2.0.0 sys.stderr attribute error packaged with cx_freeze #26862
Description
Describe the issue:
I have tested by only upgrading to 2.0.0 with numpy, and noticed the package build with cx freeze would be successful, until I tried to open the executable, and I would receive this window pop up.
Version 1.26.4 would package fine with cx_freeze and I've not upgrade cx_freeze.
If I have more time at the end of my day I will trek through some of the files and see if sys.stderr is modified anywhere in your code.
Sorry for the short code block below, it happens on launch.
Reproduce the code example:
import numpy as npError message:

AttributeError: 'NoneType' object has no attribute 'write'Python and NumPy Versions:
2.0.0
Runtime Environment:
Using a package build with cx freeze, on windows 10. Cx freeze is version 7.1.1
Context for the issue:
I can use 1.26.4, I just noticed this bug during a package build using 2.0.0. I realise 2.0.0 is a major release, and if stderr is potentially a None on import, then it might be worth looking at.

I really don't see anything here related to NumPy (numpy isn't in the stacktrace, numpy has nothing to do with
sys.stderr, ...). If it really has to do with the NumPy version as you say, I half expect that installing/uninstalling it just changed other versions as well.Going to close this for now, if you can get a better idea of why NumPy is involved, please post and we can reopen.

I did have time to check the previous version, which had a utils.py, which reassigned sys.stderr, but in 2.0.0, that file doesn't seem to exist... I think. I will have a look further when I get time, thanks for getting back.

Hi folks,
I'm seeing the same problem, here is the traceback I'm getting:
Here is the line that crashes:
numpy/numpy/f2py/cfuncs.py
Line 19 in b3feb3c
When frozen without a console (common in GUI applications),
