title: scikit-learn 0.15.2 Python 3.4 Windows cannot import cluster
body: <p>I have installed scikit-learn 0.15.2 for Python 3.4 in Windows (8.1) using the MS windows installer:</p>
  
  <pre><code>https://pypi.python.org/packages/3.4/s/scikit-learn/scikit-learn-0.15.2.win-amd64-py3.4.exe
  </code></pre>
  
  <p>The installation seems to work correctly. I am able to import sklearn and some packages without any problems. However, I cannot execute:</p>
  
  <pre><code>from sklearn.cluster import KMeans
  </code></pre>
  
  <p>The import fails with the following error: </p>
  
  <blockquote>
    <p>ImportError: cannot import name 'choice'</p>
  </blockquote>
  
  <p>I have unistalled scikit-learn (using Windows uninstall) and installed the pckage again with the same problem. Any suggestions about how to fix it?</p>
