[mxzhao]

I tried a mp3, but it failed:
Using cuda for separating ..
/home/zeppsh/anaconda3/envs/music/lib/python3.7/site-packages/librosa/core/audio.py:165: UserWarning: PySoundFile failed. Trying audioread instead.
warnings.warn("PySoundFile failed. Trying audioread instead.")
Traceback (most recent call last):

raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace'))
RuntimeError: Error opening '2.mp3': File contains data in an unknown format.

Is there any limitation about the mp3 format?
would you please share your test mp3: ./resources/vocals_accompaniment_10s.mp3

Mp3 is OK. The mp3 file is uploaded. The installation is simplified. Try pip install bytesep and follow the updated README?
