uWSGI and joblib Semaphore: Joblib will operate in serial mode

Question

I\'m running joblib in a Flask application living inside a Docker container together with uWSGI (started with threads enabled) which is started by supervisord.

The start

Answer 1

Well, I did find an answer to my problem. It solves the issue in terms of being able to run a joblib dependent library with supervisor and nginx in docker. However, it is not very satisfying. Thus, I won't accept my own answer, but I am posting it here in case other people have the same problem and need to find an okayish fix.

The solution is replacing uWSGI by gunicorn. Well, at least I know now whose fault it is. I would still appreciate an answer that solves the issue using uWSGI instaed of gunicorn.
