Linux support for Demucs

If your distribution has at least Python 3.8, and you just wish to separate tracks with Demucs, not train it, you can just run

pip3 install --user -U demucs
# Then anytime you want to use demucs, just do
python3 -m demucs -d cpu PATH_TO_AUDIO_FILE_1
# If you have added the user specific pip bin/ folder to your path, you can also do
demucs -d cpu PATH_TO_AUDIO_FILE_1

If Python is too old, or you want to be able to train, I recommend installing Miniconda, with Python 3.8 or more.

conda activate
pip3 install -U demucs
# Then anytime you want to use demucs, first do conda activate, then
demucs -d cpu PATH_TO_AUDIO_FILE_1

Of course, you can also use a specific env for Demucs.

Important, torchaudio 0.12 update: Torchaudio no longer supports decoding mp3s without ffmpeg installed. You must have ffmpeg installed, either through Anaconda (conda install ffmpeg -c conda-forge) or as a distribution package (e.g. sudo apt-get install ffmpeg).
