I Am Trying To Do Some Hyperparameter Optimization Using A Script And Have Closely Followed The Example On Github. I Keep Getting This Warning When Using Optunaoptimizer:

Answered

I am trying to do some hyperparameter optimization using a script and have closely followed the example on Github. I keep getting this warning when using OptunaOptimizer:

`Study.stop` is supposed to be invoked inside an objective function or a callback.

which means that the optimization runs all have the status pending rather than completed . I have this at the end of my script:

  optimizer.start()
  optimizer.wait()
  top_exp = optimizer.get_top_experiments(top_k=3)
  print('Top experiments are:')
  print([t.id for t in top_exp])
  optimizer.stop()

so I'm not sure why I'm getting the warning.

I am using ClearML 1.12.0
Would anyone have suggestions on how I can solve this?

Hi @<1523701087100473344:profile|SuccessfulKoala55> I've updated to clearml==1.16.2 and I'm still getting the same warnings. I'm now getting an additional error which may be linked:

Exception in thread Thread-6 (_report_daemon):

That task ID that is referenced at the end of the trace is one of the draft tasks started by the optimizer.

Do you have any suggestions?
Thanks

Hi @<1727859568827961344:profile|IcyFlamingo4> , I would recommend to first upgrade ClearML SDK to the latest version (currently v1.16.2) and see if it helps
