create executable for application using opencv?

Question

I have designed a small application in Python under Windows, that uses opencv. I amm trying to create an executable so that anyone can install and use it, without having to install python/opencv/numpy . . .

I tried to use py2exe for this. It actually creates a .exe file, even though I have a warning during the build :

*** copy dlls ***
copying C:\Windows\system32\MSVFW32.dll -> 
...
The following modules appear to be missing
['cv2.cv']

When I try to run the .exe file using the command line, I see the message :

ImportError: numpy.core.multiarray failed to import

My setup.py file is pretty simple :

# creating executable here
from distutils.core import setup
import py2exe, sys, os

sys.argv.append('py2exe')

setup(
    options = {'py2exe': {'bundle_files': 1}},
    console=['facemovie.py'],
    zipfile = None,
)

Any idea how I can solve this? This is the very first time I want to deploy, and I may be missing something.

Thanks !

Answer 1

I would also recommend using PyInstaller. I used it for a project of mine that referenced both pycrypto and twisted and it worked like a charm.

According to this post, py2exe is not detecting that this module is needed inside the ZIP archive. I don't know the right syntax so you'll have to check the docs, but you could try:

python setup.py py2exe -p cv2

Or you could try to tweak setup.py to the following:

options = {'py2exe': {'bundle_files': 1, 'packages': 'cv2' } },

And if you are willing to try something completely different, take a look at bbfreeze:
