okay, so here’s what i found out—
calling the training entry point directly (eg /path/to/train.py ), and not instantiating the clearml Task in train.py (eg calling a method in a different module where the task is instantiated) does work calling the entrypoint with python -m , but instantiating the clearml Task within train.py also works
so the only thing that doesn’t work is calling the entrypoint with python -m and calling a method from a different module that instantiates the task.

not sure if this is considered a bug or not! but I’d happily make an issue on github if needed.

thanks again for all your help.
