SuccessfulKoala55 Thanks for getting back to me. My image contains clearml-agent==1.9.1 . There is a recent release to 1.9.2 and now on every run the agent installs this newer version thanks to the -U flag which is being passed. From the docs it looks like there may be a way to prevent this upgrade but it's not clear to me exactly how to do this. Is it possible?
