Py2Exe - Addressing NumPy and SciPy dependencies

Question

Objective (End-Goal): I want to create a stand-alone executable Python script (only one file) that includes NumPy and SciPy dependencies for my application.

Background: From my understanding, to create an executable script in Python - there are three options that are available:

1. PyInstaller
2. Py2exe
3. CxFreeze

I went ahead and tried Py2exe for my development. It appears that CxFreeze does not support the single-file option (from the documentation here). I also considered the option of using PyInstaller, but ran into issues regarding missing DLLs (similar to what is found here). The issue continued to persist even after installing the Microsoft Visual C++ 2010 Redistributable Package in my laptop.

I followed the tutorial to use Py2exe here and was able to get a dummy script executable (Hello World!) working. However, I tried to re-modify the setup.py script specific to my application to include numpy and scipy dependencies (see below):

from distutils.core import setup
import py2exe,sys,numpy,scipy

sys.argv.append('py2exe')

setup(
console=['Application.py'],
options={
  'py2exe': {
     'includes':['numpy','scipy','scipy.integrate','scipy.special.*','scipy.linalg.*'],
     'bundle_files':1,
     'compressed':True
  }
},
zipfile=None)

This is the resulting error I received when I tried running the script:

Traceback (most recent call last):
File "C:\Program Files\JetBrains\PyCharm 2018.1.4\helpers\pydev\pydev_run_in_console.py", line 52, in run_file

File "C:\Users\prest\PycharmProjects\Application\venv\lib\site-packages\py2exe\mf3.py", line 337, in _find_and_load
raise ImportError(name)
ImportError: scipy.linalg.*

These are the versions that I am using relevant for my application:

1. Python 3.4
2. NumPy 1.14.5
3. SciPy 1.1.0

Question: Can anyone provide any insight as to why I am receiving this error and any next steps to address this? I appreciate any input!

Thanks,

Preston

Answer 1

Closing - went ahead and use PyInstaller for the single-file executable. I re-modified my script to address specific dependencies (only used NumPy).
