Issue: Replace AssertionErrors with more meaningful errors
State: closed
Author: mariosasko

Replace the AssertionErrors with more meaningful errors such as ValueError, TypeError, etc.

The files with AssertionErrors that need to be replaced:
```
src/datasets/arrow_reader.py
src/datasets/builder.py
src/datasets/utils/version.py
```

Hi, can I pick up this issue?

#self-assign

Looks like the top-level `datasource` directory was removed when https://github.com/huggingface/datasets/pull/4974 was merged, so there are 3 source files to fix.
Issue: Restore saved format state in `load_from_disk`
State: closed
Author: asofiaoliveira

Hello! @mariosasko 

This pull request relates to issue #5050 and intends to add the format to datasets loaded from disk. 
All I did was add a set_format in the Dataset.load_from_disk, as DatasetDict.load_from_disk relies on the first.

I don't know if I should add a test and where, so let me know if I should and I can work on that as well!

Issue: Image & Audio formatting for numpy/torch/tf/jax
State: closed
Author: lhoestq

Added support for image and audio formatting for numpy, torch, tf and jax.

For images, the dtype used is the one of the image (the one returned by PIL.Image), e.g. uint8

I also added support for string, binary and None types. In particular for torch and jax, strings are kept unchanged (previously it was returning an error because you can't create a tensor of strings)

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

I just added a consolidation step so that numpy arrays or tensors of images are stacked together if the shapes match, instead of having lists of tensors

Feel free to review @mariosasko :)

I added a few lines in the docs and reverted the ragged numpy array change :)

ready for another review @mariosasko !
Issue: Support default config name when no builder configs
State: closed
Author: albertvillanova

**Is your feature request related to a problem? Please describe.**
As discussed with @stas00, we could support defining a default config name, even if no predefined allowed config names are set. That is, support `DEFAULT_CONFIG_NAME`, even when `BUILDER_CONFIGS` is not defined. 

**Additional context**
In order to support creating configs on the fly **by name** (not using kwargs), the list of allowed builder configs `BUILDER_CONFIGS` must not be set.

However, if so, then `DEFAULT_CONFIG_NAME` is not supported.


Comments:
Thank you for creating this feature request, Albert.

For context this is the datatest where Albert has been helping me to switch to on-the-fly split config https://huggingface.co/datasets/HuggingFaceM4/cm4-synthetic-testing

and the attempt to switch on-the-fly splits was here: https://huggingface.co/datasets/HuggingFaceM4/cm4-synthetic-testing/discussions/2/files

but which I had to revert since providing no split breaks at run time.

Issue: Fix backward compatibility for dataset_infos.json
State: closed
Author: lhoestq

While working on https://github.com/huggingface/datasets/pull/5018 I noticed a small bug introduced in #4926 regarding backward compatibility for dataset_infos.json

Indeed, when a dataset repo had both dataset_infos.json and README.md, the JSON file was ignored. This is unexpected: in practice it should be ignored only if the README.md has a dataset_info field, which has precedence over the data in the JSON file.

Issue: added from_generator method to IterableDataset class.
State: closed
Author: hamid-vakilzadeh

Hello, 

This resolves issues #4988.

I added a method `from_generator` to class `IterableDataset`.

I modified the `read` method of input stream generator to also return Iterable_dataset.


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

I added a test and moved the `streaming` param from `read` to `__init_`. Then, I also decided to update the `read` method of the rest of the packaged modules to account for this param. 

@hamid-vakilzadeh Are you OK with these changes? 

@mariosasko these all look great! Thanks for the updates.
Issue: Revert task removal in folder-based builders
State: closed
Author: mariosasko

Reverts the removal of `task_templates` in the folder-based builders. I also added the `AudioClassifaction` task for consistency.

This is needed to fix https://github.com/huggingface/transformers/issues/19177.

I think we should soon deprecate and remove the current task API (and investigate if it's possible to integrate the `train eval index` API), but we need to update the Transformers examples before that so we don't break them.

Issue: Fix bug with labels of eurlex config of lex_glue dataset
State: closed
Author: iliaschalkidis

Fix for a critical bug in the EURLEX dataset label list to make LexGLUE EURLEX results replicable. 

