title: Why can i not import sklearn
body: <p>Why am I not able to import sklearn?
  I downloaded Anaconda Navigator and it has scikit-learn in it. I even pip installed sklearn , numpy and scipy in Command Prompt and it shows that it has already been installed, but still when I import sklearn in Python (I use PyCharm for coding) it doesn't work. It says 'No module named sklearn'.  </p>
