Pushing a large dataset on the hub consistently hangs
### Describe the bug

Once I have locally built a large dataset that I want to push to hub, I use the recommended approach of .push_to_hub to get the dataset on the hub, and after pushing a few shards, it consistently hangs. This has happened over 40 times over the past week, and despite my best efforts to try and catch this happening and kill a process and restart, it seems to be extremely time wasting -- so I came to you to report this and to seek help. 

I already tried installing hf_transfer, but it doesn't support Byte file uploads so I uninstalled it.

### Reproduction

```python
import multiprocessing as mp
import pathlib
from math import ceil

import datasets
import numpy as np
from tqdm.auto import tqdm

from tali.data.data import select_subtitles_between_timestamps
from tali.utils import load_json

tali_dataset_dir = "/data/"

if __name__ == "__main__":
    full_dataset = datasets.load_dataset(
        "Antreas/TALI", num_proc=mp.cpu_count(), cache_dir=tali_dataset_dir
    )

    def data_generator(set_name, percentage: float = 1.0):
        dataset = full_dataset[set_name]

        for item in tqdm(dataset):
            video_list = item["youtube_content_video"]
            video_list = np.random.choice(
                video_list, int(ceil(len(video_list) * percentage))
            )
            if len(video_list) == 0:
                continue
            captions = item["youtube_subtitle_text"]
            captions = select_subtitles_between_timestamps(
                subtitle_dict=load_json(
                    captions.replace(
                        "/data/",
                        tali_dataset_dir,

                ending_timestamp=100000000,
            )

            for video_path in video_list:
                temp_path = video_path.replace("/data/", tali_dataset_dir)
                video_path_actual: pathlib.Path = pathlib.Path(temp_path)

                if video_path_actual.exists():

                    item["youtube_subtitle_text"] = captions
                    yield item

    train_generator = lambda: data_generator("train", percentage=0.1)

            "test": test_data,
        }
    )
    succesful_competion = False

Hi @AntreasAntoniou , sorry to know you are facing this issue. To help debugging it, could you tell me:
- What is the total dataset size?
- Is it always failing on the same shard or is the hanging problem happening randomly?
- Were you able to save the dataset as parquet locally? This would help us determine if the problem comes from the upload or the file generation.

I'm cc-ing @lhoestq who might have some insights from a `datasets` perspective. One trick that can also help is to check the traceback when you kill your python process: it will show where in the code it was hanging Right. So I did the trick @lhoestq suggested. Here is where things seem to hang

>What is the total dataset size?

There are three variants, and the random hanging happens on all three. The sizes are 2TB, 1TB, and 200GB. 

>Is it always failing on the same shard or is the hanging problem happening randomly?

It seems to be very much random, as restarting can help move past the previous hang, only to find a new one, or not. 

>Were you able to save the dataset as parquet locally? This would help us determine if the problem comes from the upload or the file generation.

Yes. The dataset seems to be locally stored as parquet.  Hmm it looks like an issue with TQDM lock. Maybe you can try updating TQDM ? I am using the latest version of tqdm

```
⬢ [Docker] ❯ pip install tqdm --upgrade

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

``` I'm on my phone so can't help that much. What I'd advice to do is to [save_to_disk](https://huggingface.co/docs/datasets/package_reference/main_classes#save_to_disk) if it's not already done and then upload the files/folder to the Hub separately. You can find what you need in the [upload guide](https://huggingface.co/docs/huggingface_hub/guides/upload). It might not help finding the exact issue for now but at least it can unblock you.  In your last stacktrace it interrupted while embedding external content - in case your dataset in made of images or audio files that live on your disk. Is it the case ? Yeah, the dataset has images, audio, video and text.  It's maybe related to https://github.com/apache/arrow/issues/34455: are you using ArrayND features ?

Also what's your `pyarrow` version ? Could you try updating to >= 12.0.1 ? I was using pyarrow == 12.0.0

I am not explicitly using ArrayND features, unless the hub API automatically converts my files to such.  I have now updated to pyarrow == 12.0.1 and retrying You can also try to reduce the `max_shard_size` - Sometimes parquet has a hard time working with data bigger than 2GB So, updating the pyarrow seems to help. It can still throw errors here and there but I can retry when that happens. It's better than hanging. 

However, I am a bit confused about something. I have uploaded my datasets, but while earlier I could see all three sets, now I can only see 1. What's going on? 
https://huggingface.co/datasets/Antreas/TALI-base

I have seen this happen before as well, so I deleted and reuploaded, but this dataset is way too large for me to do this.  It's a bug on our side, I'll update the dataset viewer ;)

Thanks for reporting ! Apparently this happened because of bad modifications in the README.md split metadata.

I fixed them in this PR: https://huggingface.co/datasets/Antreas/TALI-base/discussions/1 @lhoestq It's a bit odd that when uploading a dataset, one set at a time "train", "val", "test", the push_to_hub function overwrites the readme and removes differently named sets from previous commits. i.e., you push "val", all is well. Then you push "test", and the "val" entry disappears from the readme, while the data remain intact.  Also, just found another related issue. One of the many that make things hang or fail when pushing to hub. 

In the following code:

