Dataset scripts are no longer supported, but found superb.py

### Describe the bug

Hello,

I'm trying to follow the [Hugging Face Pipelines tutorial](https://huggingface.co/docs/transformers/main_classes/pipelines) but the tutorial seems to work only on old datasets versions.

I then get the error :

```

```

NB : I tried to replace "superb" by  "anton-l/superb_demo" but I get a 'torchcodec' importing error. Maybe I misunderstood something.

### Steps to reproduce the bug

```
import datasets
from transformers import pipeline
from transformers.pipelines.pt_utils import KeyDataset
from tqdm.auto import tqdm

pipe = pipeline("automatic-speech-recognition", model="facebook/wav2vec2-base-960h", device=0)
dataset = datasets.load_dataset("superb", name="asr", split="test")

# KeyDataset (only *pt*) will simply return the item in the dict returned by the dataset item
# as we're not interested in the *target* part of the dataset. For sentence pair use KeyPairDataset
for out in tqdm(pipe(KeyDataset(dataset, "file"))):
    print(out)
    # {"text": "NUMBER TEN FRESH NELLY IS WAITING ON YOU GOOD NIGHT HUSBAND"}
    # {"text": ....}
    # ....
```

Comments:
I got a pretty similar issue when I try to load bigbio/neurotrial_ner dataset. 
`Dataset scripts are no longer supported, but found neurotrial_ner.py`

Same here. I was running this tutorial and got a similar error: https://github.com/openai/whisper/discussions/654 (I'm a first-time transformers library user)

RuntimeError: Dataset scripts are no longer supported, but found librispeech_asr.py

What am I supposed to do at this point?

Thanks

hey I got the same error and I have tried to downgrade version to 3.6.0 and it works.
`pip install datasets==3.6.0`

Thank you very much @Tin-viAct . That indeed did the trick for me :) 
Now the code continue its normal flow 

Thanks @Tin-viAct, Works!

I converted [openslr/librispeech_asr](https://huggingface.co/datasets/openslr/librispeech_asr) to Parquet - thanks for reporting.

It's now compatible with `datasets` 4.0  !

I'll try to ping the authors of the other datasets like [s3prl/superb](https://huggingface.co/datasets/s3prl/superb) and [espnet/yodas2](https://huggingface.co/datasets/espnet/yodas2)

How come a breaking change was allowed and now requires extra work from individual authors for things to be usable? 

https://en.wikipedia.org/wiki/Backward_compatibility

We follow semantic versioning so that breaking changes only occur in major releases. Also note that dataset scripts have been legacy for some time now, with a message on the dataset pages to ask authors to update their datasets.

It's ok to ping older versions of `datasets`, but imo a few remaining datasets need to be converted since they are valuable to the community.

I was facing the same issue with a not so familiar dataset in hugging hub . downgrading the datasets version worked ❤️. Thank you @Tin-viAct .

Thank you so much, @Tin-viAct ! I’ve been struggling with this issue for about 3 hours, and your suggestion to downgrade datasets worked perfectly. I really appreciate the help—you saved me!

> hey I got the same error and I have tried to downgrade version to 3.6.0 and it works. `pip install datasets==3.6.0`

Thank you so much! I was following the [quickstart](https://huggingface.co/docs/datasets/quickstart) and the very first sample fails. Not a good way to get started....

> hey I got the same error and I have tried to downgrade version to 3.6.0 and it works. `pip install datasets==3.6.0`
thank you! I get it.


I updated `hotpot_qa` and pinged the PolyAI folks to update the dataset used in the quickstart as well: https://huggingface.co/datasets/PolyAI/minds14/discussions/35
edit: merged !
edit2: quickstart dataset is also fixed !

[LegalBench](https://huggingface.co/datasets/nguha/legalbench) is downloaded 10k times a month and is now broken. Would be great to have this fixed.

