Issue: TypeError when loading from GCP bucket
State: closed
Author: bilelomrani1

### Describe the bug

Loading a dataset from a GCP bucket raises a type error. This bug was introduced recently (either in 2.14 or 2.14.1), and appeared during a migration from 2.13.1.

### Steps to reproduce the bug

Load any file from a GCP bucket:

```python
import datasets

datasets.load_dataset("json", data_files=["gs://..."])
```

The following exception is raised:

```python
Traceback (most recent call last):
...
packages/datasets/data_files.py", line 335, in resolve_pattern
    protocol_prefix = fs.protocol + "://" if fs.protocol != "file" else ""
TypeError: can only concatenate tuple (not "str") to tuple
```

With a `GoogleFileSystem`, the attribute `fs.protocol` is a tuple `('gs', 'gcs')` and hence cannot be concatenated with a string.


### Expected behavior

The file should be loaded without exception.

### Environment info

- `datasets` version: 2.14.1
- Platform: macOS-13.2.1-x86_64-i386-64bit
- Python version: 3.10.12
- Huggingface_hub version: 0.16.4
- PyArrow version: 12.0.1
- Pandas version: 2.0.3

We have fixed it. We are planning to do a patch release today.
Issue: Dataset.get_nearest_examples does not return all feature values for the k most similar datapoints - side effect of Dataset.set_format
State: closed
Author: aschoenauer-sebag

### Describe the bug

Hi team!

I observe that there seems to be a side effect of `Dataset.set_format`: after setting a format and creating a FAISS index, the method `get_nearest_examples` from the `Dataset` class, fails to retrieve anything else but the embeddings themselves - not super useful. This is not the case if not using the `set_format` method: you can also retrieve any other feature value, such as an index/id/etc.

Are you able to reproduce what I observe?

### Steps to reproduce the bug

```python

from datasets import Dataset
import numpy as np

foo = {'vectors': np.random.random((100,1024)), 'ids': [str(u) for u in range(100)]}
foo = Dataset.from_dict(foo)
foo.set_format('numpy', ['vectors'])
foo.add_faiss_index('vectors')
new_vector = np.random.random(1024)
scores, res = foo.get_nearest_examples('vectors', new_vector, k=3)
```
This will return, for the resulting most similar vectors to `new_vector` - in particular it will not return the `ids` feature:
```
{'vectors': array([[random values ...]])}
```

### Expected behavior

The expected behavior happens when the `set_format` method is not called:
```python

from datasets import Dataset
import numpy as np

foo = {'vectors': np.random.random((100,1024)), 'ids': [str(u) for u in range(100)]}
foo = Dataset.from_dict(foo)
# foo.set_format('numpy', ['vectors'])
foo.add_faiss_index('vectors')
new_vector = np.random.random(1024)
scores, res = foo.get_nearest_examples('vectors', new_vector, k=3)
```
This *will*  return the `ids` of the similar vectors - with unfortunately a list of lists in lieu of the array I think for caching reasons - read it elsewhere
```
{'vectors': [[random values on multiple lines...]], 'ids': ['x', 'y', 'z']}
```

### Environment info

- `datasets` version: 2.12.0
- Platform: Linux-5.4.0-155-generic-x86_64-with-glibc2.31
- Python version: 3.10.6
- Huggingface_hub version: 0.15.1
- PyArrow version: 11.0.0
- Pandas version: 1.5.3


Comments:
Actually, my bad -- specifying
```python
foo.set_format('numpy', ['vectors'], output_all_columns=True)
```
fixes it.
Issue: FilesIterable skips all the files after a hidden file
State: closed
Author: dkrivosic

### Describe the bug

When initializing `FilesIterable` with a list of file paths using `FilesIterable.from_paths`, it will discard all the files after a hidden file.
The problem is in [this line](https://github.com/huggingface/datasets/blob/88896a7b28610ace95e444b94f9a4bc332cc1ee3/src/datasets/download/download_manager.py#L233C26-L233C26) where `return` should be replaced by `continue`. 

