Issue: Add a robustness benchmark dataset for vision
State: open
Author: sayakpaul

### Name

ImageNet-C

### Paper

Benchmarking Neural Network Robustness to Common Corruptions and Perturbations

### Data

https://github.com/hendrycks/robustness

### Motivation

It's a known fact that vision models are brittle when they meet with slightly corrupted and perturbed data. This is also correlated to the robustness aspects of vision models. 

Researchers use different benchmark datasets to evaluate the robustness aspects of vision models. ImageNet-C is one of them. 

Having this dataset in 🤗 Datasets would allow researchers to evaluate and study the robustness aspects of vision models. Since the metric associated with these evaluations is top-1 accuracy, researchers should be able to easily take advantage of the evaluation benchmarks on the Hub and perform comprehensive reporting. 

ImageNet-C is a large dataset. Once it's in, it can act as a reference and we can also reach out to the authors of the other robustness benchmark datasets in vision, such as ObjectNet, WILDS, Metashift, etc. These datasets cater to different aspects. For example, ObjectNet is related to assessing how well a model performs under sub-population shifts.

Issue: Fix remove columns from lazy dict
State: closed
Author: lhoestq

This was introduced in https://github.com/huggingface/datasets/pull/5252 and causing the transformers CI to break: https://app.circleci.com/pipelines/github/huggingface/transformers/53886/workflows/522faf2e-a053-454c-94f8-a617fde33393/jobs/648597

Basically this code should return a dataset with only one column:

```python
from datasets import *

ds = Dataset.from_dict({"a": range(5)})

def f(x):
    x["b"] = x["a"]
    return x

ds = ds.map(f, remove_columns=["a"])

assert ds.column_names == ["b"]
```

Issue: Run 'GPT-J' failure due to download dataset fail (' ConnectionError: Couldn't reach http://eaidata.bmk.sh/data/enron_emails.jsonl.zst ' ) 
State: closed
Author: shaoyuta

### Describe the bug

Run model "GPT-J" with dataset "the_pile" fail.
The fail out is as below:
![image](https://user-images.githubusercontent.com/52023469/207750127-118d9896-35f4-4ee9-90d4-d0ab9aae9c74.png)

Looks like which is due to "http://eaidata.bmk.sh/data/enron_emails.jsonl.zst" unreachable .

### Steps to reproduce the bug

Steps to reproduce this issue:

git clone https://github.com/huggingface/transformers
cd transformers
python examples/pytorch/language-modeling/run_clm.py --model_name_or_path EleutherAI/gpt-j-6B --dataset_name the_pile --dataset_config_name enron_emails --do_eval --output_dir /tmp/output --overwrite_output_dir

### Expected behavior

This issue looks like due to "http://eaidata.bmk.sh/data/enron_emails.jsonl.zst " couldn't be reached.
Is there another way to download the dataset "the_pile" ?
Is there another way to cache the dataset "the_pile" but not let the hg to download it when runtime ?

Comments:
Thanks for reporting, @shaoyuta.

We have checked and yes, apparently there is an issue with the server hosting the data of the "enron_emails" subset of "the_pile" dataset: http://eaidata.bmk.sh/data/enron_emails.jsonl.zst
It seems to be down: The connection has timed out.

Please note that at the Hugging Face Hub, we are not hosting their data for this dataset, but only a script that downloads the data from their servers. We are updating the data URL to one in another server.

In the meantime, please note that you can train your model in the entire "the_pile" dataset, by passing the "all" config (instead of the "enron_emails" one).

We have transferred this issue to the corresponding dataset Community tab: https://huggingface.co/datasets/the_pile/discussions/2

Please, follow the updates there.
Issue: Raise error if ClassLabel names is not python list

Checks type of names provided to ClassLabel to avoid easy and hard to debug errors (closes #5332 - see for discussion)

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

Thanks for your proposed fix, @freddyheppell.

Currently the CI fails because in a test we pass a `tuple` instead of a `list`. I would say we should accept `tuple` as a valid input type as well...

What about checking for `Sequence` instead?