I opened a PR to convert LegalBench to Parquet and reached out to the author: https://huggingface.co/datasets/nguha/legalbench/discussions/34

Thank you very much @Tin-viAct! I’d been looking everywhere for a fix, and your reply saved me :)

Tried downgrading the datasets version. But the problem with this is that it had led to compatibility issues and other breaking changes and more errors on other parts of my code 

I opened a few more PRs and reached out to the authors:
- https://huggingface.co/datasets/Skylion007/openwebtext/discussions/22 merged ! ✅ 
- https://huggingface.co/datasets/stas/openwebtext-10k/discussions/2

Btw if you want to open a PR to a dataset to convert it to Parquet here is the command:

```
uv run --with "datasets==3.6.0" datasets-cli convert_to_parquet <username/dataset-name> --trust_remote_code
```

(just replace the `<username/dataset-name>` with the dataset repository name)

The `datasets.load_dataset(<username/dataset-name>, revision='refs/convert/parquet')` method can also be used to download converted branches.

Hello,
I have a similar message: "RuntimeError: Dataset scripts are no longer supported, but found code_search_net.py" while following the LLM Course (https://huggingface.co/learn/llm-course/chapter6/2). 

Downgrading via !pip install datasets==3.6.0 works as a workaround.

@lhoestq I tried to update the dataset, but run into an exception, any suggestions on how to solve it? Thanks!

This syntax works with the new version. Here I am trying to download the protein-ligand binding affinity dataset created by jglaser/binding_affinity and hosted on hugging face

from datasets import load_dataset
dataset = load_dataset("parquet", data_files="hf://datasets/jglaser/binding_affinity/data/all.parquet")
df = dataset['train'].to_pandas()
print(f"No, of entries: {len(df)}")

Same for xsum.py

I just opened https://huggingface.co/datasets/EdinburghNLP/xsum/discussions/9 to fix the xsum dataset :)

I used this command:

```
uv run --with datasets==3.6.0 convert_to_parquet EdinburghNLP/xsum --trust_remote_cote
```

edit: merged ! ✅ 

Same for `facebook/voxpopuli` and `google/fleurs` :)

PR is here for `facebook/voxpopuli` :) https://huggingface.co/datasets/facebook/voxpopuli/discussions/16

There is one already opened for `google/fleurs` as well, but it seems incomplete, let me open a PR with a full conversion.
I'm also trying to do superb, gigaspeech and spgispeech

Conversion for `s3prl/superb` is ready here as well: https://huggingface.co/datasets/s3prl/superb/discussions/11
edit: merged ! ✅ 

!pip install datasets==3.6.0 worked for me, but I think this is just a temporary fix. I am sure restricting the dataset to the 3.6.0 version will result in compatibility issues in the future.

This issue seems to be affecting a lot of datasets, what will be the lasting solution to this?

The vast majority of datasets have been converted already. But please share which datasets are still impacted @bornofdata

I just had encountered this problem in `allenai/peS2o`. Thanks for your hard works on this, @lhoestq!

@lhoestq the code_search_net dataset. Thank you for looking into this.
I had to install datasets==3.6.0 to make that work.

Screenshot and code snippet attached below

```
raw_datasets = load_dataset(
    "code_search_net", 
    "python", 
    trust_remote_code=True
)

raw_datasets
```

Ok, sharing my HF Jobs commands to convert them here so you can also run it yourself if you encounter more datasets with this issue:

```bash
>>> hf jobs uv run --flavor cpu-performance --timeout 4d -s HF_TOKEN --with "datasets @ git+https://github.com/huggingface/datasets@large_convert_to_parquet" datasets-cli convert_to_parquet allenai/peS2o --trust_remote_code
>>> hf jobs uv run --flavor cpu-performance --timeout 4d -s HF_TOKEN --with "datasets @ git+https://github.com/huggingface/datasets@large_convert_to_parquet" datasets-cli convert_to_parquet code-search-net/code_search_net --trust_remote_code
```

(with HF Jobs you can run `uv` commands on HF infra, more info in the [docs](https://huggingface.co/docs/hub/en/jobs-overview))

Thank you for sharing @lhoestq. Appreciate it.

@lhoestq Hi, thanks for your help.

The [Amazon Reviews 2023](https://huggingface.co/datasets/McAuley-Lab/Amazon-Reviews-2023) dataset also has this problem. It would be great if you could make an effort to have it updated.

Appreciate your work!

just opened a PR here: https://huggingface.co/datasets/McAuley-Lab/Amazon-Reviews-2023/discussions/27

@lhoestq  https://huggingface.co/datasets/csebuetnlp/xlsum

I opened a PR here for xlsum: https://huggingface.co/datasets/csebuetnlp/xlsum/discussions/7

here is the command I ran using HF Jobs. In the future I'd like people to run it on their end if possible 🙏