### Steps to reproduce the bug

https://colab.research.google.com/drive/1SQlxs4y_LSo1Q89KnFoYDSyyKEISun_J#scrollTo=93K4_blkW-8-

### Expected behavior

The script should print all the files except the hidden one.

### Environment info

- `datasets` version: 2.14.1
- Platform: Linux-5.15.109+-x86_64-with-glibc2.35
- Python version: 3.10.6

Issue: Loading local data files initiates web requests
State: closed
Author: lytning98

As documented in the [official docs](https://huggingface.co/docs/datasets/v2.14.0/en/package_reference/loading_methods#datasets.load_dataset.example-2), I tried to load datasets from local files by
```python
# Load a JSON file
from datasets import load_dataset
ds = load_dataset('json', data_files='path/to/local/my_dataset.json')
```
But this failed on a web request because I'm executing the script on a machine without Internet access. Stacktrace shows
```
in PackagedDatasetModuleFactory.__init__(self, name, data_dir, data_files, download_config, download_mode)
    940 self.download_config = download_config
    941 self.download_mode = download_mode
--> 942 increase_load_count(name, resource_type="dataset")
```
I've read from the source code that this can be fixed by setting environment variable to run in offline mode. I'm just wondering that is this an expected behaviour that even loading a LOCAL JSON file requires Internet access by default? And what's the point of requesting to `increase_load_count` on some server when loading just LOCAL data files?

Issue: Support `fsspec` in `Dataset.to_<format>` methods
State: closed
Author: mariosasko

Supporting this should be fairly easy.

Requested on the forum [here](https://discuss.huggingface.co/t/how-can-i-convert-a-loaded-dataset-in-to-a-parquet-file-and-save-it-to-the-s3/48353).

Comments:
Hi @mariosasko unless someone's already working on it, I guess I can tackle it!

Hi! Sure, feel free to tackle this.

#self-assign

I'm assuming this should just cover `to_csv`, `to_parquet`, and `to_json`, right? As `to_list` and `to_dict` just return Python objects, `to_pandas` returns a `pandas.DataFrame` and `to_sql` just inserts into a SQL DB, is that right?

Fixed by #6096.
Issue: Changing pixel values of images in the Winoground dataset
State: open
Author: ZitengWangNYU

Hi, as I followed the instructions, with lasted "datasets" version:
"
from datasets import load_dataset
examples = load_dataset('facebook/winoground', use_auth_token=<YOUR USER ACCESS TOKEN>)
"
I got slightly different datasets in colab and in my hpc environment. Specifically, the pixel values of images are slightly different. 
I thought it was due to the package version difference, but today's morning I found out that my winoground dataset in colab became the same with the one in my hpc environment. The dataset in colab can produce the correct result but now it is gone as well. 

Can you help me with this? What causes the datasets to have the wrong pixel values?

Issue: resume_download with streaming=True
State: closed
Author: NicolasMICAUX

### Describe the bug

I used:
```
dataset = load_dataset(
    "oscar-corpus/OSCAR-2201",
    token=True,
    language="fr",
    streaming=True,
    split="train"
)
```
Unfortunately, the server had a problem during the training process. I saved the step my training stopped at.
But how can I resume download from step 1_000_´000 without re-streaming all the first 1 million docs of the dataset?

`download_config=DownloadConfig(resume_download=True)` seems to not work with streaming=True.

### Steps to reproduce the bug

```
from datasets import load_dataset, DownloadConfig
dataset = load_dataset(
    "oscar-corpus/OSCAR-2201",
    token=True,
    language="fr",
    streaming=True,  # optional
    split="train",
    download_config=DownloadConfig(resume_download=True)
)
# interupt the run and try to relaunch it => this restart from scratch
```

### Expected behavior

I would expect a parameter to start streaming from a given index in the dataset.

