I am trying to load sound files on a python script. I installed, loaded the right version of modules, imported successfully librosa and soundfile, and even ffmpeg (which I found was a solution to this same error for mp3 files)
import os
import json
from scipy import signal
import librosa
[...]
y, sr = librosa.load(directory_path + filename + '.webm', mono = True)
My code works on notebooks (Kaggle) but somehow, and I can't figure out why, it doesn't work when uploaded on a computer cluster. And I really need the cluster for its computational power/memory. :/
The error:
Traceback (most recent call last):
File "/cluster/apps/nss/gcc-6.3.0/python/3.8.5/x86_64/lib64/python3.8/site-packages/librosa/core/audio.py", line 146, in load
with sf.SoundFile(path) as sf_desc:

raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace'))
RuntimeError: Error opening 'input/00092.webm': File contains data in an unknown format.
During handling of the above exception, another exception occurred:

I perused the internet for a solution but no luck. Thank you for your help in advance.
