Build from source python 3.12 fails #988

EnricoBeltramo · 2024-05-28T22:20:40Z

Expected behaviour

I tried to build the tag 80 in python 3.12, but build fails

Write here how did you expect the library to function.
correct build from source

Actual behaviour

Write here what went wrong.
install of some dependencies (i.e. numpy) fail with this error:
AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?
the dependencies versions of numpy and setuptools are outdated and broken in python 3.12. Is it possible to use latest versions of those packages?

Steps to reproduce

example code: build from source as tutorial in main page
operating system: Ubuntu 22.04
architecture (e.g. x86): x86
opencv-python version: 80

Issue submission checklist

This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
I'm using the latest version of opencv-python

I already tried that and it didn't work.

I'm also getting the same error with the latest merged updates:

I encountered the same problem while running pip wheel . --verbose |& tee install_opencv.log. It worked after removing the ==59.2.0" from the "setuptools==59.2.0" https://github.com/opencv/opencv-python/blob/4.x/pyproject.toml#L16.

sibocw · 2024-06-19T10:12:31Z

Thank you @zhanwenchen, I also encountered the same issue (even after following the StackOverflow answer above), and solved it the same way. I think the ==59.2.0 prevents pip from using the most up-to-date setuptools that has this API change addressed.

Is there a particular reason why there's such a strict requirement for setuptools? Can I make a PR to remove it (or change it to >=59.2.0)?

Currently, opencv-python fails to build under python 3.12. This patch fixes that problem by permitting the use of any setuptools>=59.2.0, rather than mandating that specific version. This patch fixes opencv#988. See discussion there for details. I have tested by successfully installing opencv-python.
