🐛 Bug Report

it seemed we cannot import demucs in our own python code?

To Reproduce

(Write your steps here:)

1. init a new conda env with

   conda create --name mydemucs python=3.9 -y

   2, activate conda env

   conda activate mydemucs

3, install the edge version with

python3 -m pip install -U git+https://github.com/facebookresearch/demucs#egg=demucs

4, using the following code

import demucs.api

if __name__ == '__main__':
     separator = demucs.api.Separator()

it shows

ModuleNotFoundError: No module named 'demucs.api'; 'demucs' is not a package

Expected behavior

we could import and use demucs api correctly ...

That's so interesting... I can't reproduce. Maybe can you run ls /home/xxx/miniconda3/envs/mydemucs/lib/python3.9/site-packages/demucs?

[gillbates]

ls /home/xxx/miniconda3/envs/mydemucs/lib/python3.9/site-packages/demucs

api.py    audio.py    demucs.py   ema.py       hdemucs.py   __init__.py  pretrained.py  py.typed  repitch.py  separate.py  spec.py    svd.py    transformer.py  wav.py

it seemed everything is included already.

Are you sure you've activated the environment before running your script?

Are you sure you've activated the environment before running your script?

yes .... already several times ... it could be found even in site-packages in pycharm ...

[CarlGao4]

Can you run this:

import sys
print("\n".join(sys.path))

Maybe... You can try importing it like this:

import demucs
import demucs.api
if __name__ == "__main__":
   ...

@CarlGao4 I fixed this by re-install conda instead of miniconda ... thx !!!
