Title: Close parquet writer properly in `push_to_hub`
State: closed

We don’t call writer.close(), which causes https://github.com/huggingface/datasets/issues/4077. It can happen that we upload the file before the writer is garbage collected and writes the footer.

I fixed this by explicitly closing the parquet writer.

I am facing the same scenario. Let me explain the situation point. I have a glue ETL job

1--> My files are in parquet format and stored in AWS s3.
2--> I am iterating a  loop for a data set where the same file name can occur with diffrent other data.
3--> I read the parquet and saved it in a pandas data frame.
4--> Done some operation on that data frame
5--> upload the updated data frame into the S3 parquet file.  Below are code snippet what I am using to save the updated 
         data frame into parquet format and load into S3
         `header_name_column_list = dict(data_frame)
          header_list = []
            for col_id, col_type in header_name_column_list.items():
                header_list.append(pyarrow.field(col_id, pyarrow.string()))
            table_schema = pyarrow.schema(header_list)
            table = pyarrow.Table.from_pandas(data_frame, schema=table_schema, preserve_index=False)
            writer = parquet.ParquetWriter(b_buffer, table.schema)
            writer.write_table(table)
            writer.close()
            b_buffer.seek(0)
            .....
            ....
           self.s3_client.upload_fileobj(
                b_buffer,
                self.bucket,
                file_key,
                ExtraArgs=extra_args)`

But when I executed the glue etl job, the first time it works properly and but in the next iteration, when I try to open the same file got that error.

Title: ArrowInvalid: Parquet magic bytes not found in footer. Either the file is corrupted or this is not a parquet file.
State: closed
Labels: description: Something isn't working
name: bug

## Describe the bug

When uploading a relatively large image dataset of > 1GB, reloading doesn't work for me, even though pushing to the hub went just fine.

Basically, I do:

```
from datasets import load_dataset

dataset = load_dataset("imagefolder", data_files="path_to_my_files")

dataset.push_to_hub("dataset_name") # works fine, no errors

reloaded_dataset = load_dataset("dataset_name")
```

and it returns:

```
/usr/local/lib/python3.7/dist-packages/pyarrow/error.pxi in pyarrow.lib.check_status()

ArrowInvalid: Parquet magic bytes not found in footer. Either the file is corrupted or this is not a parquet file.
```

I created a Colab notebook to reproduce my error: https://colab.research.google.com/drive/141LJCcM2XyqprPY83nIQ-Zk3BbxWeahq?usp=sharing

Add ROUGE metric card.

I've left the 'Values from popular papers' section empty for the time being because I don't know the summarization literature very well and am therefore not sure which paper(s) to pull from (note that the original rouge paper does not seem to present specific values, just correlations with human judgements). Any suggestions on which paper(s) to pull from would be helpful! :)

## Adding a Dataset
- **Name:** CCAgT dataset: Images of Cervical Cells with AgNOR Stain Technique
- **Description:** The dataset contains 2540 images (1600x1200 where each pixel is 0.111μm×0.111μm) from three different slides, having at least one nucleus per image. These images are from fields belonging to a sample cervical slide, colored with silver-stained, a method known as Argyrophilic Nucleolar Organizer Regions (AgNOR).
- **Paper:** https://doi.org/10.1109/cbms49503.2020.00110
- **Data:** https://arquivos.ufsc.br/d/373be2177a33426a9e6c/ or https://drive.google.com/drive/u/4/folders/1TBpYCv6S1ydASLauSzcsvO7Wc5O-WUw0
- **Motivation:** This is a unique dataset (because of the stain), for a major health problem, cervical cancer, with real data.

Instructions to add a new dataset can be found [here](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md).

Hi, this is a public version of the dataset that I have been working on, soon we will have another version of this dataset. But until this new version goes out, I thought I would add this dataset here, if it makes sense for the repository. You can assign the task to me if possible 

Comments:
Awesome ! Let us know if you have questions or if we can help ;) I'm assigning you

PS: if possible, please try to not use Google Drive links in your dataset script, since Google Drive has download quotas and is not always reliable.

HI, I was waiting to come out in the second version to do the implementation.

Not a big deal but Hungarian is considered an Eastern European language, together with Serbian, Slovak, Slovenian (all correctly categorized; Slovenia is mostly to the West of Hungary, by the way).


Comments:
Hi @wranai, thanks for reporting.

Please note that the information about language families and groups is taken form the original paper: [XTREME-S: Evaluating Cross-lingual Speech Representations](https://arxiv.org/abs/2203.10752).

