glue datasets returning -1 for test split
Author: lithafnium | Pull request: no | State: closed

### Describe the bug

Downloading any dataset from GLUE has -1 as class labels for test split. Train and validation have regular 0/1 class labels.  This is also present in the dataset card online. 

### Steps to reproduce the bug

```
dataset = load_dataset("glue", "sst2")
for d in dataset:
    # prints out -1
    print(d["label"]
```

### Expected behavior

Expected behavior should be 0/1 instead of -1. 

### Environment info

- `datasets` version: 2.4.0
- Platform: Linux-5.15.0-46-generic-x86_64-with-glibc2.17
- Python version: 3.8.16
- PyArrow version: 8.0.0
- Pandas version: 1.5.3
Remove set_access_token usage + fail tests if FutureWarning
Author: Wauplin | Pull request: yes | State: closed

`set_access_token` is deprecated and will be removed in `huggingface_hub>=0.14`.

This PR removes it from the tests (it was not used in `datasets` source code itself). FYI, it was not needed since `set_access_token` was just setting git credentials and `datasets` doesn't seem to use git anywhere.

In the future, use `set_git_credential` if needed. It is a git-credential-agnostic helper, i.e. you can store your git token in `git-credential-cache`, `git-credential-store`, `osxkeychain`, etc. The legacy `set_access_token` could only set in `git-credential-store` no matter the user preference.

(for context, I found out about this while working on https://github.com/huggingface/huggingface_hub/pull/1381)

---

In addition to this, I have added

```
filterwarnings =
    error::FutureWarning:huggingface_hub*
```

to the `setup.cfg` config file to fail on future warnings from `huggingface_hub`. In `hfh`'s CI we trigger on FutureWarning from any package but it's less robust (any package update leads can lead to a failure). No obligation to keep it like that (I can remove it if you prefer) but I think it's a good idea in order to track future FutureWarnings.

FYI, in `huggingface_hub` tests we use `-Werror::FutureWarning --log-cli-level=INFO -sv --durations=0`
- FutureWarning are processed as error
- verbose mode / INFO logs (and above) are captured for easier debugging in github report
- track each test duration, just to see where we can improve. We have a quite long CI (~10min) so it helped improve that.
Bump pyarrow to 8.0.0

IterableDataset.add_column is unable to accept another IterableDataset as a parameter.
Author: zsaladin | Pull request: no | State: closed

### Describe the bug

`IterableDataset.add_column` occurs an exception when passing another `IterableDataset` as a parameter.
The method seems to accept only eager evaluated values.

https://github.com/huggingface/datasets/blob/35b789e8f6826b6b5a6b48fcc2416c890a1f326a/src/datasets/iterable_dataset.py#L1388-L1391


I wrote codes below to make it.
```py
def add_column(dataset: IterableDataset, name: str, add_dataset: IterableDataset, key: str) -> IterableDataset:
    iter_add_dataset = iter(add_dataset)

    def add_column_fn(example):
        if name in example:
            raise ValueError(f"Error when adding {name}: column {name} is already in the dataset.")
        return {name: next(iter_add_dataset)[key]}

    return dataset.map(add_column_fn)
```

Is there other way to do it? Or is it intended?

### Steps to reproduce the bug

Thie codes below occurs `NotImplementedError`
```py
from datasets import IterableDataset


def gen(num):
    yield {f"col{num}": 1}
    yield {f"col{num}": 2}
    yield {f"col{num}": 3}


ids1 = IterableDataset.from_generator(gen, gen_kwargs={"num": 1})
ids2 = IterableDataset.from_generator(gen, gen_kwargs={"num": 2})
new_ids = ids1.add_column("new_col", ids1)

for row in new_ids:
    print(row)
```

### Expected behavior

`IterableDataset.add_column` is able to task `IterableDataset` and lazy evaluated values as a parameter since IterableDataset is lazy evalued.

### Environment info
- `datasets` version: 2.8.0
- Platform: Linux-3.10.0-1160.36.2.el7.x86_64-x86_64-with-glibc2.17

Arrow map type in parquet files unsupported
Author: TevenLeScao | Pull request: no | State: open

### Describe the bug

When I try to load parquet files that were processed with Spark, I get the following issue:

`ValueError: Arrow type map<string, string ('warc_headers')> does not have a datasets dtype equivalent.`

Strangely, loading the dataset with `streaming=True` solves the issue.

### Steps to reproduce the bug

The dataset is private, but this can be reproduced with any dataset that has Arrow maps.

### Expected behavior

Loading the dataset no matter whether streaming is True or not.

### Environment info

- `datasets` version: 2.10.1
- Platform: Linux-5.15.0-1029-gcp-x86_64-with-glibc2.31
- Python version: 3.10.7

`load_from_disk` vs `load_dataset` performance.
Author: davidgilbertson | Pull request: no | State: open

### Describe the bug

I have downloaded `openwebtext` (~12GB) and filtered out a small amount of junk (it's still huge). Now, I would like to use this filtered version for future work. It seems I have two choices:
1. Use `load_dataset` each time, relying on the cache mechanism, and re-run my filtering.
2. `save_to_disk` and then use `load_from_disk` to load the filtered version.

