RandomForest classifier from sklearn==0.22.1 gives AttributeError

[priesgo]

The error message was AttributeError: 'RandomForestClassifier' object has no attribute 'n_features_in_'

Is there any range of sklearn versions which are explicitly supported?

The statement in setup.py install_requires=["scikit-learn >= 0.22"],, implies than an "explicitly supported version (i.e. last for which everything was known to be working) was 0.22.
