title: OpenCV - python 3.x and windows - what version of Numpy?
body: <p>I downloaded openCV from <a href="http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv" rel="nofollow">http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv</a> and installed it. When I tried to run it:</p>
  
  <pre><code>import cv2
  </code></pre>
  
  <p>I got error message:</p>
  
  <pre><code>RuntimeError: module compiled against API version a but this version of numpy is 9
  Traceback (most recent call last):
  File "&lt;input&gt;", line 1, in &lt;module&gt;
  File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition
   5.0.3\helpers\pydev\pydev_import_hook.py", line 21, in do_import
  module = self._system_import(name, *args, **kwargs)
  ImportError: numpy.core.multiarray failed to import
  </code></pre>
  
  <p>I guess I need to set up virtual enviroment and install different version of Numpy, but what exact version of Numpy I need to install?</p>
