Title: the_pile datasets URL broken. 
State: closed
Labels: description: Something isn't working
name: bug

https://github.com/huggingface/datasets/pull/3627 changed the Eleuther AI Pile dataset URL from https://the-eye.eu/ to https://mystic.the-eye.eu/ but the latter is now broken and the former works again. 

Note that when I git clone the repo and use `pip install -e .` and then edit the URL back the codebase doesn't seem to use this edit so the mystic URL is also cached somewhere else that I can't find? 

Comments:
Thanks for reporting, @TrentBrick. We are addressing the change with their data host server.

On the meantime, if you would like to work with your fixed local copy of the_pile script, you should use:
```python
load_dataset("path/to/your/local/the_pile/the_pile.py",...
```
instead of just `load_dataset("the_pile",...`.

The latter downloads a copy of `the_pile.py` from our GitHub, caches it locally (inside `~/.cache/huggingface/modules`) and uses that.

@TrentBrick, I have checked the URLs and both hosts work, the original (https://the-eye.eu/) and the mirror (https://mystic.the-eye.eu/). See e.g.:
- https://mystic.the-eye.eu/public/AI/pile/
- https://mystic.the-eye.eu/public/AI/pile_preliminary_components/

Please, let me know if you still find any issue loading this dataset by using current server URLs.

Great this is working now. Re the download from GitHub... I'm sure thought went into doing this but could it be made more clear maybe here? https://huggingface.co/docs/datasets/installation for example under installing from source? I spent over an hour questioning my sanity as I kept trying to edit this file, uninstall and reinstall the repo, git reset to previous versions of the file etc.

Thanks for the quick reply and help too


Thanks @TrentBrick for the suggestion about improving our docs: we should definitely do this if you find they are not clear enough.

Currently, our docs explain how to load a dataset from a local loading script here: [Load > Local loading script](https://huggingface.co/docs/datasets/loading#local-loading-script)

I've opened an issue here:
- #4732

Feel free to comment on it any additional explanation/suggestion/requirement related to this problem.
Title: Refactor conftest fixtures
State: closed

Previously, fixture modules `hub_fixtures` and `s3_fixtures`:
- were both at the root test directory
- were imported using `import *`
  - as a side effect, the modules `os` and `pytest` were imported from `s3_fixtures` into `conftest`

This PR:
- puts both fixture modules in a dedicated directory `fixtures`
- renames both to: `fixtures.hub` and `fixtures.s3`
- imports them into `conftest` as plugins, using the `pytest_plugins`: this avoids the `import *`
- additionally creates a new fixture module `fixtures.files` with all file-related fixtures

`href="/docs/datasets/quickstart#audio"` implicitly goes to `href="/docs/datasets/{$LATEST_STABLE_VERSION}/quickstart#audio"`. Therefore, https://huggingface.co/docs/datasets/quickstart#audio #audio hashlink does not work since the new docs were not added to v2.3.2 (LATEST_STABLE_VERSION)

to preserve the version, it should be just `href="#audio"`, which will implicilty go to curren_page + #audio element

Title: Issue loading TheNoob3131/mosquito-data dataset
State: closed

So my dataset is public in the Huggingface Hub, but when I try to load it using the load_dataset command, it shows that it is downloading the files, but throws a ValueError. When I went to my directory to see if the files were downloaded, the folder was blank.

Here is the error below:
ValueError                                Traceback (most recent call last)

Is the dataset in the wrong format or is there some security permission that I should enable?

Comments:
I am also getting a ValueError: 'Couldn't cast' at the bottom. Is this because of some delimiter issue? My dataset is on the Huggingface Hub. If you could look at it, that would be greatly appreciated.

Hi @thenerd31, thanks for reporting.

Please note that your issue is not caused by the Hugging Face Datasets library, but it has to do with the specific implementation of your dataset on the Hub.

Therefore, I'm transferring this discussion to your own dataset Community tab: https://huggingface.co/datasets/TheNoob3131/mosquito-data/discussions/1

Title: Support "tags" yaml tag

Added the "tags" YAML tag, so that users can specify data domain/topics keywords for dataset search

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

IMO `DatasetMetadata` shouldn't crash with attributes that it doesn't know, btw

Yea this PR is mostly to have a validation that this field contains a list of strings.

