optuna notebook fails: Can't instantiate abstract class DaskStorage with abstract methods #119

Closed murphyk closed 1 year ago

murphyk commented 3 years ago

I am running https://cloud.coiled.io/examples/jobs/optuna. In the cell 'Train with Optuna' I get this error

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

TypeError: Can't instantiate abstract class DaskStorage with abstract methods get_study_directions, set_study_directions, set_trial_value

@murphyk Did you figure out what was causing this issue?

ian-r-rose commented 3 years ago

Thanks for the ping on this @deepakagrawal . The issue was a version mismatch -- it should be fixed now, are you still seeing issues?

shughes-uk commented 1 year ago

This is quite stale and we no longer maintain these specific examples. Package sync should resolve any version mismatch issues

For reference this is an updated example https://docs.coiled.io/user_guide/examples/dask-optuna-hpo.html
