and merging!

cc100 was added recently, that's why it wasn't available yet.

To load it you can just update `datasets`
```
pip install --upgrade datasets
```

```python
from datasets import load_dataset

lang = "en"
dataset = load_dataset("cc100", lang=lang, split="train")
```
Switchboard Dialog Act Corpus added under `datasets/swda`

Switchboard Dialog Act Corpus

Intro:
The Switchboard Dialog Act Corpus (SwDA) extends the Switchboard-1 Telephone Speech Corpus, Release 2,
with turn/utterance-level dialog-act tags. The tags summarize syntactic, semantic, and pragmatic information
about the associated turn. The SwDA project was undertaken at UC Boulder in the late 1990s.

Details:
[homepage](http://compprag.christopherpotts.net/swda.html)
[repo](https://github.com/NathanDuran/Switchboard-Corpus/raw/master/swda_data/)

I believe this is an important dataset to have since there is no dataset related to dialogue act added.

I didn't find any formatting for pull request. I hope all this information is enough.

For any support please contact me. 

@lhoestq Thank you for your detailed comments! I fixed everything you suggested.

Please let me know if I'm missing anything else.

It looks like the Transcript and Utterance objects are missing, maybe we can mention it in the README ? Or just add them ? @gmihaila @bhavitvyamalik 

Hi @lhoestq,
I'm working on this to add the full dataset

> It looks like the Transcript and Utterance objects are missing, maybe we can mention it in the README ? Or just add them ? @gmihaila @bhavitvyamalik

@lhoestq  Any info on how to add them?

@gmihaila, instead of using the current repo you should look into [this](https://github.com/cgpotts/swda). You can use the `csv` files uploaded in this repo (`swda.zip`) to access other fields and include them in this dataset. It has one dependency too, `swda.py`, you can download that separately and include it in your dataset's folder to be imported while reading the `csv` files.

Almost all the attributes of `Transcript` and `Utterance` objects are of the type str, int, or list. As far as `trees` attribute is concerned in utterance object you can simply parse it as string and user can maybe later convert it to nltk.tree object

@bhavitvyamalik Thank you for the clarification! 

I didn't use [that](https://github.com/cgpotts/swda) because it doesn't have the splits. I think in combination with [what I used](https://github.com/NathanDuran/Switchboard-Corpus) would help.

Let me know if I can help! I can make those changes if you don't have the time.

I'm a bit busy for the next 2 weeks. I'll be able to complete it by end of January only. Maybe you can start with it and I'll help you?
Also, I looked into the official train/val/test splits and not all the files are there in the repo I used so I think either we'll have to skip them or put all of that into just train

Yes, I can start working on it and ask you to do a code review.

Yes, not all files are there. I'll try to find papers that have the correct and full splits, if not, I'll do like you suggested.

Thank you again for your help @bhavitvyamalik !

new version of Ted Talks IWSLT (WIT3)

In the previous iteration #1608 I had used language pairs. Which created 21,582 configs (109*108) !!! 

Now, TED talks in _each language_ is a separate config. So it's more cleaner with _just 109 configs_  (one for each language). Dummy files were created manually. 

Locally  I was able to clear the `python datasets-cli test datasets/......` . Which created the `dataset_info.json`  file . The test for the dummy files was also cleared. However couldn't figure out how to specify the local data folder for the real dataset


**Note: that this requires manual download of the dataset.** 
**Note2: The high number of _Files changed (112)_ is because of the large number of dummy files/configs!**

> Nice thank you ! Actually as it is a translation dataset we should probably have one configuration = one language pair no ?
> 
> Could you use the same trick for this dataset ?

I was looking for this input, infact I had written a long post on the Slack channel,...(_but unfortunately due to the holidays didn;t get a respones_). Initially I had tried with language pairs and then with specific language configs. 

I'll have a look at the `opus-gnomes` dataset


Oh sorry I must have missed your message then :/
I was off a few days during the holidays

Hopefully this trick can enable the use of any language pair (+ year ?) combination and also simplify a lot the dummy data creation since it will only require a few configs.

Updated it as per the comments. But couldn't figure out why the dummy tests are failing >>

Unable to Download Hindi Wikipedia Dataset

I used the Dataset Library in Python to load the wikipedia dataset with the Hindi Config 20200501.hi along with something called beam_runner='DirectRunner' and it keeps giving me the error that the file is not found. I have attached the screenshot of the error and the code both. Please help me to understand how to resolve this issue.

Currently this dataset is only available when the library is installed from source since it was added after the last release.

We pin the dataset version with the library version so that people can have a reproducible dataset and processing when pinning the library.

We'll see if we can provide access to newer datasets with a warning that they are newer than your library version, that would help in cases like yours.

