Cannot import anything from sklearn.ensemble

Question

from sklearn.ensemble._forest import VotingClassifier
from sklearn.ensemble import RandomForestRegressor

when I try to import anything from ensemble, there's always error like:

I tried

pip install -U scikit-learn
conda install -c conda-forge scikit-learn 

Answer 1

Don't mix conda with pip.

Try these steps:

1. pip uninstall sklearn and then pip install -U scikit-learn

2. Replace

   from sklearn.ensemble._forest import VotingClassifier

   with

   from sklearn.ensemble import VotingClassifier
