SuccessfulKoala55 thanks for letting us know. I actually had that issue starting from this morning.
In these cases, the agent spinning the docker container for the task might fail with an import error coming from the pathlib2 code. We've just released clearml agent v1.1.2 with updated requirements that should solve the issue
SuccessfulKoala55 can you describe how the failure behaviour will look like?
Note to use either python -m pip install -U six>=1.13.0
or python3 -m pip install -U six>=1.13.0
, depending on the python version available in your docker image.
