title: No module named 'sklearn'
body: <p>my problem seems to be easy but i have no idea how to resolve it.
  So i got an error</p>
  
  <blockquote>
    <p>ModuleNotFoundError: No module named 'sklearn'</p>
  </blockquote>
  
  <p>when i try to import datasets and svc, but in my opinion i had installed all required packages already</p>
  
  <pre><code>C:\Python34\Scripts&gt;pip install -U scikit-learn
  Requirement already up-to-date: scikit-learn in c:\python34\lib\site-packages
  </code></pre>
  
  <p>using python 3.4</p>
  
  <pre><code>C:\Python34\Scripts&gt;pip -V
  pip 9.0.1 from c:\python34\lib\site-packages (python 3.4)
  </code></pre>
  
  <p>also using Eclipse IDE with PyDev, working on Windows</p>
  
  <p>Someone know what is going on?</p>
