Exception occurs while importing wx on M1 machine

Question

I installed wxPython version 4.1.1 from pip3 and my python version is 3.8.9 on a M1 processor running MacOS Monterey.

Importing wx results in the following exception:

Traceback (most recent call last):
  File "myPythonProgram.py", line 1, in <module>
    import wx
  File "/Library/Python/3.8/site-packages/wx/__init__.py", line 17, in <module>
    from wx.core import *
  File "/Library/Python/3.8/site-packages/wx/core.py", line 12, in <module>
    from ._core import *
ImportError: dynamic module does not define module export function (PyInit__core)

I tried the following options but none of the following seemed to have worked and the result in the same exception, stated above:

• Tried wxPython(4.1.1) installation using pip - python3 -m pip install -U --user wxPython==4.1.1
• Tried wxPython(4.1.2) with pip3 install -U --user ./wxPython-4.1.2a1.dev5259+d3bdb143-cp38-cp38-macosx_11_0_universal2.whl
• Tried compilation/installation of wxPython from source code

Any hints to resolve the issue?

Answer 1

I'm able to resolve the issue using by executing the following steps:

1. Install native minforge release from here
2. Create a virtual environment and install wxpython from mini-forge

• conda create --name my_env_py38 python=3.8
• conda activate my_env_py38
• conda install -c conda-forge wxpython # installs wxPython version 4.1.1