Fixed that @albertvillanova, can you approve CI again please? Had some issues related to Pytorch .so files when running tests on my M1 mac, so wasn't able to test locally first. Have got them working on my desktop now though.
Issue: Support torch dataloader without torch formatting
State: closed
Author: lhoestq

In https://github.com/huggingface/datasets/pull/5084 we make the torch formatting consistent with the map-style datasets formatting: a torch formatted iterable dataset will yield torch tensors.

The previous behavior of the torch formatting for iterable dataset was simply to make the iterable dataset inherit from `torch.utils.data.Dataset` to make it work in a torch DataLoader. However ideally an unformatted dataset should also work with a DataLoader. To fix that, `datasets.IterableDataset` should inherit from `torch.utils.data.IterableDataset`.

Since we don't want to import torch on startup, I created this PR to dynamically make the `datasets.IterableDataset` class inherit form the torch one when a `datasets.IterableDataset` is instantiated and if PyTorch is available.

```python
>>> from datasets import load_dataset
>>> ds = load_dataset("c4", "en", streaming=True, split="train")
>>> import torch.utils.data
>>> isinstance(ds, torch.utils.data.IterableDataset)
True
>>> dataloader = torch.utils.data.DataLoader(ds, batch_size=32, num_workers=4)
>>> for example in dataloader:
...:     ...
```

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

Need some more time to fix the tests, especially with pickle

> And I actually don't quite understand the idea - what's the motivation behind making only IterableDataset compatible with torch DataLoader without setting the format explicitly?

Setting the format to pytorch = set the output types of the dataset to be pytorch tensors. However sometimes your dataset is not made of tensors but you still want to be able to use a pytorch DataLoader

A bit more context. 

The arrow-backed `Dataset` supports `DataLoader(ds)` (even if the format is not "torch"), and we want to be able to do the same with `IterableDataset` for consistency. However, this is when the PyTorch internals come into play - an iterable dataset needs to be an instance of `torch.utils.data.IterableDataset` due to [this](https://github.com/pytorch/pytorch/blob/abc54f93145830b502400faa92bec86e05422fbd/torch/utils/data/dataloader.py#L276) check (notice there is no check for the map-style version). Hence the explicit subclassing in this PR.

Exactly :) Btw I just took your comments into account @polinaeterna , so feel free to review again

@lhoestq just checking, does this change still preserve the fix to the "data duplicate when setting num_works > 1 with streaming data" issue from before?

Yes :)
Issue: Support remote file systems for `Audio`
State: closed
Author: OllieBroadhurst

### Feature request

Hi there!

It would be super cool if `Audio()`, and potentially other features, could read files from a remote file system.

### Motivation

Large amounts of data is often stored in buckets. `load_from_disk` is able to retrieve data from cloud storage but to my knowledge actually copies the datasets across first, so if you're working off a system with smaller disk specs (like a VM), you can run out of space very quickly.

### Your contribution

Something like this (for Google Cloud Platform in this instance):



```python
from datasets import Dataset, Audio
import gcsfs

fs = gcsfs.GCSFileSystem()

list_of_audio_fp = {'audio': ['1', '2', '3']}
ds = Dataset.from_dict(list_of_audio_fp)

ds = ds.cast_column("audio", Audio(sampling_rate=16000, fs=fs))
```

Under the hood:
```python

import librosa
from io import BytesIO

def load_audio(fp, sampling_rate=None, fs=None):
    if fs is not None:
        with fs.open(fp, 'rb') as f:
            arr, sr = librosa.load(BytesIO(f), sr=sampling_rate)
    else:
        # Perform existing io operations
```

Written from memory so some things could be wrong.

Just seen https://github.com/huggingface/datasets/issues/5281
Issue: __init__() got an unexpected keyword argument 'input_size'
State: open
Author: J-shel

### Describe the bug

I try to define a custom configuration with a input_size attribute following the instructions by "Specifying several dataset configurations" in https://huggingface.co/docs/datasets/v1.2.1/add_dataset.html

But when I load the dataset, I got an error "__init__() got an unexpected keyword argument 'input_size'"

