504 Gateway Timeout when uploading large dataset to Hugging Face Hub
Author: hotchpotch
State: open

### Description
I encountered consistent 504 Gateway Timeout errors while attempting to upload a large dataset (approximately 500GB) to the Hugging Face Hub. The upload fails during the process with a Gateway Timeout error.

I will continue trying to upload. While it might succeed in future attempts, I wanted to report this issue in the meantime.

### Reproduction
- I attempted the upload 3 times
- Each attempt resulted in the same 504 error during the upload process (not at the start, but in the middle of the upload)
- Using `dataset.push_to_hub()` method

Comments: I transferred to the `datasets` repository. Is there any retry mechanism in `datasets` @lhoestq ?

Another solution @hotchpotch if you want to get your dataset pushed to the Hub in a robust way is to save it to a local folder first and then use `huggingface-cli upload-large-folder` (see https://huggingface.co/docs/huggingface_hub/guides/upload#upload-a-large-folder). It has better retry mechanism in case of failure.

There is no retry mechanism for `api.preupload_lfs_files` in `push_to_hub()` but we can definitely add one here

https://github.com/huggingface/datasets/blob/de062f0552a810c52077543c1169c38c1f0c53fc/src/datasets/arrow_dataset.py#L5372

@Wauplin 

Thank you! I believe that to use load_dataset() to read data from Hugging Face, we need to first save the markdown metadata and parquet files in our local filesystem, then upload them using upload-large-folder. If you know how to do this, could you please let me know?



@lhoestq 

I see, so adding a retry mechanism there would solve it. If I continue to have issues, I'll consider implementing that kind of solution.
