Then as you suggested, I would just use sys.path it is probably the easiest and actually very safe (because the subfolders are Always next to the "main" source code)

Hi SkinnyPanda43

Let's say that I install the shared libs with pip in editable mode on my development evironment, how does the clearml-agent will handle those libraries if I submit a job

So installing packages from local folders with "-e" is in general ill-advised.
But using a full git path should work out of the box. for example if you install pip install https://github.com/user/repo/repo.git then the agent will be able to install it on the remote machine. The main challenge in your setup is that the agent is installing the requirements will have a full path to the folder and not a relative one...
I would try the following and play around with the path (I think the root is the main repo path)
Task.add_requirements("my_nested_package", "-e ./relative/path/to/package") Task.init(...)wdyt?

They are on the same repo on git, something like:
my-repo train project1 project2 libs lib1 ...

Thank you, sorry for the daly, I have been playing around with this setup, right now I am generating a requirements.txt with git links to the sibling packages, I had to set on the agent to force the use of the reuqirements.txt. But I am starting to wonder whether It would be easier just changing sys,path on the scripts that use the sibling libs.

that depends, how would the sibling packages get to a remote machine ?
