Due to license restriction, this dataset needs manual downloading of the original data.

This information is in the dataset card: https://huggingface.co/datasets/timit_asr
> The dataset needs to be downloaded manually from https://catalog.ldc.upenn.edu/LDC93S1

Maybe a better error message for datasets that need manual downloading? @severo 

Maybe we can raise a specific excpetion as done from `load_dataset`...

Yes, ideally something like https://github.com/huggingface/datasets/blob/main/src/datasets/builder.py#L81


The preview is now disabled (and a descriptive warning is displayed) for datasets requiring manual download. See:

datasets generate large arrow file
State: closed
Labels: description: Something isn't working
name: bug

Checking the large file in disk, and found the large cache file in the cifar10 data directory:

![image](https://user-images.githubusercontent.com/18533904/186830449-ba96cdeb-0fe8-4543-994d-2abe7145933f.png)

As we know, the size of cifar10 dataset is ~130MB, but the cache file has almost 30GB size, there may be some problems here.

Comments:
Hi ! The cache files are the results of all the transforms you applied to the dataset using `map` for example.
Did you run a transform that could potentially blow up the size of the dataset ?

@lhoestq,
I don't remember, but I can't imagine what kind of transform may generate data that grow over 200 times in size. 
I think maybe it doesn' matter, it's just cache after all.

add Dataset.from_list
State: closed

As discussed in #4885 

I initially added this bit at the end, thinking filling this field was necessary as it is done in from_dict. 
However, it seems the constructor takes care of filling info when it is empty.
```
if info.features is None:
  info.features = Features(
      {
          col: generate_from_arrow_type(coldata.type)
          for col, coldata in zip(pa_table.column_names, pa_table.columns)
      }
  )
```

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

@albertvillanova it seems tests fail on pyarrow 6, perhaps from_pylist is a v7 method? How do you usually handle these version differences?
Added something that at least works

Create dataset from list of dicts
State: closed
Labels: description: New feature or request
name: enhancement

I often find myself with data from a variety of sources, and a list of dicts is very common among these.
However, converting this to a Dataset is a little awkward, requiring either

```Dataset.from_pandas(pd.DataFrame(formatted_training_data))```
Which can error out on some more exotic values as 2-d arrays for reasons that are not entirely clear
> ArrowInvalid: ('Can only convert 1-dimensional array values', 'Conversion failed for column labels with type object')

Alternatively:
```Dataset.from_dict({k: [s[k] for s in formatted_training_data] for k in  formatted_training_data[0].keys()})```
Which works, but is a little ugly.

**Describe the solution you'd like**
Either `.from_dict` accepting a list of dicts, or a `.from_records` function accepting such.

I am happy to PR this, just wanted to check you are happy to accept this I haven't missed something obvious, and which of the solutions would be prefered.


Comments:
Hi @sanderland, thanks for your enhancement proposal.

I agree with you that this would be useful.

Please note that under the hood, we use PyArrow tables as backend:
- The implementation  of `Dataset.from_dict` uses the PyArrow `Table.from_pydict`

Therefore, I would suggest:
- Implementing `Dataset.from_list` using the PyArrow `Table.from_pylist`

What do you think?
Let's see if other people have other suggestions...

Thanks for the quick and positive reply @albertvillanova! 
`from_list` seems sensible. Have opened a PR so we can discuss details there.

Resolved via #4890.

[not really a bug] `identical_ok` is deprecated in huggingface-hub's `upload_file`
State: closed
Labels: description: Extra attention is needed
name: help wanted

description: Further information is requested
name: question

In the huggingface-hub dependency, the `identical_ok` argument has no effect in `upload_file` (and it will be removed soon)

See

https://github.com/huggingface/huggingface_hub/blob/43499582b19df1ed081a5b2bd7a364e9cacdc91d/src/huggingface_hub/hf_api.py#L2164-L2169

We should remove it.

Maybe the third code sample has an unexpected behavior since it uses the non-default value `identical_ok = False`, but the argument is ignored.

Multiple dataloader memory error
State: open
Labels: description: Something isn't working

For the use of multiple datasets and tasks, we use around more than 200+ dataloaders, then pass it into `dataloader1, dataloader2, ..., dataloader200=accelerate.prepare(dataloader1, dataloader2, ..., dataloader200)`

Hi!

200+ data loaders is a lot. Have you tried to reduce the number of datasets by concatenating/interleaving the ones with the same structure/task (the API is `{concatenate_datasets/interleave_datasets}([dset1, ..., dset_N])`)?

Hi @mariosasko, thank you for your reply. I tried pre-concatenating different datasets into one, but one key need is to keep each batch the same data type. Considering that the concatenate-then-segment operation for prefetched samples may span across different data types after concatenating/interleaving (cuz different data sources are mixed), any solution to remain the same data source for each batch?

@cyk1337 have you found any solutions to it?
@mariosasko I tried with interleave_datasets to sample batches from two large datasets (wikipedia alike) and it results in out-of-memory error during data loading (16gpus, >1TB physical memory). Do you have any idea about it?

adding mafand to datasets

I'm addding the MAFAND dataset by Masakhane based on the paper/repository below:

Paper: https://aclanthology.org/2022.naacl-main.223/
Code: https://github.com/masakhane-io/lafand-mt

Please, help merge this

Everything works except for creating dummy data file

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

Hi @dadelani, thanks for your awesome contribution!!! :heart: 

However, now we are using the Hub to add new datasets, instead of this GitHub repo. 

