Minimartzz/github-issues huggingface dataset:
Manual downloads should count as downloads
State: open
Labels: description: New feature or request
name: enhancement

### Feature request

I would like to request that manual downloads of data files from Hugging Face dataset repositories count as downloads of a dataset. According to the documentation for the Hugging Face Hub, that is currently not the case: https://huggingface.co/docs/hub/en/datasets-download-stats

### Motivation

This would ensure that downloads are accurately reported to end users.

### Your contribution

N/A

Comments:
We're unlikely to add more features/support for datasets with python loading scripts, which include datasets with manual download. Sorry for the inconvenience

`Dataset.with_format` behaves inconsistently with documentation
State: closed
Labels: description: Improvements or additions to documentation
name: documentation

### Describe the bug

The actual behavior of the interface `Dataset.with_format` is inconsistent with the documentation.
https://huggingface.co/docs/datasets/use_with_pytorch#n-dimensional-arrays
https://huggingface.co/docs/datasets/v2.19.0/en/use_with_tensorflow#n-dimensional-arrays

> If your dataset consists of N-dimensional arrays, you will see that by default they are considered as nested lists.
> In particular, a PyTorch formatted dataset outputs nested lists instead of a single tensor.
> A TensorFlow formatted dataset outputs a RaggedTensor instead of a single tensor.

But I get a single tensor by default, which is  inconsistent with the description.

Actually the current behavior seems more reasonable to me. Therefore, the document needs to be modified.

### Steps to reproduce the bug

```python
>>> from datasets import Dataset
>>> data = [[[1, 2],[3, 4]],[[5, 6],[7, 8]]]
>>> ds = Dataset.from_dict({"data": data})
>>> ds = ds.with_format("torch")
>>> ds[0]
{'data': tensor([[1, 2],
        [3, 4]])}
>>> ds = ds.with_format("tf")
>>> ds[0]
{'data': <tf.Tensor: shape=(2, 2), dtype=int64, numpy=
array([[1, 2],
       [3, 4]])>}
```

### Expected behavior

```python
>>> from datasets import Dataset
>>> data = [[[1, 2],[3, 4]],[[5, 6],[7, 8]]]
>>> ds = Dataset.from_dict({"data": data})
>>> ds = ds.with_format("torch")
>>> ds[0]
{'data': [tensor([1, 2]), tensor([3, 4])]}
>>> ds = ds.with_format("tf")
>>> ds[0]
{'data': <tf.RaggedTensor [[1, 2], [3, 4]]>}
```

### Environment info

load_dataset error
State: closed

### Describe the bug

Why does the program get stuck when I use load_dataset method, and it still gets stuck after loading for several hours? In fact, my json file is only 21m, and I can load it in one go using open('', 'r').

### Steps to reproduce the bug

1. pip install datasets==2.19.2
2. from datasets import Dataset, DatasetDict, NamedSplit, Split, load_dataset
3. data = load_dataset('json', data_files='train.json')

### Expected behavior

It is able to load my json correctly

### Environment info

datasets==2.19.2

Comments:
Hi, @lion-ops.

In our Continuous Integration we have many tests on loading JSON files and all of them work properly.

Could you please share your "train.json" file, so that we can try to reproduce the issue you have?

Thank you for your reply. I can load it normally in another server. Is it possible that the disk of my server is a network disk in the LAN, so it will be downloaded from the LAN and get stuck?
to_tf_dataset: Visible devices cannot be modified after being initialized
State: open

### Describe the bug

When trying to use to_tf_dataset with a custom data_loader collate_fn when I use parallelism I am met with the following error as many times as number of workers there were in ``num_workers``.

  File "/opt/miniconda/envs/env/lib/python3.11/site-packages/multiprocess/process.py", line 314, in _bootstrap

RuntimeError: Visible devices cannot be modified after being initialized

### Steps to reproduce the bug

1. Download a dataset using HuggingFace load_dataset
2. Define a function that transforms the data in some way to be used in the collate_fn argument
3. Provide a ``batch_size`` and ``num_workers`` value in the ``to_tf_dataset`` function
4. Either retrieve directly or use tfds benchmark to test the dataset

``` python
from datasets import load_datasets
import tensorflow_datasets as tfds
from keras_cv.layers import Resizing

def data_loader(examples):
      x = Resizing(examples[0]['image'], 256, 256, crop_to_aspect_ratio=True)
      return {X[0]: x}

ds = load_datasets("logasja/FDF", split="test")

ds = ds.to_tf_dataset(collate_fn=data_loader, batch_size=16, num_workers=2)

tfds.benchmark(ds)
```

### Expected behavior

Use multiple processes to apply transformations from the collate_fn to the tf dataset on the CPU.

### Environment info

Enable Sharding to Equal Sized Shards
State: open
Labels: description: New feature or request
name: enhancement

### Feature request

Add an option when sharding a dataset to have all shards the same size. Will be good to provide both an option of duplication, and by truncation.

