ImportError: numpy.core.multiarray --- Numpy 2.0.0

[JuliusBairaktaris]

Expected behaviour

I am currently using NumPy 2.0.0rc2 in conjunction with the recently released OpenCV 4.10.0.82 and have encountered the following error:

Actual behaviour

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0rc2 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

ImportError: numpy.core.multiarray failed to import

Steps to reproduce

• Windows 11
• Python 3.12.3
• opencv-python==4.10.0.82
• numpy==2.0.0rc2

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

Kind regards,

There is already issue about numpy2 support: #943