So for now, should i try and install the library from source and then try out the same piece of code? Will it work then, considering both the versions will match then?

Yes

Hey, so i tried installing the library from source using the commands : **git clone https://github.com/huggingface/datasets**,  **cd datasets** and then **pip3 install -e .**. But i still am facing the same error that file is not found. Please advise.

The Datasets library version now is 1.1.3 by installing from source as compared to the earlier 1.0.3 that i had loaded using pip command but I am still getting same error

![Error](https://user-images.githubusercontent.com/30871963/103479005-69f3b080-4df0-11eb-83ae-58d7bb56a90e.png)


Looks like the wikipedia dump for hindi at the date of 05/05/2020 is not available anymore.
You can try to load a more recent version of wikipedia
```python
from datasets import load_dataset

d = load_dataset("wikipedia", language="hi", date="20210101", split="train", beam_runner="DirectRunner")
```

Okay, thank you so much
wiki_dpr pre-processing performance

I've been working with wiki_dpr and noticed that the dataset processing is seriously impaired in performance [1]. It takes about 12h to process the entire dataset. Most of this time is simply loading and processing the data, but the actual indexing is also quite slow (3h).

I won't repeat the concerns around multiprocessing as they are addressed in other issues (#786), but this is the first obvious thing to do. Using cython to speed up the text manipulation may be also help. Loading and processing a dataset of this size in under 15 minutes does not seem unreasonable on a modern multi-core machine. I have hit such targets myself on similar tasks. Would love to see this improve.

The other issue is that it takes 3h to construct the FAISS index. If only we could use GPUs with HNSW, but we can't. My sharded GPU indexing code can build an IVF + PQ index in 10 minutes on 20 million vectors. Still, 3h seems slow even for the CPU.

It looks like HF is adding only 1000 vectors at a time by default [2], whereas the faiss benchmarks adds 1 million vectors at a time (effectively) [3]. It's possible the runtime could be reduced with a larger batch. Also, it looks like project dependencies ultimately use OpenBLAS, but this is known to have issues when combined with OpenMP, which HNSW does [3]. A workaround is to set the environment variable `OMP_WAIT_POLICY=PASSIVE` via `os.environ` or similar.

Hi ! And thanks for the tips :) 

Indeed currently `wiki_dpr` takes some time to be processed.
Multiprocessing for dataset generation is definitely going to speed up things.

Regarding the index note that for the default configurations, the index is downloaded instead of being built, which avoid spending time on constructing the index. However in other cases it would be awesome to make the construction faster.

Any contribution that can help things faster are welcome. In particular in you have some code that can build a wiki_dpr IVF PQ index in a sharded GPU setup and would like to share it, we can add it to an `examples` folder. In particular since faiss is becoming the library of reference for dataset indexing for tasks like Open Domain Question Answering.



I'd be happy to contribute something when I get the time, probably adding multiprocessing and / or cython support to wiki_dpr. I've written cythonized apache beam code before as well.

For sharded index building, I used the FAISS example code for indexing 1 billion vectors as a start. I'm sure you're aware that the documentation isn't great, but the source code is fairly easy to follow.

Nice thanks ! That would be awesome to make its construction faster :)

update saving and loading methods for faiss index so to accept path l…

- Update saving and loading methods for faiss index so to accept path like objects from pathlib

The current code only supports using a string type to save and load a faiss index. This change makes it possible to use a string type OR a Path from [pathlib](https://docs.python.org/3/library/pathlib.html). The codes becomes a more intuitive this way I think.

Seems ok for me, what do you think @lhoestq ?
Arrow file is too large when saving vector data

I computed the sentence embedding of each sentence of bookcorpus data using bert base and saved them to disk. I used 20M sentences and the obtained arrow file is about 59GB while the original text file is only about 1.3GB. Are there any ways to reduce the size of the arrow file?

Hi !
The arrow file size is due to the embeddings. Indeed if they're stored as float32 then the total size of the embeddings is

20 000 000 vectors * 768 dimensions * 4 bytes per dimension ~= 60GB

If you want to reduce the size you can consider using quantization for example, or maybe using dimension reduction techniques.


Thanks for your reply @lhoestq.
I want to save original embedding for these sentences for subsequent calculations. So does arrow have a way to save in a compressed format to reduce the size of the file?

Arrow doesn't have compression since it is designed to have no serialization overhead

I see. Thank you.

    FileNotFoundError: Couldn't find file locally at narrativeqa/narrativeqa.py, or remotely at 
        https://raw.githubusercontent.com/huggingface/datasets/1.1.3/datasets/narrativeqa/narrativeqa.py or 
        https://s3.amazonaws.com/datasets.huggingface.co/datasets/datasets/narrativeqa/narrativeqa.py

Workaround: manually copy the `narrativeqa.py` builder into my local directory with 

    curl https://raw.githubusercontent.com/huggingface/datasets/master/datasets/narrativeqa/narrativeqa.py -o narrativeqa.py

and load the dataset as `load_dataset('narrativeqa.py')` everything works fine. I'm on datasets v1.1.3 using Python 3.6.10.