### Environment info

- `datasets` version: 2.14.0
- Platform: Linux-5.19.0-45-generic-x86_64-with-glibc2.29
- Python version: 3.8.10
- Huggingface_hub version: 0.15.1
- PyArrow version: 12.0.1
- Pandas version: 2.0.0

Comments:
Currently, it's not possible to efficiently resume streaming after an error. Eventually, we plan to support this for Parquet (see https://github.com/huggingface/datasets/issues/5380). 

Ok thank you for your answer

Hello, 

I use the above function to deal with my local data set, but I am very surprised that the speed at which I generate example is very different. When I start a training task, **sometimes 1000examples/s, sometimes only 10examples/s.**

![image](https://github.com/huggingface/datasets/assets/46072190/cdc17661-8267-4fd8-b30c-b74d505efd9b)

I'm not saying that speed is changing all the time. I mean, the reading speed is different in different training, which will cause me to start training over and over again until the speed of this generation of examples is normal.


Comments:
Hi!

It's hard to explain this behavior without more information. Can you profile the slower version with the following code
```python
import cProfile, pstats
from datasets import load_dataset

with cProfile.Profile() as profiler:
    ds = load_dataset(...)

stats = pstats.Stats(profiler).sort_stats("cumtime")
stats.print_stats()
```
and share the output?

Issue: Multi-processed `Dataset.map` slows down a lot when `import torch`
State: closed
Author: ShinoharaHare

### Describe the bug

When using `Dataset.map` with `num_proc > 1`, the speed slows down much if I add `import torch` to the start of the script even though I don't use it.

I'm not sure if it's `torch` only or if any other package that is "large" will also cause the same result.
BTW, `import lightning` also slows it down.

Below are the progress bars of `Dataset.map`, the only difference between them is with or without `import torch`, but the speed varies by 6-7 times.

- without `import torch` ![image](https://github.com/huggingface/datasets/assets/47121592/0233055a-ced4-424a-9f0f-32a2afd802c2)
- with `import torch` ![image](https://github.com/huggingface/datasets/assets/47121592/463eafb7-b81e-4eb9-91ca-fd7fe20f3d59)


### Steps to reproduce the bug

Below is the code I used, but I don't think the dataset and the mapping function have much to do with the phenomenon.

```python3
from datasets import load_from_disk, disable_caching
from transformers import AutoTokenizer
# import torch
# import lightning

def rearrange_datapoints(
    batch,
    tokenizer,
    sequence_length,
):
    datapoints = []
    
    input_ids = []
    for x in batch['input_ids']:
        input_ids += x
        while len(input_ids) >= sequence_length:
            datapoint = input_ids[:sequence_length]
            datapoints.append(datapoint)
            input_ids[:sequence_length] = []

    if input_ids:
        paddings = [-1] * (sequence_length - len(input_ids))
        datapoint = paddings + input_ids if tokenizer.padding_side == 'left' else input_ids + paddings
        datapoints.append(datapoint)
    
    batch['input_ids'] = datapoints
    return batch


if __name__ == '__main__':
    disable_caching()

    tokenizer = AutoTokenizer.from_pretrained('...', use_fast=False)
    dataset = load_from_disk('...')
    
    dataset = dataset.map(
        rearrange_datapoints,
        fn_kwargs=dict(
            tokenizer=tokenizer,
            sequence_length=2048,
        ),
        batched=True,
        num_proc=8,
    )

```

### Expected behavior

The multi-processed `Dataset.map` function speed between with and without `import torch` should be the same.

### Environment info

- `datasets` version: 2.13.1
- Platform: Linux-3.10.0-1127.el7.x86_64-x86_64-with-glibc2.31

Issue: Change package name from "datasets" to something less generic
State: closed
Author: jack-jjm

### Feature request

I'm repeatedly finding myself in situations where I want to have a package called `datasets.py` or `evaluate.py` in my code and can't because those names are being taken up by Huggingface packages. While I can understand how (even from the user's perspective) it's aesthetically pleasing to have nice terse library names, ultimately a library hogging simple names like this is something I find short-sighted, impractical and at my most irritable, frankly rude.

