I’m not sure if this was solved, but I am encountering a similar issue.

Yep, it was solved (I think v1.7+)

With

spawn

and

forkserver

(which is used in the script above) ClearML is not able to automatically capture PyTorch scalars and artifacts.

The "trick" is to have Task.init before you spawn your code, then (since your code will not start from the same state), you should call Task.current_task(), which would basically make sure everything is monitored.
(unfortunately patching spawn is trickier than fork so currently it need to be done manually)