```python
train_generator = lambda: data_generator("train", percentage=1.0)
    val_generator = lambda: data_generator("val")
    test_generator = lambda: data_generator("test")

    train_data = datasets.Dataset.from_generator(
        train_generator,
        num_proc=mp.cpu_count(),
        writer_batch_size=5000,
        cache_dir=tali_dataset_dir,
    )

    val_data = datasets.Dataset.from_generator(
        val_generator,
        writer_batch_size=5000,
        num_proc=mp.cpu_count(),
        cache_dir=tali_dataset_dir,
    )

    test_data = datasets.Dataset.from_generator(
        test_generator,
        writer_batch_size=5000,
        num_proc=mp.cpu_count(),
        cache_dir=tali_dataset_dir,
    )

    print(f"Pushing TALI-large to hub")

    dataset = datasets.DatasetDict(
        {"train": train_data, "val": val_data, "test": test_data}
    )
    succesful_competion = False

    while not succesful_competion:
        try:
            dataset.push_to_hub(repo_id="Antreas/TALI-large", max_shard_size="2GB")
            succesful_competion = True
        except Exception as e:
            print(e)
  ```
  
  
  Things keep failing in the push_to_repo step, at random places, with the following error:

I have a while loop that forces retries, but it seems that the progress itself is randomly getting lost as well. Any ideas on how to improve this? It has been blocking me for way too long. 

Should I build the parquet manually and then push manually as well? If I do things manually, how can I ensure my dataset works properly with "stream=True"? 

Thank you for your help and time.  > @lhoestq It's a bit odd that when uploading a dataset, one set at a time "train", "val", "test", the push_to_hub function overwrites the readme and removes differently named sets from previous commits. i.e., you push "val", all is well. Then you push "test", and the "val" entry disappears from the readme, while the data remain intact.

Hmm this shouldn't happen. What code did you run exactly ? Using which version of `datasets` ? > I have a while loop that forces retries, but it seems that the progress itself is randomly getting lost as well. Any ideas on how to improve this? It has been blocking me for way too long.

Could you also print the cause of the error (`e.__cause__`) ? Or show the full stack trace when the error happens ?
This would give more details about why it failed and would help investigate. > Should I build the parquet manually and then push manually as well? If I do things manually, how can I ensure my dataset works properly with "stream=True"?

Parquet is supported out of the box ^^

If you want to make sure it works as expected you can try locally first:
```python
ds = load_dataset("path/to/local", streaming=True)
``` @lhoestq @AntreasAntoniou I transferred this issue to the `datasets` repository as the questions and answers are more related to this repo. Hope it can help other users find the bug and fixes more easily (like updating [tqdm](https://github.com/huggingface/datasets/issues/5990#issuecomment-1607120204) and [pyarrow](https://github.com/huggingface/datasets/issues/5990#issuecomment-1607120278) or [setting a lower `max_shard_size`](https://github.com/huggingface/datasets/issues/5990#issuecomment-1607120328)).

~For the initial "pushing large dataset consistently hangs"-issue, I still think it's best to try to `save_to_disk` first and then upload it manually/with a script (see [upload_folder](https://huggingface.co/docs/huggingface_hub/guides/upload#upload-a-folder)). It's not the most satisfying solution but at least it would confirm from where the problem comes from.~

**EDIT:** removed suggestion about saving to disk first (see https://github.com/huggingface/datasets/issues/5990#issuecomment-1607186914). > @lhoestq @AntreasAntoniou I transferred this issue to the datasets repository as the questions and answers are more related to this repo.

As I've already said in other discussions, I would not recommend pushing files saved with `save_to_disk` to the Hub but save to parquet shards and upload them instead. The Hub does not support datasets saved with `save_to_disk`, which is meant for disk only. > As I've already said in other discussions, I would not recommend pushing files saved with save_to_disk to the Hub but save to parquet shards and upload them instead.

Well noted, thanks. That part was not clear to me :) Sorry for not replying in a few days, I was on leave. :) 

So, here are more information as to the error that causes some of the delay

One issue is that the uploading does not continue from the chunk it failed off. It often continues from a very old chunk. e.g. if it failed on chunk 192/250, it will continue from say 53/250, and this behaviour appears almost random.  Are you using a proxy of some sort ? I am using a kubernetes cluster built into a university VPN.  So, other than the random connection drops here and there, any idea why the progress does not continue where it left off?

This is actually the issue that wastes the most time for me, and I need it fixed. Please advice on how I can go about it.

Notice how the progress goes from 
| 77/381 to 30/381 If the any shard is missing on the Hub, it will re-upload it. It looks like the 30th shard was missing on the Hub in your case. 

It also means that the other files up to the 77th that were successfully uploaded won't be uploaded again.
