pip wheel . --verbose didn't build a wheel for opencv, just opencv_contrib and numpy

[johncblacker]

Expected behaviour

Build a .whl file for opencv as well as one for opencv_contrib

Actual behaviour

.whl for opencv_contrib was built but .whl file for opencv was not built

Steps to reproduce

export ENABLE_CONTRIB=1

ubuntu 22.04 on WSL2

x86-64

• opencv-python version did git checkout tag/4.5.5 in the opencv_contrib subdirectory did git checkout tag/4.5.5 in the opencv subdirectory

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'm really confused now. I did the git checkout tags/4.5.5 in the opencv subdir and the opencv_contrib subdir; however, when the build was complete I got a opencv_contrib_python-4.8 wheel file! After I did the checkouts I did a git status and each of them were pointing to the 4.5.5 version yet the build ended up for 4.8; also after the build was complete I went into each of the subdir's and they were back to "origin/4.x" so I'm not understanding how/why that happened. I'm trying to build version 4.5.5 but am unable to do so...perhaps I'm doing something wrong? Need some help please.

setup.py updates submodules to be sure that opencv-python and submodules are consistent in https://github.com/opencv/opencv-python/blob/43cd7169cb92d96898d59753796678495b95c833/setup.py#L51. It's debatable solution and may lead to confusion. Will check if it could be dropped.

I believe that to be accurate it must be 64-bit OS (bullseye) on RPi4; I tried installing mediapipe==0.10.3 and it will not install

On 32-bit RPi4 bullseye…

If you are saying that it should install on 32-bit bullseye, RPi4, then there is a problem.

Thanks for the reply.