### Motivation

Currently the behavior of sharding is "If n % i == l, then the first l shards will have length (n // i) + 1, and the remaining shards will have length (n // i).". However, when using FSDP we want the shards to have the same size. This requires the user to manually handle this situation, but it will be nice if we had an option to shard the dataset into equally sized shards. 

### Your contribution

For now just a PR. I can also add code that does what is needed, but probably not efficient.
Shard to equal size by duplication:
```
remainder = len(dataset) % num_shards
num_missing_examples = num_shards - remainder
duplicated = dataset.select(list(range(num_missing_examples)))
dataset = concatenate_datasets([dataset, duplicated])
shard = dataset.shard(num_shards, shard_idx)
```
Or by truncation:
```
shard = dataset.shard(num_shards, shard_idx)
num_examples_per_shard = len(dataset) // num_shards
shard = shard.select(list(range(num_examples_per_shard)))
```

save_to_disk() freezes when saving on s3 bucket with multiprocessing
State: open

### Describe the bug

I'm trying to save a `Dataset` using the `save_to_disk()` function with:
- `num_proc > 1`
- `dataset_path` being a s3 bucket path e.g. "s3://{bucket_name}/{dataset_folder}/"

The hf progress bar shows up but the saving does not seem to start. 
When using one processor only (`num_proc=1`), everything works fine.
When saving the dataset on local disk (as opposed to s3 bucket) with `num_proc > 1`, everything works fine.

Thank you for your help! :)

### Steps to reproduce the bug

I tried without any storage options:

```
from datasets import load_dataset

sandbox_ds = load_dataset("openai_humaneval")
sandbox_ds["test"].save_to_disk(
    "s3://bucket-name/test_multiprocessing_saving/",
    num_proc=4,
)
```


and with the specific s3fs storage options: 
```
from datasets import load_dataset
from s3fs import S3FileSystem

def get_s3fs():
    return S3FileSystem()

sandbox_ds = load_dataset("openai_humaneval")
sandbox_ds["test"].save_to_disk(
    "s3://bucket-name/test_multiprocessing_saving/",
    num_proc=4,
    storage_options=get_s3fs().storage_options, # also tried: storage_options=S3FileSystem().storage_options
)
```

I'm guessing I might use `storage_options` parameter wrongly, but I didn't find anything online that made it work.

**NB**: Behavior is the same when trying to save the whole `DatasetDict`.

### Expected behavior

Progress bar fills in and saving is carried out.

### Environment info

Support for pathlib.Path in datasets 2.19.0
State: open

### Describe the bug

After the recent update of `datasets`, Dataset.save_to_disk does not accept a pathlib.Path anymore. It was supported in 2.18.0 and previous versions. Is this intentional? Was it supported before only because of a Python dusk-typing miracle?

### Steps to reproduce the bug

```
from datasets import Dataset
import pathlib

path = pathlib.Path("./my_out_path")
Dataset.from_dict(
    {"text": ["hello world"], "label": [777], "split": ["train"]}
.save_to_disk(path)
```
This results in an error when using datasets 2.19:
```

  File "<stdin>", line 3, in <module>
  File "/Users/jb/scratch/venv/lib/python3.11/site-packages/datasets/arrow_dataset.py", line 1515, in save_to_disk

Converting to str works, however.

Avoid downloading the whole dataset when only README.me has been touched on hub.
State: open
Labels: description: New feature or request
name: enhancement

### Feature request

`datasets.load_dataset()` triggers a new download of the **whole dataset** when the README.md file has been touched on huggingface hub, even if data files / parquet files are the exact same.

I think the current behaviour of the load_dataset function is triggered whenever a change of the hash of latest commit on huggingface hub, but  is there a clever way to only download again the dataset **if and only if** data is modified ?  

### Motivation

The current behaviour is a waste of network bandwidth / disk space / research time.

### Your contribution

I don't have time to submit a PR, but I hope a simple solution will emerge from this issue !

Caching map result of DatasetDict.

Hi!

I'm currenty using the map function to tokenize a somewhat large dataset, so I need to use the cache to save ~25 mins.

Changing num_proc incduces the recomputation of the map, I'm not sure why and if this is excepted behavior? 

here it says, that cached files are loaded sequentially:

Comments:
Has to do with sharding as far as I am aware, num_proc splits the dataset in shards and each process picks up a shard.

@dimidagd why wouldn't you redistribute the processes (e.g. param_num_process to sequentially fill fingerprint_num_process) to make things work out? 

Perhaps I'm missing something important.

I assume data has to be split between the processes somehow, and the decision to split it to num_processes shards is very convenient :). As I understand, the idea behind individual shard caching is being able to recover part of the processing if one of the processes fails. It would make sense to do a hierarchical cache checking though, where irregardless of the amount of processes, there is a check on whether the entire .map result has been cached or not (basically num_proc=1). Downside is more disk space used to cache both the shards and the entire dataset.
