M: "So I think what you need is to map your external code into the docker, is that correct?"
K: No. The code, that must be in PYTHONPATH is part of the repo being cloned by agent, but must be referenced in PYTHONPATH, because of multiple modules being referenced from that path.
M: "You can achieve both by configuring the trains.conf"
K: For variability reason, I hope that it would be possible, to configure this for each agent separately in initial command (which is obviously impossible by now). Yep, I can change this in config, but that was not the way I initially want.
Thanks for response anyway, I will try to dig into the code a bit more and in case I will be able to fix it, I will let you know via some merge/pull request.
