Setuptools warning

[Adoro]

When I start tiangolo/uwsgi-nginx-flask:python3.7 I get the following warning:

Checking for script in /app/prestart.sh
Running script /app/prestart.sh
Running inside /app/prestart.sh, you could add migrations to this file, e.g.:

#! /usr/bin/env bash

# Let the DB start
sleep 10;
# Run migrations
alembic upgrade head

I believe this has to do with supervisor but it looks like supervisord version 4.1.0 is being used which is compatible with Python 3.4 and up. Anyone familiar with this issue and knows how to solve it?

I just tried it and I don't get that error. Could it be that you are installing some Python 2 packages?

If your problem persists, please add a small, self-contained example to see the error.
