Creating cx_Freeze exe with Numpy for Python

TMan picture TMan · Apr 4, 2012 · Viewed 10.7k times · Source

Im trying to create a basic exe using cx_Freeze. It works for .py programs that don't have numpy but I can't get one made correctly with numpy.

*Any ideas on how to fix this? is there something i need to include in my setup.py?

When I go to run the exe it says:

           c:\Python32\Scripts\dist>Assignment4_5.exe
           Traceback (most recent call last):
     File "C:\Python32\lib\site-packages\cx_Freeze\initscripts\Console3.py", line 2
     7, in <module>
     exec(code, m.__dict__)
     File "c:\Python32\Assignment4_5.py", line 6, in <module>
     import numpy as np
     File "C:\Python32\lib\site-packages\numpy\__init__.py", line 137, in <module>
     from . import add_newdocs
     File "C:\Python32\lib\site-packages\numpy\add_newdocs.py", line 9, in <module>

     from numpy.lib import add_newdoc
     File "C:\Python32\lib\site-packages\numpy\lib\__init__.py", line 17, in <modul
     e>
    from .npyio import *
    File "C:\Python32\lib\site-packages\numpy\lib\npyio.py", line 6, in <module>
    from . import format
    ImportError: cannot import name format

   c:\Python32\Scripts\dist>

Setup.py:

   from cx_Freeze import setup, Executable

   includeDependencies = []

   setup(
        name = "Assignment4_5PythonExe",
        version = "0.1",
        description = "Sort Methods",
        executables = [Executable("Assignment4_5.py")]
        )

This is a bug in cx_Freeze - it doesn't automatically detect that it should copy the module numpy.lib.format. It's already fixed in the development version, so if you're in a position to try that, it should work.

Otherwise, you'll need to specify that numpy.lib.format needs to be included in your setup.py. The line will look something like this:

options = {"build_exe": {"packages": ["numpy.lib.format"]}},

See also the documentation.