In LexGLUE (Chalkidis et al., 2022), the following is mentioned w.r.t. EUR-LEX: _"It supports four different label granularities, comprising 21, 127, 567, 7390 EuroVoc concepts, respectively. We use the 100 most frequent concepts from level 2 [...]”._ The current label list has all 127 labels, which leads to different (lower) results, as communicated by users.

Thanks!

- #4059
Issue: Audiofolder creates empty Dataset if files same level as metadata
State: closed
Author: msis

## Describe the bug
When audio files are at the same level as the metadata (`metadata.csv` or `metadata.jsonl` ), the `load_dataset` returns a `DatasetDict` with no rows but the correct columns.

https://github.com/huggingface/datasets/blob/1ea4d091b7a4b83a85b2eeb8df65115d39af3766/docs/source/audio_dataset.mdx?plain=1#L88

## Steps to reproduce the bug
`metadata.csv`:
```csv
file_name,duration,transcription
./2063_fe9936e7-62b2-4e62-a276-acbd344480ce_1.wav,10.768,hello
```


```python
>>> audio_dataset = load_dataset("audiofolder", data_dir="/audio-data/")
>>> audio_dataset
DatasetDict({
    train: Dataset({
        features: ['audio', 'duration', 'transcription'],
        num_rows: 0
    })
    validation: Dataset({
        features: ['audio', 'duration', 'transcription'],
        num_rows: 0
    })
})
```

I've tried, with no success,:
- setting `split` to something else so I don't get a `DatasetDict`,
- removing the `./`,
- using `.jsonl`.


## Expected results
```
 Dataset({
        features: ['audio', 'duration', 'transcription'],
        num_rows: 1
})
```

## Actual results
```
DatasetDict({
    train: Dataset({
        features: ['audio', 'duration', 'transcription'],
        num_rows: 0
    })
    validation: Dataset({
        features: ['audio', 'duration', 'transcription'],
        num_rows: 0
    })
})
```

Comments:
Hi! Unfortunately, I can't reproduce this behavior. Instead, I get `ValueError: audio at 2063_fe9936e7-62b2-4e62-a276-acbd344480ce_1.wav doesn't have metadata in /audio-data/metadata.csv`, which can be fixed by removing the `./` from the file name.

(Link to a Colab that tries to reproduce this behavior: https://colab.research.google.com/drive/1IhQzULYi0Van1xLrN_SddBX1JF7mLZZK?usp=sharing)

I think we can make the file name matching part more robust by replacing `file_name` with `os.path.normpath(file_name)`, to ignore "./" among other things, in these two places:
* https://github.com/huggingface/datasets/blob/85cd129bde605cd9acacdff0d065fc02e39e09b1/src/datasets/packaged_modules/folder_based_builder/folder_based_builder.py#L319

@mariosasko Some tests failed (see my PR). Any thoughts on that?

Yes, I mentioned the solution in my review.

I realized what I was doing wrong.

The documentation puts the files in a subfolder.
Once I have done that, it worked.

But l agree that this should be handled better if possible.

Issue: `Dataset.unique` showing wrong output after filtering
State: closed
Author: mxschmdt

## Describe the bug
After filtering a dataset, and if no samples remain, `Dataset.unique` will return the unique values of the unfiltered dataset.

## Steps to reproduce the bug
```python
from datasets import Dataset

dataset = Dataset.from_dict({'id': [0]})
dataset = dataset.filter(lambda _: False)
print(dataset.unique('id'))
```

## Expected results
The above code should return an empty list since the dataset is empty.

## Actual results
```bash
[0]
```

## Environment info
- `datasets` version: 2.5.1
- Platform: Linux-5.18.19-100.fc35.x86_64-x86_64-with-glibc2.34
- Python version: 3.9.14
- PyArrow version: 7.0.0

Comments:
Hi! It seems like `flatten_indices` (called in `unique`) doesn't know how to handle empty indices mappings. I'm working on the fix.

Issue: Add oversampling strategy iterable datasets interleave
State: closed
Author: ylacombe

Hello everyone,
Following the issue #4893 and the PR #4831, I propose here an oversampling strategy for a `IterableDataset` list.  
The `all_exhausted` strategy stops building the new dataset as soon as all samples in each dataset have been added at least once. 
It follows roughly the same logic behind #4831, namely:
- if ``probabilities`` is `None` and the strategy is `all_exhausted`, it simply performs a round robin interleaving that stops when the longest dataset is out of samples. Here the new dataset length will be $maxLengthDataset*nbDataset$.
- if ``probabilities`` is not `None` and the strategy is `all_exhausted`, it keeps trace of the datasets which were out of samples but continues to add them to the new dataset, and stops as soons as every dataset runs out of samples at least once.

