I tested ~/clearml.conf and CLEARML_DEFAULT_OUTPUT_URI , they are both ignored.

Maybe for more context, I'm using https://github.com/allegroai/clearml/blob/master/examples/frameworks/pytorch-lightning/pytorch_lightning_example.py to test and the only way I can have the model checkpoints uploaded to the server is if I set output_uri in the Task.init .

I base the assumption that I should not have to do that on the following comment from ~/clearml.conf .

# Default Task output_uri. if output_uri is not provided to Task.init, default_output_uri will be used instead.
