Wine + Python 3.5 or 3.6 + Numpy

Versions

• Pyinstaller 3.2.1 or master
• Python 3.5.x and above
• Wine: wine-devel

Recrate

• Any linux, docker, VM, etc.
• Install wine-devel
• Install pyinstaller
• pip install numpy

Example python:

import numpy as np
a = np.array([1, 2, 3])
print(a)

Result

It builds fine. But doesn't work when you execute it.

Executable output after building with pyinstaller --debug test.py:

Workaround

The only way I've been able to fix this is by downgrading python to 3.4.x, then everything works fine.

What I've tried

Different versions of 3.5.x. Downloading the mkl versions of the windows binaries. Including lots of other libraries that didn't seem to make a difference. Different wine distributions. Different OS's. Different versions of pyinstaller.

Start by reproducing the reported Python 3.5 or 3.6 build under Wine with the provided test.py and numpy example. Trace the failure from pyi_rth_win32comgenpy.py through pyimod03_importers.py, then verify that the generated executable runs successfully without downgrading Python to 3.4.