The performance of these two approaches is wildly different:
* Using `load_dataset` takes about 20 seconds to load the dataset, and a few seconds to re-filter (thanks to the brilliant filter/map caching)
* Using `load_from_disk` takes 14 minutes! And the second time I tried, the session just crashed (on a machine with 32GB of RAM)

I don't know if you'd call this a bug, but it seems like there shouldn't need to be two methods to load from disk, or that they should  not take such wildly different amounts of time, or that one should not crash. Or maybe that the docs could offer some guidance about when to pick which method and why two methods exist, or just how do most people do it?

Something I couldn't work out from reading the docs was this: can I modify a dataset from the hub, save it (locally) and use `load_dataset` to load it? This [post seemed to suggest that the answer is no](https://discuss.huggingface.co/t/save-and-load-datasets/9260).

### Steps to reproduce the bug

See above

### Expected behavior

Load times should be about the same.

### Environment info

- `datasets` version: 2.9.0
- Platform: Linux-5.10.102.1-microsoft-standard-WSL2-x86_64-with-glibc2.31

audiofolder only creates dataset of 13 rows (files) when the data folder it's reading from has 20,000 mp3 files. 
Author: jcho19 | Pull request: no | State: closed

### Describe the bug

x = load_dataset("audiofolder", data_dir="x")
When running this, x is a dataset of 13 rows (files) when it should be 20,000 rows (files) as the data_dir "x" has 20,000 mp3 files. Does anyone know what could possibly cause this (naming convention of mp3 files, etc.)


### Steps to reproduce the bug

x = load_dataset("audiofolder", data_dir="x")


### Expected behavior

x = load_dataset("audiofolder", data_dir="x") should create a dataset of 20,000 rows (files).

### Environment info

- `datasets` version: 2.9.0

Fix outdated `verification_mode` values
Author: polinaeterna | Pull request: yes | State: closed

~I think it makes sense not to save `dataset_info.json` file to a dataset cache directory when loading dataset with `verification_mode="no_checks"` because otherwise when next time the dataset is loaded **without** `verification_mode="no_checks"`, it will be loaded successfully, despite some values in info might not correspond to the ones in the repo which was the reason for using `verification_mode="no_checks"` first.~

Updated values of `verification_mode` to the current ones in some places ("none" -> "no_checks", "all" -> "all_checks")
Problems with downloading The Pile
Author: sentialx | Pull request: no | State: closed

### Describe the bug

The downloads in the screenshot seem to be interrupted after some time and the last download throws a "Read timed out" error.

![image](https://user-images.githubusercontent.com/11065386/222687870-ec5fcb65-84e8-467d-9593-4ad7bdac4d50.png)

Here are the downloaded files:
![image](https://user-images.githubusercontent.com/11065386/222688200-454c2288-49e5-4682-96e6-1eb69aca0852.png)

They should be all 14GB like here (https://the-eye.eu/public/AI/pile/train/).

Alternatively, can I somehow download the files by myself and use the datasets preparing script?

### Steps to reproduce the bug

dataset = load_dataset('the_pile', split='train', cache_dir='F:\datasets')

### Expected behavior

The files should be downloaded correctly.

### Environment info

### Describe the bug

Get `Authorization error` when try to push data into hugginface datasets hub.

### Steps to reproduce the bug

I did all steps in the [tutorial](https://huggingface.co/docs/datasets/share), 

1. `huggingface-cli login` with WRITE token
2. `git lfs install`
3. `git clone https://huggingface.co/datasets/namespace/your_dataset_name`
4.
  ```
  cp /somewhere/data/*.json .
  git lfs track *.json
  git add .gitattributes
  git add *.json
  git commit -m "add json files"
  ```

but when I execute `git push` I got the error:

```
Uploading LFS objects:   0% (0/1), 0 B | 0 B/s, done.
batch response: Authorization error.
error: failed to push some refs to 'https://huggingface.co/datasets/zeusfsx/ukrainian-news'
```

Size of data ~100Gb.  I have five json files - different parts.

### Expected behavior

All my data pushed into hub

### Environment info

- `datasets` version: 2.10.1

Dataloader getitem not working for DreamboothDatasets
Author: salahiguiliz | Pull request: no | State: closed

### Describe the bug

 Dataloader getitem is not working as before (see example of [DreamboothDatasets](https://github.com/huggingface/peft/blob/main/examples/lora_dreambooth/train_dreambooth.py#L451C14-L529))
moving Datasets to 2.8.0 solved the issue.

