[Question] Python 3.13t (free-threaded) compatibility

[szalpal]

Hello!

Is there any plan of supporting Python3.13t (i.e. free-threaded Python)?

Not sure if this is a problem with opencv or with numpy, but I've had a great waste of time for multiple hours trying to make both of these libraries even just import on 3.13.2 thread unlocked...

So I'll just drop this here numpy/numpy#28275

What is the current status on the compatibility? I tried to install opencv using pip and python 3.13.2t resulting in a failure, I checked #1051 with a potential solution for Linux systems to build the Python3.13t wheels, but it seems that the PR failed to complete several tests for other OS.

Does anyone know a way to try opencv with python 3.13t at this moment? There is current support for numpy, scipy, pytorch and other relevant modules.