Regarding unknown fields, the tagging app currently returns an error if a field is unknown using the `DatasetMetadata`. We can change that though

CI failures are about missing content in the dataset cards or bad tags, and this is unrelated to this PR. Merging :)

Title: Document how to create a dataset loading script for audio/vision
State: closed
Labels: description: Improvements or additions to documentation
name: documentation

Currently, in our docs for Audio/Vision/Text, we explain how to:
- Load data
- Process data

However we only explain how to *Create a dataset loading script* for text data.

I think it would be useful that we add the same for Audio/Vision as these have some specificities different from Text.

See, for example:
- #4697
  - and comment there: https://github.com/huggingface/datasets/issues/4697#issuecomment-1191502492

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

Great idea! Now that we have more than one task, it makes sense to separate image classification and object detection so it'll be easier for users to follow.

@lhoestq do we want to do that in this PR, or should we merge it and let @stevhliu reorganize separately?
Title: Fix require torchaudio and refactor test requirements
State: closed

Currently there is a bug in `require_torchaudio` (indeed it is requiring `sox` instead):
```python
def require_torchaudio(test_case):
    if find_spec("sox") is None:
...
```

The bug was introduced by:
- #3685
  - Commit: https://github.com/huggingface/datasets/pull/3685/commits/b5a3e7122d49c4dcc9333b1d8d18a833fc04b940

which moved
```python
require_sndfile = pytest.mark.skipif(
    # In Windows and OS X, soundfile installs sndfile
    (sys.platform != "linux" and find_spec("soundfile") is None)
    # In Linux, soundfile throws RuntimeError if sndfile not installed with distribution package manager
    or (sys.platform == "linux" and find_library("sndfile") is None),

This PR;
- fixes the bug in `require_torchaudio`
- refactors the test requirements back to using `pytest` instead of `unittest`
  - the text in `pytest.skipif` `reason` can be used if needed in a test body: `require_torchaudio.kwargs["reason"]`

We will investigate why it occurred in the first place


By chance, could you provide some details about the operations done on the dataset: was it private? gated?

Yes, it was a private dataset, and when I made it public, the Dataset Preview did not work. 

However, now when I make the dataset private, it says that the Dataset Preview has been disabled. Why is this?

Thanks for the details. For now, the dataset viewer is always disabled on private datasets (see https://huggingface.co/docs/hub/datasets-viewer for more details)

Hi, it was working fine for a few hours, but then I can't see the dataset viewer again (public dataset). Why is this still happening?
It's the same error too:

OK? This is a bug, thanks for help spotting and reproducing it (it occurs when a dataset is switched to private, then to public). We will be working on it, meanwhile, I've restored the dataset viewer manually again.

Currently, if `zstandard` or `lz4` are not installed, `test_compression_filesystems` and `test_streaming_dl_manager_extract_all_supported_single_file_compression_types` are skipped for all compression format parameters.

This PR fixes these tests, so that if `zstandard` or `lz4` are not installed, the tests are skipped only for the corresponding compression parameters (`zstd` or `lz4`), whereas the tests are not skipped for all the other compression parameters (`gzip`, `xz` and `bz2`).

Title: Fix Authentification Error while streaming
State: closed

I fixed a few errors when it occurs while streaming the private dataset on the Huggingface Hub.
```
from datasets import load_dataset

dataset = load_dataset(<repo_id>, use_auth_token=<private_token>, streaming=True)
for d in dataset['train']:
    print(d)
    break # this is for checking
```
This code is an example for streaming private datasets. 
when the version of the datasets is 2.2.2, it works well but datasets>2.2.2 occurs error like this,
```
/usr/local/lib/python3.7/dist-packages/aiohttp/client_reqrep.py in raise_for_status(self)
1007 status=self.status,
1008 message=self.reason,
→ 1009 headers=self.headers,
1010 )
1011

