GitHub issue #5479: audiofolder works on local env, but creates empty dataset in a remote one, what dependencies could I be missing/outdated
State: closed | Created: 2023-01-27T20:01:22Z

### Describe the bug

I'm using a custom audio dataset (400+ audio files) in the correct format for audiofolder. Although loading the dataset with audiofolder works in one local setup, it doesn't in a remote one (it just creates an empty dataset). I have both ffmpeg and libndfile installed on both computers, what could be missing/need to be updated in the one that doesn't work? On the remote env, libsndfile is 1.0.28 and ffmpeg is 4.2.1.

from datasets import load_dataset
ds = load_dataset("audiofolder", data_dir="...")


Here is the output (should be generating 400+ rows):
Downloading and preparing dataset audiofolder/default to ...

        num_rows: 1
    })
})






Here is my pip environment in the one that doesn't work (uses torch 1.11.a0 from shared env):
