减少py2exe分布大小，同时包括一些numpy函数

Question

I have a program which is currently dependent on numpy which I have been working on converting with py2exe . My issue is that even with a script such as

from numpy import array
print array(1)

that only uses the function numpy.array , I can't find any way to exclude seemingly unnecessary parts of the numpy package such as numpy.linalg in the distribution that is created by py2exe . This results in the distribution being over 80MB in size, (30MB after being zipped). There is a file in the folder called numpy.linalg._umath_linalg.pyd which is 34MB and another called numpy.linalg.lapack_lite.pyd which is 18MB - do these really need to be there?! The .exe does not run if they are simply deleted.

My question is, how can I reduce the resulting distribution size? I am aware there are alternatives to py2exe and that if I could remove dependency on numpy I wouldn't have this problem, but I would like to stick with both of these.

The following setup script is what I am using, resulting in an 87MB distribution.

from distutils.core import setup
import py2exe, sys
import shutil

sys.argv.append('py2exe') # No need to type in command line.

py2exe_options = {
        # 'excludes': ['numpy.linalg'], # Stopped the resulting exe from running
        'compressed': True, # Saves 5MB, is this at the cost of some speed?
        'optimize': 1 # I don't really understand what this does.
        }

setup(
    windows=[{'script': 'main.pyw'}],
    options={'py2exe': py2exe_options},
    )

shutil.rmtree('build', ignore_errors=True) # Remove the build folder

If anyone has any further suggestions I'd like to here them! But here is what I've done so far.

I have managed to reduce the size of the distribution from 87MB to 34MB by reinstalling numpy using an 'unoptimized' binary downloaded from here . I believe this is likely to run much slower when doing linear algebra operations, however it works fine for me working with arrays.

UPDATE
I have now got my distribution down to 28MB by altering the py2exe options in my setup.py script.

import distutils.core import setup

py2exe_options = {
        'compressed': True,
        'optimize': 1, # 2 does not work.
        'excludes': ['pydoc', 'doctest', 'pdb', 'inspect', 'pyreadline',
            'locale', 'optparse', 'pickle', 'calendar']
        }

setup(windows=['main.py'], options={'py2exe':py2exe_options})
