ImportError: cannot import name 'CombinedStopper' from 'ray.tune.stopper'

I'm trying to import parts of the package in a Kaggle notebook, but I'm getting this import error. It's python 3.7.

Any suggestions? Thanks!

from tune_sklearn import TuneGridSearchCV
# import tune_sklearn as ts

hey @kylegilde what version of Ray are you on? Can you make sure to upgrade to Ray 1.2?

That did the trick. Thanks
