set_format does not work with multi dimension tensor
State: closed | Author: phihung (NONE)
Labels: name: bug

## Describe the bug
set_format only transforms the last dimension of a multi-dimension list to tensor

## Steps to reproduce the bug
```python
import torch
from datasets import Dataset

ds = Dataset.from_dict({"A": [torch.rand((2, 2))]})
# ds = Dataset.from_dict({"A": [np.random.rand(2, 2)]})  # => same result
ds = ds.with_format("torch")
print(ds[0])
```

## Expected results
```
{'A': [tensor([[0.6689, 0.1516], [0.1403, 0.5567]])]}
```

## Actual results
```
{'A': [tensor([0.6689, 0.1516]), tensor([0.1403, 0.5567])]}
```

## Environment info
<!-- You can run the command `datasets-cli env` and copy-and-paste its output below. -->

Comments: Hi! Use the `ArrayXD` feature type (where X is the number of dimensions) to get correctly formated tensors. So in your case, define the dataset as follows :
```python
ds = Dataset.from_dict({"A": [torch.rand((2, 2))]}, features=Features({"A": Array2D(shape=(2, 2), dtype="float32")}))
```


Hi @mariosasko I'm facing the same issue and the only work around I've found so far is to convert my `DatasetDict` to a dictionary and then create new objects with `Dataset.from_dict`.
```
dataset = load_dataset("my_dataset.py")
dataset = dataset.map(lambda example: blabla(example))
dict_dataset_test = dataset["test"].to_dict()
...
dataset_test = Dataset.from_dict(dict_dataset_test, features=Features(features))
```
However, converting a `Dataset` object to a dict takes quite a lot of time and memory... Is there a way to directly create an `Array2D` without having to transform the original `Dataset` to a dict?

Hi! Yes, you can directly pass the `Features` dictionary as `features` in `map` to cast the column to `Array2D`:
```python
dataset = dataset.map(lambda example: blabla(example), features=Features(features))
```
Or you can use `cast` after `map` to do that:
```python
dataset = dataset.map(lambda example: blabla(example))
dataset = dataset.cast(Features(features))
```

Fantastic thank you @mariosasko
The first option you suggested is indeed way faster 😃
Use audio feature in ASR task template
State: closed | Author: lhoestq (MEMBER)

The AutomaticSpeechRecognition task template is outdated: it still uses the file path column as input instead of the audio column.

I changed that and updated all the datasets as well as the tests.

The only community dataset that will need to be updated is `facebook/multilingual_librispeech`. It has almost zero usage unfortunately (probably because users load the duplicate `multilingual_librispeech` directly instead), but it means we can update it.

(this makes me think that we should deprecate `multilingual_librispeech` it and redirect users to `facebook/multilingual_librispeech`).

This PR is also useful for the AudioFolder in https://github.com/huggingface/datasets/pull/3963

Sync Features dictionaries
State: closed | Author: mariosasko (COLLABORATOR)

This PR adds a wrapper to the `Features` class to keep the secondary dict, `_column_requires_decoding`, aligned with the main dict (as discussed in https://github.com/huggingface/datasets/pull/3723#discussion_r806912731).

A more elegant approach would be to subclass `UserDict` and override `__setitem__` and `__delitem__`, but this PR doesn't implement it for the following reasons:
* it requires replacing all occurrences of `isinstance(obj, dict)` with `isinstance(obj, Mapping)`, which is five times slower than `isinstance(obj, dict)` on my machine, in `features.py`
* is a breaking change, i.e., `isinstance(Features(...), dict)` would return `False` after it
* IMO, it makes sense to be consistent in the user-facing API and subclass either `dict` or `UserDict`. The problem with the latter is that it can't be used for `DatasetDict` because `DatasetDict` exposes the `data` property, which is also used by `UserDict`, so this would result in a collision.

Close `PIL.Image` file handler in `Image.decode_example`
State: closed | Author: mariosasko (COLLABORATOR)

Closes the file handler of the PIL image object in `Image.decode_example` to avoid the `Too many open files` error.