If that information is wrong, feel free to contact the paper's authors to suggest that correction.

Comments:
Hi @Jun-jie-Huang,

As the error message says, ".pkl" data files are not supported.

If you would like to share your dataset on the Hub, you would need:
- either to create a Python loading script, that loads the data in any format
- or to transform your data files to one of the supported formats (listed in the error message above: CSV, JSON, Parquet, TXT,...)

You can find the details in our docs:

Title: Improve out of bounds error message
State: closed

In 1.18.4 with https://github.com/huggingface/datasets/pull/3719 we introduced an error message for users using `select` with out of bounds indices. The message ended up being confusing for some users because it mentioned negative indices, which is not the main use case.

I replaced it with a message that is very similar to the one you get with you try to access a list with an out-of-range index.

Following https://github.com/huggingface/datasets/pull/4066 we need to update many dataset tags to use the new ones. This PR takes case of this and is quite big - feel free to review only certain tags if you don't want to spend too much time on it.

Note that the CI will never be green for this PR, because many dataset cards have missing tags or sections, and fixing them is out of scope of this PR (the CI on master will be green anyway)

Looks good, but I think we are missing some scripts with outdated tags (RedCaps, MNIST, ...).

Just updated the tags of vision datasets :)
We can figure out one for image datasets without labels like PASS - not sure how to name the task for this, maybe `image-fill-mask` (for consistency with language modeling for pretraining) / `masked-auto-encoding` (from ViT). Let's see that in another PR later

Comments:
Hi @Arij-Aladel, thanks for reporting.

This issue was already reported 
- #3784

and its root cause is a change in the Google Drive service. See:
- #3786 

We have already fixed it in our 2.0.0 release. See:
- #3787 

Please, update your `datasets` version:
```
pip install -U datasets
```
and retry loading the dataset by forcing its redownload:
```python
dataset = load_dataset("cnn_dailymail", "3.0.0", download_mode="force_redownload")
```
Title: Deprecate canonical Multilingual Librispeech
State: closed

Deprecate canonical Multilingual Librispeech in favor of [the community one](https://huggingface.co/datasets/facebook/multilingual_librispeech) which supports streaming.

However, there is a problem regarding new ASR template schema: since it's changed, I guess all community datasets that use this template do not work with new version of the library, including MLS. Should we somehow notify users about that or is it possible to change this line ourselves? For MLS specifically, I cannot change the code directly as I'm not the member of the Facebook org. 

Hm, and the code should be change after the release, no?

Comments:
_The documentation is not available anymore as the PR was closed or merged._

Yes, as discussed in #4006 we should update facebook/multilingual_librispeech indeed before we do a release. @anton-l could you help taking care of updating facebook/multilingual_librispeech ? We need to update the task template
```python
task_templates=[AutomaticSpeechRecognition(audio_column="audio", transcription_column="text")],
```
and write that `datasets>=2.1` is necessary to load it in the dataset card.

Once the change is done we can merge this PR and do the release I think

@polinaeterna @lhoestq 
Updated the script and the dataset card: https://huggingface.co/datasets/facebook/multilingual_librispeech 

@anton-l @lhoestq now previewer doesn't work for this datasets as it cannot recognize new `audio_column` argument:
![image](https://user-images.githubusercontent.com/16348744/161233533-3170760b-5141-4525-9592-6675669c223a.png)

I'm not an expert in previewer things, where should I look into the corresponding code?

Yes, there are several datasets with the same error, eg https://github.com/huggingface/datasets-preview-backend/issues/188. I'm not sure what I should do to fix this? Upgrade datasets to master?


@anton-l ended up removing the task template in facebook/multilingual_librispeech to make it work for the current version of `datasets` and fix the viewer :) thanks !

@lhoestq can we merge now? ^^
Title: Updated annotations for nli_tr dataset

This PR adds annotation tags for `nli_tr` dataset so that the dataset can be searchable wrt. relevant query parameters.

The annotations in this PR are based on the existing annotations of `snli` and `multi_nli` datasets as `nli_tr` is a machine-generated extension of those datasets.

This PR is intended only for updating the annotation labels but a followup PR will focus on updating the missing sections in the `README.md` as well.

Title: Unexpected behavior of _TempDirWithCustomCleanup
State: open
Labels: description: Something isn't working
name: bug

## Describe the bug
This is not 100% a bug in `datasets`, but behavior that surprised me and I think this could be made more robust on the `datasets`side. 

