Does the clearml module parse the python packages?

Yes it analyzes the installed packages based on the actual mports you have in the code.

If I'm using a private pypi artifact server, would I set the PIP_INDEX_URL on the workers so they could retrieve those packages when that experiment is cloned and re-ran?

Correct 🙂 the agent basically calls pip install on those packages, so if you configure it, with PIP_INDEX_URL it should just work like any other pip install