You could share this dataset under your Hub organization namespace: [Masakhane NLP](https://huggingface.co/masakhane). This way the dataset will be accessible using:
```python
ds = load_dataset("masakhane/mafand")
```

You have the procedure documented in our online docs: 
- [Create a dataset loading script](https://huggingface.co/docs/datasets/dataset_script)
- [Share](https://huggingface.co/docs/datasets/share)

Moreover, datasets shared on the Hub no longer need the dummy data files.

Please, feel free to ping me if you need any further guidance/support.

thank you for the comment. I have moved it to the Hub https://huggingface.co/datasets/masakhane/mafand

Great job, @dadelani!!

Please, note that in the README.md file, the YAML tags should be preceded and followed by three dashes `---`, so that they are properly parsed. See, e.g.: https://raw.githubusercontent.com/huggingface/datasets/main/templates/README.md

Also you could replace the line:
```
# Dataset Card for [Needs More Information]
```
with
```
# Dataset Card for MAFAND-MT
```

Great, thank you for the feedback. I have fixed both issues.
Dataset Viewer issue for MoritzLaurer/multilingual_nli

_No response_

### Description

I've just uploaded a new dataset to the hub and the viewer does not work for some reason, see here: https://huggingface.co/datasets/MoritzLaurer/multilingual_nli

It displays the error: 
```
Status code:   400
Exception:     Status400Error
Message:       The dataset does not exist.
```

Weirdly enough the dataviewer works for an earlier version of the same dataset. The only difference is that it is smaller, but I'm not aware of other changes I have made: https://huggingface.co/datasets/MoritzLaurer/multilingual_nli_test

Do you know why the dataviewer is not working?

Comments:
Thanks for reporting  @MoritzLaurer.

Currently, the dataset preview is working properly: https://huggingface.co/datasets/MoritzLaurer/multilingual_nli

Please note that when a dataset is modified, it might take some time until the preview is completely updated.

@severo might it be worth adding a clearer error message, something like "The preview is updating, please retry later"?

Thanks for your response. You are right, its now working well. I had waited for 30 min or so and refreshed several times and thought there was some other error. Yeah, a different error message sounds like a good idea to avoid confusion. 

I'm closing this issue then.

> @severo might it be worth adding a clearer error message, something like "The preview is updating, please retry later"?

Yes, it's a known issue, and we're about to ship a better version
Allow pathlib PoxisPath in Dataset.read_json
State: open
Labels: description: New feature or request
name: enhancement

**Is your feature request related to a problem? Please describe.**
```
from pathlib import Path
from datasets import Dataset
ds = Dataset.read_json(Path('data.json'))
```
causes an error
```
AttributeError: 'PosixPath' object has no attribute 'decode'
```

**Describe the solution you'd like**

It should be able to accept PosixPath and read the json from inside.

Comments:
This same error will occur using `ds = datasets.load_dataset('json', data_files=['test.jsonl'])`

@cccntu I want to make a quick fix for this, but I am struggling to find where the json dataset builder is. Do you know?

@vvvm23 I think you mean think:
```python
ds = datasets.load_dataset('json', data_files=[Path('test.jsonl')])
```
And the place you want to modify is here:
```
utils/file_utils.py:64, in is_remote_url(url_or_filename)
     63 def is_remote_url(url_or_filename: str) -> bool:
---> 64     parsed = urlparse(url_or_filename)
     65     return parsed.scheme in ("http", "https", "s3", "gs", "hdfs", "ftp")
```

Probably just need to check first if `url_or_filename` is [PathLike](https://docs.python.org/3/library/os.html#os.PathLike) and return False early.

Btw, I tried installing from main, and ran my code above and got a different error. Probably because the API have changed.
`AttributeError: module 'datasets' has no attribute 'read_json'`


> @vvvm23 I think you mean think:

You are correct, thanks!

> Probably just need to check first if url_or_filename is [PathLike](https://docs.python.org/3/library/os.html#os.PathLike) and return False early.

Is PathLike sufficient, or should I check the file exists here? Or is that handled later?

I think here we just want to avoid passing Path to urlparse. A simpler solution is to add a str() call and convert the input to string before passing to the next step. No need to check anything.

Above PR should do your first suggestion. Hope that works for you, as I am going on holiday and won't be able to change much :wink: 

I just came across this problem with `DatasetDict.from_parquet()`. The error still seems to originate from the same place:
```
  File "/usr/local/lib/python3.12/dist-packages/datasets/utils/file_utils.py", line 88, in is_relative_path
    return urlparse(url_or_filename).scheme == "" and not os.path.isabs(url_or_filename)
           ^^^^^^^^^^^^^^^^^^^^^^^^^
```
The PR looks like it would still solve everything. Is there a reason this got delayed?

Using disk for memory with the method `from_dict`
State: open
Labels: description: New feature or request
name: enhancement

**Is your feature request related to a problem? Please describe.**
I start with an empty dataset. In a loop, at each iteration, I create a new dataset with the method `from_dict` (based on some data I load) and I concatenate this new dataset with the one at the previous iteration. After some iterations, I have an OOM error.

**Describe the solution you'd like**
The method `from_dict` loads the data in RAM. It could be good to add an option to use the disk instead.

**Describe alternatives you've considered**
To solve the problem, I have to do an intermediate step where I save the new datasets at each iteration with `save_to_disk`. Once it's done, I open them all and concatenate them.


Comments:
This issue was also causing an OOM in @nateraw 's workflow and shows again that behavior is confusing - we should definitely switch to using the disk IMO
