title: Cannot import QtCore or QtGui from PyQt4
body: <p>I have found plenty of posts regarding this issue, but no answers that work for me.</p>
  
  <p><strong>PROBLEM:</strong><br>
  I am trying to run this code:<br>
      <code>from PyQt4 import QtCore, QtGui</code><br>
  I get this error in return:<br>
      <code>ImportError: cannot import name QtCore</code><br>
  I append the path to PyQt4 to sys.path (C:\Python27\Lib\site-packages\PyQt4) and importing just PyQt4 throws no errors. I can see that QtCore.pyd and QtGui.pyd are in that directory and the directory has its <code>__init__.py</code> file.</p>
  
  <p><strong>Specs:</strong><br>
  Windows 7 x64<br>
  python v2.6.8<br>
  PyQt v4.10.4</p>
