Awesome! Yeah I can also do that but at the time being I simply amended the colab including the zip save option and it works, now submitting is no longer an issue, however I am encountering a new issue when generating predictions and by having a look at the traceback seems now that h2o is rising some errors. It seems that once loading the models, there is no initialisation of the h2o clusters which might be caused by Java:
h2o.exceptions.H2OConnectionError: Could not establish link to the H2O cloud http://localhost:54321 after 5 retries
h2o.exceptions.H2OStartupError: Cannot find Java. Please install the latest JRE from

@alfarzan Did you hear if anyone else was facing the same issue?
