title: Numpy- How to fix autocompletion in PyCharm 3.1.3
body: <p>I was working on my project in PyCharm 3 that suddenly the power went off. After that when I tried to start PyCharm I encountered with a huge number of warnings about the last configuration! So I accept to reset all configuration. </p>
  
  <p>Now when I import <code>numpy</code> and try to use autocompletion it doesn't show anything! It works but there is no autocompletion popup. I have no problem with <code>OpenCV</code> import which its autocompletion works fine(as before). </p>
  
  <p>I read <a href="https://stackoverflow.com/questions/12517535/pycharm-autocomplete">this</a> and <a href="https://stackoverflow.com/questions/14611714/python-pycharm-ctrl-space-does-not-bring-up-code-completion">this</a> and tried both of them but that doesn't work. I uninstalled <code>NumPy</code> and reinstalled it again but the problem didn't solved!</p>
  
  <p>I'm using windows 7</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I also update my <code>PyCharm</code> to 3.1.x(I removed the previouse version with its settings). The problem exists yet. </p>
