The main issue is the model itself is stored on your files server that is/was configured to " None " this means that you cannot access it from anywhere other than tha actual machine (i.e. inside a container this is not accessible).
Change your configuration (i.e. clearml.conf) files_server: http://<Local_IP>:8081
Then rerun the example (importantly, re run the training so a new model will be generated and registered under the new address, with the IP). should work after that