### Steps to reproduce the bug

Following is the code to define the dataset:
class CsvConfig(datasets.BuilderConfig):
    """BuilderConfig for CSV."""
    input_size: int = 2048

class MRF(datasets.ArrowBasedBuilder):
    """Archival MRF data"""
    BUILDER_CONFIG_CLASS = CsvConfig
    VERSION = datasets.Version("1.0.0")
    BUILDER_CONFIGS = [
        CsvConfig(name="default", version=VERSION, description="MRF data", input_size=2048),
    ]

...

    def _generate_examples(self):
        input_size = self.config.input_size
        if input_size > 1000:
           numin = 10000
        else:
           numin = 15000


Below is the code to load the dataset:
reader = load_dataset("default", input_size=1024)

### Expected behavior

I hope to pass the "input_size" parameter to MRF datasets, and change "input_size" to any value when loading the datasets. 

### Environment info

- `datasets` version: 2.5.1
- Platform: Linux-4.18.0-305.3.1.el8.x86_64-x86_64-with-glibc2.31
- Python version: 3.9.12
- PyArrow version: 9.0.0
- Pandas version: 1.5.0

Comments:
Hi @J-shel, thanks for reporting.

I think the issue comes from your call to `load_dataset`. As first argument, you should pass:
- either the name of your dataset ("mrf") if this is already published on the Hub
- or the path to the loading script of your dataset ("path/to/your/local/mrf.py").

Hi, following your suggestion, I changed my call to load_dataset. Below is the latest:
reader = load_dataset('data/mrf.py',"default", input_size=1024, split=split, streaming=True, keep_in_memory=None)
However, I still got the same error.
I have one question that is if I only define input_size=2048 in BUILDER_CONFIGS, may I specify input_size=1024 when loading the dataset?  Cause I found that I could only specify name="default" since I only define  name="default" in BUILDER_CONFIGS.

Cool ! Feel free to add a comment in the code to explain that and we can merge :)

I'm not sure if this is a good change since we plan to get rid of `torchaudio` in the next couple of months...

What do you think @polinaeterna @patrickvonplaten ? Models are usually using float32 (e.g. Wev2vec2 in `transformers`) IIRC

IMO we can safely assume that float32 is always good enough when using audio models in inference or training. Nevertheless there might be use cases for audio datasets in the future where float64 is needed. 

=> I would by default always cast to float32, but then possible allow the user to cast to float64 

> I'm not sure if this is a good change since we plan to get rid of torchaudio in the next couple of months...

@mariosasko I agree but who knows how long we will have to wait until we are really able to do so (https://github.com/bastibe/libsndfile-binaries/pull/17 is a draft. so as @patrickvonplaten is okay with float32, I'd merge.




@polinaeterna Can you comment on the linked PR to see why it's still a draft? Maybe we can help somehow to get this merged finally.

I think it's weird to align `soundfile` with `torchaudio` when the latter is only used for MP3 (and prob for not much longer).

@lhoestq I think I need some serious help with the tests 😅...I started this locally but it got too time consuming.

One issue I remember running into is with lossless audio encoding/decoding. I started thinking of using the underlying Audio feature instead of PyAV so I didn't have to rewrite similar logic here...but assumed that would turn into a mess w/ underlying logic

Are you still planning to work on this?

Issue: `map()` stops every 1000 steps
State: closed
Author: bayartsogt-ya

### Describe the bug

I am passing the following `prepare_dataset` function to `Dataset.map` (code is inspired from [here](https://github.com/huggingface/community-events/blob/main/whisper-fine-tuning-event/run_speech_recognition_seq2seq_streaming.py#L454))
```python3
def prepare_dataset(batch):
    # load and resample audio data from 48 to 16kHz
    audio = batch["audio"]

    # compute log-Mel input features from input audio array 
    batch["input_features"] = feature_extractor(audio["array"], sampling_rate=audio["sampling_rate"]).input_features[0]

    # encode target text to label ids 
    batch["labels"] = tokenizer(batch[text_column]).input_ids
    return batch
...
train_ds = train_ds.map(prepare_dataset)
```

Here is the exact code I am running https://github.com/bayartsogt-ya/whisper-multiple-hf-datasets/blob/main/train.py#L70-L71

It starts using all the cores (I am not sure why because I did not pass `num_proc`)
then progress bar stops at every 1k steps. (starts using a single core)
then come back to using all the cores again.

link to [screen record](https://youtu.be/jPQpQQGp6Gc)

Can someone explain this process and maybe provide a way to improve this pipeline? cc: @lhoestq 

### Steps to reproduce the bug

1. load the dataset
2. create a Whisper processor
3. create a `prepare_dataset` function
4. pass the function to `dataset.map(prepare_dataset)`

### Expected behavior

- Use a single core per a function
- not to stop at some point?

