fixed by reinstalling sklearn

Hi, I am using sklearn through Anaconda and tried to reinstall it. It still doesn't work.

install these ==>> pip install -U scikit-learn scipy matplotlib
if still getting the same error then ,
make sure that your imoprted statment should be correct. i made the mistike while writing ensemble so ,(check spelling)
its
should be from sklearn.ensemble import RandomForestClassifier

I solved this issue by updating my sklearn.
