Multiprocessing windows error
Hi ! Thanks for reporting.
This looks like a bug, could you try to provide a minimal code example that reproduces the issue ? This would be very helpful !

Otherwise I can try to run the wav2vec2 code above on my side but probably not this week..
As described here https://huggingface.co/blog/fine-tune-xlsr-wav2vec2

When using the num_proc argument on windows the whole Python environment crashes and hanging in loop.
For example at the map_to_array part.
An error occures because the cache file already exists and windows throws and error. After this the log crashes into an loop