### Environment info

- `datasets` version: 2.7.1.dev0
- Platform: Linux-5.4.0-109-generic-x86_64-with-glibc2.27
- Python version: 3.8.10
- PyArrow version: 10.0.1
- Pandas version: 1.5.2

Comments:
Hi !

> It starts using all the cores (I am not sure why because I did not pass num_proc)

The tokenizer uses Rust code that is multithreaded. And maybe the `feature_extractor` might run some things in parallel as well - but I'm not super familiar with its internals.

> then progress bar stops at every 1k steps. (starts using a single core)

Every 1000 examples we flush the processed examples to disk. It is this way because Arrow is a columnar format: you must write data chunk by chunk. The processing in on hold while writing right now - maybe this can be improved in the future.

Hi @lhoestq 
Thanks for the explanation! it was so helpful! Let me check why `feature_extractor` is running on multiple cpus.

Hey @lhoestq, any news about this flush operation ? This really really slow down most of my .map and .filter operation. I'm sometime taking 10x more time waiting for the flush than actually processing the 1k items. My current workarround is to set `writer_batch_size=len(dataset)`.
Issue: Support webdataset format
State: closed
Author: lhoestq

Webdataset is an efficient format for iterable datasets. It would be nice to support it in `datasets`, as discussed in https://github.com/rom1504/img2dataset/issues/234.

In particular it would be awesome to be able to load one using `load_dataset` in streaming mode (either from a local directory, or from a dataset on the Hugging Face Hub). Some datasets on the Hub are already in webdataset format.

It terms of implementation, we can have something similar to the Parquet loader.
I also think it's fine to have webdataset as an optional dependency.

Comments:
I like the idea of having `webdataset` as an optional dependency to ensure our loader generates web datasets the same way as the main project.

Webdataset is the one of the most popular dataset formats for large scale computer vision tasks. Upvote for this issue. 

Any updates on this?

We haven't had the bandwidth to implement it so far, but if someone wants to give it a shot please don't hesitate ^^

Issue: Set `IterableDataset.map` param `batch_size` typing as optional
State: closed
Author: alvarobartt

This PR solves #5325 

~Indeed we're using the typing for optional values as `Union[type, None]` as it's similar to how Python 3.10 handles optional values as `type | None`, instead of using `Optional[type]`.~

~Do we want to start using `Union[type, None]` for type-hinting optional values or just keep on using `Optional`?~ -> Keeping `Optional` still for consistency with the rest of the code in `datasets`

Also we now allow `batch_size` to be `None` for `IterableDataset.map` and `IterableDataset.filter`e.g. `MappedExamplesIterable` as `map` is internally instantiating those and propagating the `batch_size` param so if it can be `None` for `map` it should also do so for `MappedExamplesIterable`, as well as for `FilteredExamplesIterable` when calling `IterableDataset.filter`.

## TODOs

- [x] Add integration tests
- [x] Handle scenario where `batched=True` and `batch_size=None` or `batch_size<=0`

Hi @mariosasko, @lhoestq I was wondering whether we should include `batched` as a `pytest.mark` param for the functions testing `IterableDataset.map` so as to ensure that the changes done in this PR work fine without breaking anything of the actual functionality.

I've pushed updated tests just for one of the unit testing functions to be run as `pytest tests/test_iterable_dataset.py::test_mapped_examples_iterable -s --durations 0`, but some are still missing `batched` param, it was just to ask you whether we're supposed to do this for the rest of the functions or not, if it's a yes I'll push the commit as it's ready, but didn't want to push extra stuff that may be discarded later!

Thanks :hugs:

Thanks for the feedback @lhoestq, I agree with keeping `Optional` instead of `Union[type, None]` for now 👍🏻
