UpliftRandomForestClassifier Model object cannot be pickled when saving as joblib

[maheshv26]

UpliftRandomForestClassifier Model object cannot be pickled when saving as joblib. There seems to be no way to save UpliftRandomForestClassifier Model object

[jroessler]

You can use pickle:

import pickle
pickle.dump(urf_model, open("urf-model.pickle", 'wb'))

where urf_model is the fitted UpliftRandomForestClassifier

I got the same issue

PicklingError:can't pickle <cyfunction UpliftTreeClassifier.evaluate_KL at 0x7fc2a6f1fd90>：attribute lookup evaluate_KL on causalml.inference.tree.uplift failed

How can I fix it？