Hi @eric-mitchell,
I think the issue might be that this dataset was added during the community sprint and has not been released yet. It will be available with the v2 of `datasets`.
For now, you should be able to load the datasets after installing the latest (master) version of `datasets` using pip:
`pip install git+https://github.com/huggingface/datasets.git@master`

@bhavitvyamalik Great, thanks for this! Confirmed that the problem is resolved on master at [cbbda53](https://github.com/huggingface/datasets/commit/cbbda53ac1520b01f0f67ed6017003936c41ec59).

Update: HuggingFace did an intermediate release yesterday just before the v2.0.

To load it you can just update `datasets`

`pip install --upgrade datasets`
HoVeR dataset fails to load

Hi! I'm getting an error when trying to load **HoVeR** dataset. Another one (**SQuAD**) does work for me. I'm using the latest (1.1.3) version of the library.

```

Hover was added recently, that's why it wasn't available yet.

To load it you can just update `datasets`
```
pip install --upgrade datasets
```

and then you can load `hover` with

```python
from datasets import load_dataset

dataset = load_dataset("hover")
```

bug with sst2 in glue 

Hi
I am getting very low accuracy on SST2 I investigate this and observe that for this dataset sentences are tokenized, while this is correct for the other datasets in GLUE, please see below.
Is there any alternatives I could get untokenized sentences? I am unfortunately under time pressure to report some results on this dataset. thank you for your help. @lhoestq 
 
```
>>> a =  datasets.load_dataset('glue', 'sst2', split="validation", script_version="master")

Maybe you can use nltk's treebank detokenizer ?
```python
from nltk.tokenize.treebank import TreebankWordDetokenizer

TreebankWordDetokenizer().detokenize("it 's a charming and often affecting journey . ".split())
# "it's a charming and often affecting journey."
```

I am looking for alternative file URL here instead of adding extra processing code: https://github.com/huggingface/datasets/blob/171f2bba9dd8b92006b13cf076a5bf31d67d3e69/datasets/glue/glue.py#L174

I don't know if there exists a detokenized version somewhere. Even the version on kaggle is tokenized
Added `pn_summary` dataset

#1635 

You did a great job with the fluent procedure regarding adding a dataset. I took the chance to add the dataset on my own. Thank you for your awesome job, and I hope this dataset found the researchers happy, specifically those interested in Persian Language (Farsi)!

As always, I got stuck in the correct order of imports 😅
@lhoestq, It's finished!

@lhoestq, It's done! Is there anything else that needs changes?
Persian Abstractive/Extractive Text Summarization

Assembling datasets tailored to different tasks and languages is a precious target. This would be great to have this dataset included.

## Adding a Dataset
- **Name:** *pn-summary*
- **Description:** *A well-structured summarization dataset for the Persian language consists of 93,207 records. It is prepared for Abstractive/Extractive tasks (like cnn_dailymail for English). It can also be used in other scopes like Text Generation, Title Generation, and News Category Classification.*
- **Paper:** *https://arxiv.org/abs/2012.11204*
- **Data:** *https://github.com/hooshvare/pn-summary/#download*
- **Motivation:** *It is the first Persian abstractive/extractive Text summarization dataset (like cnn_dailymail for English)!*

Inspecting datasets per category

Hi
Is there a way I could get all NLI datasets/all QA datasets to get some understanding of available datasets per category? this is hard for me to inspect the datasets one by one in the webpage, thanks for the suggestions @lhoestq 

That's interesting, can you tell me what you think would be useful to access to inspect a dataset?

You can filter them in the hub with the search by the way: https://huggingface.co/datasets have you seen it?

Hi @thomwolf 
thank you, I was not aware of this, I was looking into the data viewer linked into readme page. 

