cx_freeze and scipy: "ImportError: cannot import name vode"

i am trying to create an executable from my python script. My script runs fine, but after freezing it, starting the .exe gives me the following error:

I am using Python 3.2.3, Scipy 0.12.0b1, Numpy 1.7.0 and Matplotlib 1.2.0 (all 32bit).

Any ideas/hints on how to solve this? My guess is i have to include something manually in my freezing script, but i am running out of guesses :-(

I got it finally to work, but I am very unsatisfied with my solution:

1) copy _odepack.pyd and odepack.py from the SciPy package to my program folder

2) in odepack.py change from . import _odepack to import _odepack (otherwise ValueError: Attempted relative import in non-package is raised)

3) in my main change from scipy.integrate import odeint to from odepack import odeint

Now it is working as expected and after using cx_freeze it is still working.
Still got no idea why it would not work before :-(

Thanks ThomasK for pushing me in the right direction though :-)

I finally got around this vode-problem by specifying "scipy.integrate.vode" as an include in the cx setup-file. This resulted in a file "scipy.integrate.vode.pyd" to end up in the build folder. I am using SciPy 0.11, Python 3.2.3 and the latest cx on Windows.

But adding such a "scipy.integrate.vode" file manually to the build folder would not fix the problem for me either, even though such manual-include-fixes were needed for many other .pyd files cx could not find either (and whereby the above setup.py include-solution would not work instead)...

Thanks for sharing your distress and wisdom, would not have managed to freeze my program otherwize...
