title: error importing numpy in python 3.5
body: <p>I tried installing numpy with homebrew, but instead it installed in the Python 2.7 version. I found this out by following the answer on this post: <a href="https://stackoverflow.com/questions/22543745/cant-import-numpy">Can&#39;t import numpy</a></p>
  
  <p>Which is very strange especially since I specifically asked for python3: </p>
  
  <pre><code>M$ brew install numpy --with-python3
  Warning: homebrew/python/numpy-1.11.1 already installed
  </code></pre>
  
  <p>However, when I try importing it in Python 3.5 I always get the same error:</p>
  
  <pre><code>  File "Dataframe.py", line 1, in &lt;module&gt;
      import numpy as np
  ImportError: No module named 'numpy'
  </code></pre>
  
  <p>How can I get it to work as intended? I am on mac os 10.11.3</p>