In order to be consistent and also to align with the `Dataset` behavior, please note that the behavior of the default strategy (`first_exhausted`) has been changed. Namely, it really stops when a dataset is out of samples whereas it used to stop when receiving the `StopIteration` error.  
To give an example of the last note, with the following snippet:
```
>>> from tests.test_iterable_dataset import *
>>> d1 = IterableDataset(ExamplesIterable((lambda: (yield from [(i, {"a": i}) for i in [0, 1, 2]])), {}))
>>> d2 = IterableDataset(ExamplesIterable((lambda: (yield from [(i, {"a": i}) for i in [10, 11, 12, 13]])), {}))
>>> d3 = IterableDataset(ExamplesIterable((lambda: (yield from [(i, {"a": i}) for i in [20, 21, 22, 23, 24]])), {}))
>>> dataset = interleave_datasets([d1, d2, d3])
>>> [x["a"] for x in dataset]
```
The result here will then be `[10, 0, 11, 1, 2]` instead of `[10, 0, 11, 1, 2, 20, 12, 13]`.

I modified the behavior because I found it to be consistent with the under/oversampling approach and because it unified the undersampling and oversampling code, but I stay open to any suggestions.

Issue: new dataset type: single-label and multi-label video classification
State: open
Author: fcakyon

**Is your feature request related to a problem? Please describe.**
In my research, I am dealing with multi-modal (audio+text+frame sequence) video classification. It would be great if the datasets library supported generating multi-modal batches from a video dataset.

**Describe the solution you'd like**
Assume I have video files having single/multiple labels. I want to train a single/multi-label video classification model. I want datasets to support generating multi-modal batches (audio+frame sequence) from video files. Audio waveform and frame sequence can be extracted from each video clip then I can use any audio, image and video model from transformers library to extract features which will be fed into my model.

**Describe alternatives you've considered**
Currently, I am using https://github.com/facebookresearch/pytorchvideo dataloaders. There seems to be not much alternative.

**Additional context**
I am wiling to open a PR but don't know where to start.


Comments:
Hi ! You can in the `features` folder how we implemented the audio and image feature types.

We can have something similar to videos. What we need to decide:
- the video loading library to use
- the output format when a user accesses a video type object
- what parameters a `Video()` feature type needs

also cc @nateraw who also took a look at what we can do for video

@lhoestq @nateraw is there any progress on adding video classification datasets? 

Hi ! I think we just missing which lib we're going to use to decode the videos + which parameters must go in the `Video` type

Hmm. `decord` could be nice but it's no longer maintained [it seems](https://github.com/dmlc/decord/issues/214). 

pytorchvideo uses [pyav](https://github.com/PyAV-Org/PyAV) as the default decoder: https://github.com/facebookresearch/pytorchvideo/blob/c8d23d8b7e597586a9e2d18f6ed31ad8aa379a7a/pytorchvideo/data/labeled_video_dataset.py#L37

Also it would be great if `optionally` audio can also be decoded from the video as in pytorchvideo: https://github.com/facebookresearch/pytorchvideo/blob/c8d23d8b7e597586a9e2d18f6ed31ad8aa379a7a/pytorchvideo/data/labeled_video_dataset.py#L35

Here are the other decoders supported in pytorchvideo: https://github.com/facebookresearch/pytorchvideo/blob/c8d23d8b7e597586a9e2d18f6ed31ad8aa379a7a/pytorchvideo/data/encoded_video.py#L17


@sayakpaul I did do quite a bit of work on [this PR](https://github.com/huggingface/datasets/pull/4532) a while back to add a video feature. It's outdated, but uses my `encoded_video` [package](https://github.com/nateraw/encoded-video) under the hood, which is basically a wrapper around PyAV stolen from [pytorchvideo](https://github.com/facebookresearch/pytorchvideo/) that gets rid of the `torch` dependency. 

would be really great to get something like this in...it's just a really tricky and time consuming feature to add.
