ImportError: cannot import name '_ni_support' — Using cx-freeze with scipy

问题

I have used cx-freeze to make an executable file from my python 3 script. The issue is that apparently cx-freeze is having a hard time importing scipy scripts. I had to resolve other issues previously, e.g. adding the tcl library files manually. Anyway, my setup files is below:

from cx_Freeze import setup, Executable
import os 

os.environ['TCL_LIBRARY'] = "C:\\Users\\Gobryas\\AppData\\Local\\Continuum\\anaconda3\\tcl\\tcl8.6"
os.environ['TK_LIBRARY'] = "C:\\Users\\Gobryas\\AppData\\Local\\Continuum\\anaconda3\\tcl\\tk8.6"

additional_mods = ['numpy.core._methods', 'numpy.lib.format']

setup(name = "Curve Characterization" ,
  options = {'build_exe': {'includes': additional_mods}},
  version = "0.1" ,
  description = "" ,
  executables = [Executable("curvCharLite.py")])

This is the error that I get:

ImportError: cannot import name '_ni_support'

PS 1: There is a similar issue asked here, but no helpful answer really.

PS 2: I'm using scipy 1.1.0, cx-freeze 5.1.1, and python 3.6.5

回答1:

So, I think I found a solution for this problem inspired by the post by @fepzzz. Looks like there are bad conflicts between cx-freeze and scipy which can be avoided as follows. I needed to modify the include_files build option as below:

import os
import scipy

includefiles_list=[]
scipy_path = os.path.dirname(scipy.__file__)
includefiles_list.append(scipy_path)

build_options = dict(packages=['matplotlib'], #this line solves an issue w/ matplotlib
                 include_files=includefiles_list, #this line is for scipy issue
                 includes=['matplotlib.backends.backend_qt5agg']) #this line solves another issue w/ matplotlib

Hope this helps others.