ClientResponseError: 401, message='Unauthorized', url=URL('https://huggingface.co/datasets/.../train-00000-of-00001-168b451062c67c34.parquet')
```
(this is an example on the dataset has `parquet` extenstion)
It seems that the `xisfile `module in `download/streaming_download_manager.py` couldn't recognize the file on "https://huggingface.co/~".

so I add three lines.
With this change, there is no error anymore(but this code is ad-hoc).

Title: Enable streaming dataset to use the "all" split
State: closed

Fixes #4637

Comments:
The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/datasets/pr_4698). All of your documentation changes will be reflected on that endpoint.

@albertvillanova 
Adding the validation split causes these two `assert_called_once` assertions to fail with `AssertionError: Expected 'ArrowWriter' to have been called once. Called 2 times`:

https://github.com/huggingface/datasets/blob/main/tests/test_builder.py#L548-L562

It might be better to create a new dummy generator for the streaming tests, WDYT? Alternatively we could test for `self.call_count` equalling 2.

@cakiki have you read my comment in the issue page?
https://github.com/huggingface/datasets/issues/4637#issuecomment-1175984812

Streaming with `split=all` seems to be working, will fix the failing test next

Not sure if marking the PR as "ready for review" actually notified you, so tagging @albertvillanova just in case :smiley_cat:

Hi @cakiki, still interested in working on this? :) 

@albertvillanova So sorry; I have no idea how this slipped through the cracks. Yes, I'd still like to work on this. Is it okay if I DM you on slack?

Title: Distributed data parallel training for streaming datasets
State: open
Labels: description: New feature or request
name: enhancement

### Feature request

Any documentations for the the `load_dataset(streaming=True)` for (multi-node multi-GPU) DDP training? 

### Motivation

Given a bunch of data files, it is expected to split them onto different GPUs. Is there a guide or documentation?

### Your contribution

Does it requires manually split on data files for each worker in `DatasetBuilder._split_generator()`? What is`IterableDatasetShard` expected to do?

Comments:
Hi ! According to https://huggingface.co/docs/datasets/use_with_pytorch#stream-data you can use the pytorch DataLoader with `num_workers>0` to distribute the shards across your workers (it uses `torch.utils.data.get_worker_info()` to get the worker ID and select the right subsets of shards to use)


 EDIT: here is a code example 

```python
# ds = ds.with_format("torch")
# dataloader = DataLoader(ds, num_workers=num_workers)
```

EDIT: `with_format("torch")` is not required, now you can just do
```python
dataloader = DataLoader(ds, num_workers=num_workers)
```

@cyk1337 does streaming datasets with multi-gpu works for you? I am testing on one node with multiple gpus, but this is freezing, https://github.com/huggingface/datasets/issues/5123 
In case you could make this work, could you share with me your data-loading codes?
thank you

+1

This has been implemented in `datasets` 2.8:
```python
from datasets.distributed import split_dataset_by_node

ds = split_dataset_by_node(ds, rank=rank, world_size=world_size)
```

docs: https://huggingface.co/docs/datasets/use_with_pytorch#distributed

i'm having hanging issues with this when using DDP and allocating the datasets with `split_dataset_by_node` 🤔

--- 
### edit
I don't want to pollute this thread, but for the sake of following up, I observed hanging close to the final iteration of the dataloader. I think this was happening on the final shard. First, I removed the final shard and things worked. Then (including all shards), I reordered the list of shards: `load_dataset('json', data_files=reordered, streaming=True)` and no hang. 

I won't open an issue yet bc I am not quite sure about this observation.

@wconnell would you mind opening a different bug issue and giving more details?

Title: Refactor base extractors
State: closed

This PR:
- Refactors base extractors as subclasses of `BaseExtractor`:
  - this is an abstract class defining the interface with:
    - `is_extractable`: abstract class method
    - `extract`: abstract static method
- Implements abstract `MagicNumberBaseExtractor` (as subclass of `BaseExtractor`): 
  - this has a default implementation of `is_extractable`
  - this improves performance (reducing the number of file reads) by allowing passing already read `magic_number`
- Refactors `Extractor`:
  - reads magic number from file only once

This PR deprecates:
```python
is_extractable, extractor = self.extractor.is_extractable(input_path, return_extractor=True)
self.extractor.extract(input_path, output_path, extractor=extractor)
```
and uses more Pythonic instead:
```python
extractor_format = self.extractor.infer_extractor_format(input_path)
self.extractor.extract(input_path, output_path, extractor_format)
```
