You can try to add the --debug flag to get more information

Are you running the agent yourself?

Yes I am running the agent by calling clearml-agent daemon --queue default in my virtual environment on my local computer.

Thank you, I did not think about that. It helped a lot! I found out that the problem causing the unicode error was, that only the 'python' command was set up on my windows machine, but not the 'python3' command. This was the exact error for documentation:

DEBUG:clearml_agent.commands.worker:Searching for python3