This is exactly what I was looking for, but  this does not work currently, please see the attached 
I am selecting to see all nli datasets in english and it retrieves none. thanks

I see 4 results for NLI in English but indeed some are not tagged yet and missing (GLUE), we will focus on that in January (cc @yjernite): https://huggingface.co/datasets?filter=task_ids:natural-language-inference,languages:en

Hi! You can use `huggingface_hub`'s `list_datasets` for that now:
```python
import huggingface_hub # pip install huggingface_hub
huggingface_hub.list_datasets(filter="task_categories:question-answering")
# or
huggingface_hub.list_datasets(filter=("task_categories:natural-language-inference", "languages:"en"))

social_i_qa wrong format of labels

Hi,
there is extra "\n" in labels of social_i_qa datasets, no big deal, but I was wondering if you could remove it to make it consistent.
so label is 'label': '1\n', not '1'
thanks

Thank you

Adding a link to the guide on adding a dataset if someone want to give it a try: https://github.com/huggingface/datasets#add-a-new-dataset-to-the-hub

we should add this guide to the issue template @lhoestq 

thanks @thomwolf , this is added now. The template is correct, sorry my mistake not to include it.

`Dataset.map` disable progress bar

I can't find anything to turn off the `tqdm` progress bars while running a preprocessing function using `Dataset.map`. I want to do akin to `disable_tqdm=True` in the case of `transformers`. Is there something like that?

Progress bar can be disabled like this:
```python
from datasets.utils.logging import set_verbosity_error
set_verbosity_error()
```

There is this line in `Dataset.map`:
```python
not_verbose = bool(logger.getEffectiveLevel() > WARNING)
```

So any logging level higher than `WARNING` turns off the progress bar.

From the linked issues above, an up-to-date solution is:

```python
from datasets.utils.logging import disable_progress_bar
disable_progress_bar()
```

https://github.com/huggingface/datasets/blob/c6e08fcfc3a04e53430c26fa7c07da4cb18d977d/src/datasets/utils/logging.py#L233-L236

Why not have a parameter in the function such as `progress: bool = True`?

+1. We shouldn't need to play with logging levels for a simple thing like this. For instance, trainers have an option `show_progress` that does exactly this.

Bump on this, such a simple QOL issue why can't we fix this?
Add CLIMATE-FEVER dataset

As suggested by @SBrandeis , fresh PR that adds CLIMATE-FEVER. Replaces PR #1579.

---

A dataset adopting the FEVER methodology that consists of 1,535 real-world claims regarding climate-change collected on the internet. Each claim is accompanied by five manually annotated evidence sentences retrieved from the English Wikipedia that support, refute or do not give enough information to validate the claim totalling in 7,675 claim-evidence pairs. The dataset features challenging claims that relate multiple facets and disputed cases of claims where both supporting and refuting evidence are present.

More information can be found at:

* Homepage: http://climatefever.ai
* Paper: https://arxiv.org/abs/2012.00614

Thank you @lhoestq for your comments! 😄 I added your suggested changes, ran the tests and regenerated `dataset_infos.json` and `dummy_data`.
Can't call shape on the output of select()

I get the error `TypeError: tuple expected at most 1 argument, got 2` when calling `shape` on the output of `select()`.
It's line 531 in shape in arrow_dataset.py that causes the problem:
``return tuple(self._indices.num_rows, self._data.num_columns)``
This makes sense, since `tuple(num1, num2)` is not a valid call.
 
Full code to reproduce:

```python
dataset = load_dataset("cnn_dailymail", "3.0.0")
train_set = dataset["train"]
t = train_set.select(range(10))
print(t.shape)

Indeed that's a typo, do you want to open a PR to fix it?

Yes, created a PR
Adding myPOS2017 dataset

myPOS Corpus (Myanmar Part-of-Speech Corpus) for Myanmar language NLP Research and Developments

I've updated the code and Readme to reflect your comments.
Thank you very much,

looks like this PR includes changes about many other files than the ones for myPOS2017

Could you open another branch and another PR please ?
(or fix this branch)

Hi @hungluumfc ! Have you had a chance to fix this PR so that it only includes the changes for `mypos` ? 

Feel free to ping me if you have questions or if I can help :) 

Thanks for your contribution, @hungluumfc. Are you still interested in adding this dataset?

We are removing the dataset scripts from this GitHub repo and moving them to the Hugging Face Hub: https://huggingface.co/datasets

We would suggest you create this dataset there. Please, feel free to tell us if you need some help.
data loader for reading comprehension task

added doc2dial data loader and dummy data for reading comprehension task.

Thank you for all the feedback! I have updated the dummy data with a zip under 30KB, which needs to include at least one data instance from both document domain and dialog domain. Please let me know if it is still too big. Thanks!

Thank you again for the feedback! I am not too sure what the preferable style for data instance in readme, but still added my edits. Thanks!
Can't filter language:EN on https://huggingface.co/datasets

When visiting https://huggingface.co/datasets, I don't see an obvious way to filter only English datasets. This is unexpected for me, am I missing something? I'd expect English to be selectable in the language widget. This problem reproduced on Mozilla Firefox and MS Edge:

cc'ing @mapmeld 

Full language list is now deployed to https://huggingface.co/datasets ! Recommend close

Cool @mapmeld ! My 2 cents (for a next iteration), it would be cool to have a small search widget in the filter dropdown as you have a ton of languages now here! Closing this in the meantime.
