title: ImportError: No module named PyQt4.QTGUI
body: <p>I have installed the PyQt4 library and have the following at the start of the code</p>
  
  <pre><code>from PyQt4.QtGui import *
  ......
  </code></pre>
  
  <p>This runs perfectly well when I run the code from the windows Python Gui (IDLE).
  However, when I tried to run the code from Cygwin, I get the below error:</p>
  
  <pre><code>ImportError: No module named PyQt4.QTGUI
  </code></pre>
  
  <p>Can I know what is wrong here?
  Thanks.</p>
