ModuleNotFoundError: No module named 'sklearn.decomposition'
If the module installed, uninstall and install Sklearn again.
python -m pip install -U sklearn.
i want to import PCA from sklearn.decomposition, but following error occurs: 
"ModuleNotFoundError: No module named 'sklearn.decomposition'". (just import sklearn works)
Does someone know how i can solve this problem?
I have installed the packages in Anaconda (conda version : 4.8.3)
