Packaging with pyinstaller: PyQt4 module not found

Hi everyone and thanks for reading. I'm packaging my python code in a single file using pyinstaller, but when I run my packaged file I get the following error:

Traceback (most recent call last):
File "<string>", line 21, in <module>
File "C:\Users\****\Desktop\pyinstaller-2.0\pyinstaller-2.0\PyInstaller\loader\iu.py", line 409, in importHook
ImportError: No module named PyQt4.QtCore

I don't know what this error is telling me, especially since there is no dir name pyinstaller-2.0 on my desktop and I did not use PyQt4 at all.

Imported modules: Tkinter, tkFileDialog, tkMessageBox, multiprocessing, os, sys, time, numpy, scipy.weave, pywt, matplotlib.pyplot

I think the problem is related to multiprocessing, since I did not experience this error before. I used this recipe to implement the multiprocessing module correctly.

If you were using PyQt then the only way to import the modules with PyInstaller is to use

 from PyQt4 import QtCore, QtGui

rather than 

 import PyQt4.QtCore, PyQt4.QtGui

which your error implies. However, you say that you're not using PyQt.

PyQt is an optional dependency of matplotlib so there is a chance that PyInstaller is checking the matplotlib module and consequently including PyQt.

I would suggest excluding the PyQt module from the build; in your .spec file, search out the line for the Analysis class - something like

Analysis( ..., excludes=['PyQt4', 'PyQt4.QtCore', 'PyQt4.QtGui'])

and edit the excludes keyword arg as suggested above.
