title: OpenCV and numpy version mismatch
body: <p>How to check what version of openCV is compatible with a particular version of numpy?</p>
  
  <p>I am using python 2.7.5 and installed numpy 1.7.1 on windows 7.
  As i am working under firewall and I don't have any access to any proxy, hence I cant use pip or any windows provided packages like anaconda or cobra etc.</p>
  
  <p>How can i create the environment with python2, openCV and numpy manually?</p>