To pass [the image equality checks](https://app.circleci.com/pipelines/github/huggingface/datasets/10774/workflows/d56670e6-16bb-4c64-b601-a152c5acf5ed/jobs/65825) in CI, `Image.decode_example` calls `image.load()` regardless of how the image object is created (not only for the `PIL.Image.open(local_path)` case). This is needed because `load()` sets the `readonly` attribute of a `PIL.Image` object to 0 (it's 1 after `PIL.Image.open(file_like)`), and in the older PIL versions (only fixed on main), that attribute is considered in `PIL.Image.__eq__`. More info can be found here: https://github.com/python-pillow/Pillow/issues/5926.

Streaming dataset + interleave + DataLoader hangs with multiple workers
State: open | Author: jpilaul (NONE)
Labels: name: bug

## Describe the bug
Interleaving multiple iterable datasets that use `load_dataset` on streaming mode hangs when passed to `torch.utils.data.DataLoader` with multiple workers.

## Steps to reproduce the bug
```python
from datasets import interleave_datasets, load_dataset
from torch.utils.data import DataLoader

en_dataset = load_dataset('oscar', "unshuffled_deduplicated_en", split='train', streaming=True)
fr_dataset = load_dataset('oscar', "unshuffled_deduplicated_fr", split='train', streaming=True)
it_dataset = load_dataset('oscar', "unshuffled_deduplicated_it", split='train', streaming=True)
de_dataset = load_dataset('oscar', "unshuffled_deduplicated_de", split='train', streaming=True)
multilingual_dataset = interleave_datasets([en_dataset, fr_dataset, de_dataset, it_dataset])
multilingual_dataset = multilingual_dataset.with_format('torch')

next(iter(multilingual_dataset))  # works fairly fast

dataloader = DataLoader(multilingual_dataset, batch_size=8, num_workers=4)
for batch in dataloader:
    print(len(batch))  # prints nothing after 30 min of waiting

dataloader = DataLoader(multilingual_dataset, batch_size=8, num_workers=0)
for batch in dataloader:
    print(len(batch))  # prints right away

```

## Expected results
It should be able to iterate the dataset with multiple workers.

## Actual results
Prints with results with `next(iter(multilingual_dataset)) ` and `num_workers=0`  but it prints nothing with `num_workers=4` or any number above 0.

## Environment info
<!-- You can run the command `datasets-cli env` and copy-and-paste its output below. -->
- `datasets` version: 2.0.1.dev0
- `pytorch` version: 1.10.0+cu113

Comments: Same thing occurs when streaming files loaded from disk.

Hi ! Thanks for reporting, could this be related to https://github.com/huggingface/datasets/issues/3950 ?

Currently streaming datasets only works in single process, but we're working on having in work in distributed setups as well :) (EDIT: done)

Hi, thanks for your reply. It seems related :)

Please update `datasets` if you're having this issue. What version are you using ?
Image column is not decoded in map when using with with_transform
State: closed | Author: phihung (NONE)
Labels: name: bug

## Describe the bug
Image column is not _decoded_ in **map** when using with `with_transform`

## Steps to reproduce the bug
```python
from datasets import Image, Dataset

def add_C(batch):
    batch["C"] = batch["A"]
    return batch

ds = Dataset.from_dict({"A": ["image.png"]}).cast_column("A",  Image())
ds = ds.with_transform(lambda x: x)  # <= This line causes the problem
ds = ds.map(add_C, batched=True)
print(ds[0])
```

## Expected results
```
{'C': <PIL.PngImagePlugin.PngImageFile>,  ...}
```

## Actual results
```
{'C': {'bytes': None, 'path': 'image.png'}, ...}
```

If we remove the `with_transform` line, we get the expected result.

## Environment info
- `datasets` version: 2.0.0
- Platform: Mac OSX
- Python version: 3.8.12
- PyArrow version: 7.0.0


Comments: Hi! This behavior stems from this line: https://github.com/huggingface/datasets/blob/799b817d97590ddc97cbd38d07469403e030de8c/src/datasets/arrow_dataset.py#L1919
Basically, the `Image`/`Audio` columns are decoded only if the `format_type` attribute is `None` (`set_format`/`with_format` and `set_transform`/`with_transform` assign a non-`None` value to it) and the  `input_columns` param is not specified (see https://github.com/huggingface/datasets/issues/3756). We will remove these limitations soon.

