Python Question

No module named builtins

I'm trying to convert my .py script into an executable using py2exe. I've had a number of issues so far that have been largely addressed by the "options" in the setup file below. But now I have a problem that I have not been able to find a solution for, and wondering if others have had this same issue and fixed it.

When I execute the setup file below using "python setup.py py2exe" it gives me an executable but when I run it, it complains "No module named builtins".

The only other post I could find on this subject indicated that builtins is a python3 thing, but I'm running 2.7.

Appreciate any advice or tips on this.

from distutils.core import setup
import py2exe

from distutils.filelist import findall
import os
import matplotlib
matplotlibdatadir = matplotlib.get_data_path()
matplotlibdata = findall(matplotlibdatadir)



setup(
console=['DET14.py'],
options={
'py2exe': {
'packages' : ['matplotlib', 'pytz'],
'dll_excludes':['MSVCP90.DLL',
'libgdk-win32-2.0-0.dll',
'libgobject-2.0-0.dll',
'libgdk_pixbuf-2.0-0.dll'],
'includes':['scipy.sparse.csgraph._validation',
'scipy.special._ufuncs_cxx']
}
},
# data_files=matplotlibdata_files
data_files=matplotlib.get_py2exe_datafiles()
)


Here is the full listing of what the error message looks like:

Answer

I finally got this working. It turned out that I had some errors in the original setup file, some of which were outright dumb, and some simply relfected my lack of understanding of how the parameters of the setup command works. I will add that this latter class of errors was only resolved with some Shelock Holmes-style sleuthing and plain old trial and error. By that I mean that I have still not found any documentation that calls out the meaning and usage of the parameters of the setup command. If anyone has that info and could pass it along that woudl be much appreciated.

With that as background, here is the answer:

There were 2 basic problems:

  1. The list of packages in the aboe setup file was woefully incomplete. I am still not certain that the rule is that you have to list every single package that your program relies upon, and some which it may rely upon that you didn't know about (i.e., pytz, for example...). But when I did that, I had something at that point that I could eventually get to work.

  2. The error message in the above original question sort of looks like my program had a dependence on a thing called "patsy", andthis confused me because I had no idea what that is, but it turns out that statsmodels (whihc is core to my project) has a dependency on patsy, so it needed to be included in the "packages" list.

Below is the setup file that ended up working. I hope this description of the logic behind the fix turns out to be helpful to others facing the same kind of problem.

from distutils.core import setup
import py2exe

from distutils.filelist import findall
import os
import matplotlib
matplotlibdatadir = matplotlib.get_data_path()
matplotlibdata = findall(matplotlibdatadir)



setup(
    console=['DET14.py'],
    options={
             'py2exe': {
                    'packages' : ['matplotlib', 'pytz','easygui',\
                                  'statsmodels','pandas','patsy'],
                    'dll_excludes':['MSVCP90.DLL',
                                    'libgdk-win32-2.0-0.dll',
                                    'libgobject-2.0-0.dll',
                                    'libgdk_pixbuf-2.0-0.dll'],
                    'includes':['scipy.sparse.csgraph._validation',
                        'scipy.special._ufuncs_cxx']
                   }
        },
    data_files=matplotlib.get_py2exe_datafiles()
)
