No output audio via docker

Hi,

I've tried on Ubuntu and Windows (Linux containers on windows) and I get feedback from the container, it downloads the stems model and is see contents in my model directory but then no files in the output directory.

The command i'm running:

docker run -v C:\t\input:/input -v C:\t\output:/output -v C:\t\model:/model -e MODEL_PATH=/model researchdeezer/spleeter separate -i /input/audio_1.mp3 -o /output

Thanks in advance,

Start by reproducing the exact `docker run` command from the issue, checking the `/input`, `/output`, and `/model` bind mounts and the container output. Done means the separation completes and files appear in the host output directory on the reported environments.