Improve AutomaticSpeechRecognition task template
State: closed | Author: polinaeterna (CONTRIBUTOR)
Labels: name: enhancement

**Is your feature request related to a problem? Please describe.**
[AutomaticSpeechRecognition task template](https://github.com/huggingface/datasets/blob/master/src/datasets/tasks/automatic_speech_recognition.py) is outdated as it uses path to audiofile as an audio column instead of a Audio feature itself (I guess it's because Audio feature didn't exist at the time this template was created).

**Describe the solution you'd like**
Change audio columns from string path to Audio feature.

> This makes me think we shouldn't advise the use of load_dataset in dataset scripts, since it doesn't guarantee that the cache will work as expected (the cache directory is not set correctly, and the required disk space for downloaded files is not recorded)

@lhoestq, do you think it could be a good idea to add a comment in this script WARNING that using load_dataset in a script is not good practice and that people should avoid using that script as a template to create other scripts? 

good idea ! :)
Fix Faiss custom_index device
State: closed | Author: albertvillanova (MEMBER)

Currently, if both `custom_index` and `device` are passed to `FaissIndex`, `device` is silently ignored.

This PR fixes this by raising a ValueError if both arguments are passed.

Alternatively, the `custom_index` could be transferred to the target `device`.

[image feature] Too many files open error when image feature is returned as a path
State: closed | Author: apsdehal (CONTRIBUTOR)
Labels: name: bug

## Describe the bug

PR in context: #3967. If I load the dataset in this PR (TextVQA), and do a simple list comprehension on the dataset, I get `Too many open files error`. This is happening due to the way we are loading the image feature when a str path is returned from the `_generate_examples`. Specifically at https://github.com/huggingface/datasets/blob/508eb4ab5d52f590baa677b4f64b1cc069139f7b/src/datasets/features/image.py#L110, we are open the file handle to the image but never closing it. This in my understanding is causing the issue.

## Steps to reproduce the bug
Pull the PR locally and run the following code
```python
from datasets import load_dataset

dataset = load_dataset("./datasets/textvqa")["train"]
data = [item for item in dataset]

# Error happens
```

## Expected results

List comprehension should work smoothly

## Actual results

`Too many open files error`

Add tip on how to speed up loading with ImageFolder

This PR does two things:
* adds a tip on how to speed up loading of a large number of files with ImageFolder (motivated by [this issue](https://github.com/huggingface/datasets/issues/3960))
* replaces the current references to the `Dataset` methods in the Image Processing doc with their fully qualified counterparts (to align it with the Audio Processing doc)

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

Thanks for adding that tip! 👍 

For the docs syntax, it might be better if we hide the package name/full path to the class or function and only show the name of it. I think it's easier for users to read the function name (eg,`cast_column`) instead of the full path which can be a bit lengthy for some functions like `datasets.IterableDataset.remove_columns` (and if we like this idea, we can align the rest of the docs on it).

That's also OK, as long as we are consistent.

@lhoestq @albertvillanova @polinaeterna Which one of these two styles do you prefer?

Agree on hiding `datasets` name. Not sure about hiding class name as it's anyway not visible for users if they use `Dataset.cast_column` or  `IterableDataset.cast_column` when working with their datasets. But I agree that the most important thing is to be consistent :)

Good points! :)

I think it'll be good to show the class name since some functions have different parameters. For example, if users click on `IterableDataset.map` and then `Dataset.map`, they'll see different parameters and have to figure out why (which isn't too difficult I guess lol). But showing the class name avoids any confusion upfront.
Fix google drive streaming for small files

Google drive did another change recently, following #3787 #3843 .

In particular Google Drive now returns 403 for GET requests with `confirm=t` when a files doesn't have a virus warning message. I fixed this by passing `confirm=t` if and only if when there is one (i.e. when status code is 200 for HEAD)

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

Actually the CI fails because of this

It looks like we can't have a proper way to test google drive in the CI right now. Though it seems to work locally if you're not banned. I think I'll just disable those tests for now

this fix will not be included?

No we can't do anything except stop using google drive when possible
