❓ Questions

I installed Python 3.10.0 on my laptop, installed ffmpeg, set the paths for each, and installed the latest versions of demucs and torchaudio. I tried to separate vocals from a wav file, but I keep getting the following message and it doesn't work. Despite numerous attempts to fix the errors with the help of AI like ChatGPT, I keep getting the same result dozens of times. What is the problem and how can I fix it? Please help.

File "c:\Vpan\demucs_env\lib\site-packages\torchaudio_backend\\utils.py", line 222, in dispatcher raise RuntimeError(f"Couldn't find appropriate backend to handle uri {uri} and format {format}.") RuntimeError: Couldn't find appropriate backend to handle uri separated\htdemucs_ft\song-I16\drums.wav and format None.