When using `datasets.disable_caching()`, cache files are written to a temporary directory. This directory should be based on the environment variable TMPDIR. I want to set TMPDIR at runtime using os.ENVIRON["TMPDIR"] = something, but depending on other imported modules this can fail to take effect. 

## Steps to reproduce the bug
`_TempDirWithCustomCleanup` relies on `tempfile` to generate a path to a temporary directory. However, `tempfile` generates the path only once. This can be a problem when trying to set TMPDIR at runtime whenever other code imports `tempfile` first and does something unexpected. 

For example (after too much trial and error) I found out that a different part of the code base I work with defines a class `PatchedDataCollatorForLanguageModeling(transformers.DataCollatorForLanguageModeling)` based on a `transformers` class.  This import is enough to trigger `tempfile` to generate `tempfile` to generate a temporary path and leading to the wrong path being cached in `tempfile.tempdir`.

## Suggestion:
I could file this also as bug with `transformers`, but I think fixing this on the datasets would be much more robust:
Datasets could recompute the temporary path once (technically possible via `tempfile._get_default_tempdir` or resetting 
 the global variable `tempfile.tmpdir` to None) before setting its own global  `_TEMP_DIR_FOR_TEMP_CACHE_FILES`.




Comments:
Hi ! Would setting TMPDIR at the beginning of your python script/session work ? I mean, even before importing transformers, datasets, etc. and using them ? I think this would be the most robust solution given any library that uses `tempfile`. I don't think we aim to support environment variables to be changed at run time

Hi, yeah setting the environment variable before the imports / as environment variable outside is another way to fix this. I am just arguing that `datasets` already uses its own global variable to track temporary files: `_TEMP_DIR_FOR_TEMP_CACHE_FILES`, and the creation of this global variable should respect TMPDIR instead of relying on tempfile to do so.
Title: Modify datatype from `int32` to `float` for pearsonr, spearmanr.
State: closed
Labels: description: New feature or request
name: enhancement

**Is your feature request related to a problem? Please describe.**
- Now [Pearsonr](https://github.com/huggingface/datasets/blob/master/metrics/pearsonr/pearsonr.py) and [Spearmanr](https://github.com/huggingface/datasets/blob/master/metrics/spearmanr/spearmanr.py) both get input data as 'int32'. 


**Describe the solution you'd like**
- Considering that those metrics are widely used for the STS task(labels are in 'float' data type),
it would be better to modify datatype from 'int32' to 'float' for getting exact values of similarity.

Title: Split size error on `amazon_us_reviews` / `PC_v1_00` dataset
State: closed
Labels: description: Something isn't working
name: bug

description: Good for newcomers
name: good first issue

## Describe the bug
When downloading this subset as of 3-28-2022 you will encounter a split size error after the dataset is extracted. The extracted dataset has roughly ~6m rows while the split expects <1m. 

Upon digging a little deeper, I downloaded the raw files from `https://s3.amazonaws.com/amazon-reviews-pds/tsv/amazon_reviews_us_PC_v1_00.tsv.gz` and extracted them. A line count via `wc -l` confirms the ~6m number that we see and the data looks valid at a glance (I did not check for duplicate rows). My guess is this file has either been updated in place or there is a bug in the dataset metadata.

Happy to submit a PR and fix this up if turns out to be a metadata issue but wanted to get some other :eyes: on it first.

## Steps to reproduce the bug
```python
load_dataset('amazon_us_reviews', 'PC_v1_00')
```

## Expected results
Dataset is downloaded and extracted successfully.

## Actual results
An split size exception is thrown.

## Environment info
<!-- You can run the command `datasets-cli env` and copy-and-paste its output below. -->
- `datasets` version: 2.0.0
- Platform: Linux-5.10.16.3-microsoft-standard-WSL2-x86_64-with-glibc2.29
- Python version: 3.8.10
- PyArrow version: 7.0.0
- Pandas version: 1.4.1


Comments:
Follow-up: I have confirmed there are no duplicate lines via `sort amazon_reviews_us_PC_v1_00.tsv | uniq -cd` after extracting the raw file.

Hi @trentonstrong, thanks for reporting!

I confirm that loading this dataset configuration throws a `NonMatchingSplitsSizesError`:
```
NonMatchingSplitsSizesError: [{'expected': SplitInfo(name='train', num_bytes=350242049, num_examples=785730, dataset_name='amazon_us_reviews'), 'recorded': SplitInfo(name='train', num_bytes=3982712078, num_examples=6908554, dataset_name='amazon_us_reviews')}]
```

Also thank you for your offer to fix this. You can find information about how to update the metadata JSON file here: https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md#automatically-add-code-metadata
