Thank you very much. I tested it on a different machine now and it works like intended. So there must be something misconfigured with this one machine.

Yes it fully supported, and should work.
Could you share the full execution log ?

Is this working in the latest version? clearml-agent falls back to /usr/bin/python3.8 no matter how I configure clearml.conf Just want to make sure, so I can investigate what's wrong with my machine if it is working for you.

instead of the one that I want or the one of the env which it is started from.

The default is the python that is used to run the agent.
agent.ignore_requested_python_version = true agent.python_binary = /my/selected/python3.8
