title: ERROR : No module named ""
body: <p>I got a small problem using pylint to check my python code. 
  I use the opencv library in my code, which results in </p>
  
  <pre><code>E: 85: Module 'cv' has no 'MoveWindow' member
  </code></pre>
  
  <p>errors in my code. 
  The reason for that is explained here : 
  <a href="http://www.logilab.org/blogentry/78354" rel="nofollow">http://www.logilab.org/blogentry/78354</a></p>
  
  <p>So I did just as they asked and created an astng_cv.py file in my code. 
  I updated my PYTHONPATH so that he knows where my file is. </p>
  
  <p>But when I try : </p>
  
  <pre><code>pylint --load-plugins astng_cv eagle_road.py
  </code></pre>
  
  <p>I keep having a :</p>
  
  <pre><code>ImportError: No module named astng_cv
  </code></pre>
  
  <p>error. </p>
  
  <p>This is quite annoying and I don't really know what to do to solve the issue. </p>
  
  <p>Would you have an idea? </p>
  
  <p>Thanks by advance ! </p>