### Steps to reproduce the bug

1- using DreamBoothDataset to load some images 
2- error after loading when trying to visualise the images 

### Expected behavior

I was expecting a numpy array of the image

### Environment info

in-place dataset update
Author: speedcell4 | Pull request: no | State: closed

### Motivation

For the circumstance that I creat an empty `Dataset` and keep appending new rows into it, I found that it leads to creating a new dataset at each call. It looks quite memory-consuming. I just wonder if there is any more efficient way to do this.

```python
from datasets import Dataset

ds = Dataset.from_list([])

ds.add_item({'a': [1, 2, 3], 'b': 4})
print(ds)
>>> Dataset({
>>>     features: [],
>>>     num_rows: 0
>>> })

ds = ds.add_item({'a': [1, 2, 3], 'b': 4})
print(ds)
>>> Dataset({
>>>     features: ['a', 'b'],
>>>     num_rows: 1
>>> })
```

### Feature request

Call for in-place dataset update functions, that update the existing `Dataset` in place without creating a new copy. The interface is supposed to keep the same style as PyTorch, such as the in-place version of a `function` is named `function_`. For example, the in-pace version of `add_item`, i.e., `add_item_`, immediately updates the `Dataset`.

```python
from datasets import Dataset

ds = Dataset.from_list([])

ds.add_item({'a': [1, 2, 3], 'b': 4})
print(ds)
>>> Dataset({
>>>     features: [],
>>>     num_rows: 0
>>> })

ds.add_item_({'a': [1, 2, 3], 'b': 4})
print(ds)
>>> Dataset({
>>>     features: ['a', 'b'],
>>>     num_rows: 1
>>> })
```

### Related Functions

* `.map`
* `.filter`
* `.add_item`

This reverts commit b91070b9c09673e2e148eec458036ab6a62ac042 (temporarily)

It hurts iterable dataset performance a lot (e.g. x4 slower because it encodes+decodes images unnecessarily). I think we need to fix this before re-adding it

.sort() is broken when used after .filter(), only in 2.10.0
Author: MattYoon | Pull request: no | State: closed

### Describe the bug

Hi, thank you for your support!

It seems like the addition of multiple key sort (#5502) in 2.10.0 broke the `.sort()` method.

After filtering a dataset with `.filter()`, the `.sort()` seems to refer to the query_table index of the previous unfiltered dataset, resulting in an IndexError.

This only happens with the 2.10.0 release.

### Steps to reproduce the bug

```Python
from datasets import load_dataset

# dataset with length of 1104
ds = load_dataset('glue', 'ax')['test']
ds = ds.filter(lambda x: x['idx'] > 1100)
ds.sort('premise')
print('Done')
```

  File "/home/dongkeun/datasets_test/test.py", line 5, in <module>
    ds.sort('premise')
  File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 528, in wrapper

  File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/fingerprint.py", line 511, in wrapper

    raise IndexError(f"Invalid key: {key} is out of bounds for size {size}")
IndexError: Invalid key: 1103 is out of bounds for size 3

### Expected behavior

It should sort the dataset and print "Done". Which it does on 2.9.0.

### Environment info

- `datasets` version: 2.10.0
- Platform: Linux-5.15.0-41-generic-x86_64-with-glibc2.31

Cache is not transportable
Author: davidgilbertson | Pull request: no | State: closed

### Describe the bug

I would like to share cache between two machines (a Windows host machine and a WSL instance).

I run most my code in WSL. I have just run out of space in the virtual drive. Rather than expand the drive size, I plan to move to cache to the host Windows machine, thereby sharing the downloads.

I'm hoping that I can just copy/paste the cache files, but I notice that a lot of the file names start with the path name, e.g. `_home_davidg_.cache_huggingface_datasets_conll2003_default-451...98.lock` where `home/davidg` is where the cache is in WSL. 

This seems to suggest that the cache is not portable/cannot be centralised or shared. Is this the case, or are the files that start with path names not integral to the caching mechanism? Because copying the cache files _seems_ to work, but I'm not filled with confidence that something isn't going to break.

A related issue, when trying to load a dataset that should come from cache (running in WSL, pointing to cache on the Windows host) it seemed to work fine, but it still uses a WSL directory for `.cache\huggingface\modules\datasets_modules`. I see nothing in the docs about this, or how to point it to a different place.

I have asked a related question on the forum: https://discuss.huggingface.co/t/is-datasets-cache-operating-system-agnostic/32656

### Steps to reproduce the bug

View the cache directory in WSL/Windows.

### Expected behavior

Cache can be shared between (virtual) machines and be transportable.

It would be nice to have a simple way to say "Dear Hugging Face packages, please put ALL your cache in `blah/de/blah`" and have all the Hugging Face packages respect that single location.

### Environment info

Support cloud storage in load_dataset via fsspec
Author: dwyatte | Pull request: yes | State: closed

Closes https://github.com/huggingface/datasets/issues/5281

This PR uses fsspec to support datasets on cloud storage (tested manually with GCS). ETags are currently unsupported for cloud storage. In general, a much larger refactor could be done to just use fsspec for all schemes (ftp, http/s, s3, gcs) to unify the interfaces here, but I ultimately opted to leave that out of this PR

I didn't create a GCS filesystem class in `datasets.filesystems` since the S3 one appears to be a wrapper around `s3fs.S3FileSystem` and mainly used to generate docs.