My preference would be a pattern like what you get with all the other big libraries like numpy or pandas:

```
import huggingface as hf
# hf.transformers, hf.datasets, hf.evaluate
```

or things like

```
import huggingface.transformers as tf
# tf.load_model(), etc
```

If this isn't possible for some technical reason, at least just call the packages something like `hf_transformers` and so on.

I realize this is a very big change that's probably been discussed internally already, but I'm making this issue and sister issues on each huggingface project just to start the conversation and begin tracking community feeling on the matter, since I suspect I'm not the only one who feels like this.

Sorry if this has been requested already on this issue tracker, I couldn't find anything looking for terms like "package name".

Sister issues:
- [transformers](https://github.com/huggingface/transformers/issues/24934)
- **datasets**
- [evaluate](https://github.com/huggingface/evaluate/issues/476)

### Motivation

Not taking up package names the user is likely to want to use.

### Your contribution

No - more a matter of internal discussion among core library authors.

Comments:
This would break a lot of existing code, so we can't really do this.

I encountered this issue while working on a large project with 6+ years history. We have a submodule named datasets in the backend, and face a big challenge incorporating huggingface datasets into the project, especially considering django app renaming and other issues.
It would be nice if the authors at least provide a recipe on how to avoid name conflict in this situation.
Issue: Skipping shard in the remote repo and resume upload
State: closed
Author: rs9000

### Describe the bug

For some reason when I try to resume the upload of my dataset, it is very slow to reach the index of the shard from which to resume the uploading.

From my understanding, the problem is in this part of the code:

arrow_dataset.py
```python
for index, shard in logging.tqdm(
            enumerate(itertools.chain([first_shard], shards_iter)),
            desc="Pushing dataset shards to the dataset hub",
            total=num_shards,
            disable=not logging.is_progress_bar_enabled(),
        ):
            shard_path_in_repo = path_in_repo(index, shard)
            # Upload a shard only if it doesn't already exist in the repository
            if shard_path_in_repo not in data_files:
```

In particular, iterating the generator is slow during the call:
```python
self._select_contiguous(start, length, new_fingerprint=new_fingerprint)
```

I wonder if it is possible to avoid calling this function for shards that are already uploaded and just start from the correct shard index.

### Steps to reproduce the bug

1. Start the upload
```python
dataset = load_dataset("imagefolder", data_dir=DATA_DIR, split="train", drop_labels=True)    
dataset.push_to_hub("repo/name")
```
2. Stop and restart the upload after hundreds of shards

### Expected behavior

Skip the uploaded shards faster.

### Environment info

- `datasets` version: 2.5.1
- Platform: Linux-4.18.0-193.el8.x86_64-x86_64-with-glibc2.17
- Python version: 3.8.16
- PyArrow version: 12.0.1
- Pandas version: 2.0.2


Comments:
Hi! `_select_contiguous` fetches a (zero-copy) slice of the dataset's Arrow table to build a shard, so I don't think this part is the problem. To me, the issue seems to be the step where we embed external image files' bytes (a lot of file reads). You can use `.map` with multiprocessing to perform this step before `push_to_hub` in a faster manner and cache it to disk:
```python
from datasets.table import embed_table_storage
# load_dataset(...)
format = dataset.format
dataset = dataset.with_format("arrow")
dataset = dataset.map(embed_table_storage, batched=True)
dataset = dataset.with_format(**format)
# push_to_hub(...)
```

(In Datasets 3.0, these external bytes will be written to an Arrow file when generating a dataset to avoid this "embed" step)

Hi, thanks, this solution saves some time.
But can't we avoid embedding all external image files bytes with each push, skipping the images that have already been pushed into the repo?

Edit: Ok I missed the part of cache it manually on the disk the first time, this solves the problem. Thank you
