numpy version issue between opencv and picamera2
Looks like picamera2 wants numpy < 2.x while opencv 4.11 requires numpy >2.x. Good news is that everything seems to work just fine running 1.24.2 (the base installation). Issues arise if you go ahead and install opencv into the owl virtual environment, it causes a clash that breaks picamera2.
It appears as a very not clear value error where video source 0 is not able to be found.
This will be fixed shortly through an updated installation script.
Yes, I realised this appeared because the latest opencv-contrib-python 4.12.x released a couple of weeks ago now requires numpy>2.x. So if you install opencv-contrib-python==4.10.0.84, this will fix it.
My fault for not pinning package versions and learning the hard way...I am updating this in the wireless-display branch.
But if you are having this issue, just run pip install opencv-contrib-python==4.10.0.84 and pip install numpy==1.24.2 within the owl virtual environment. If you have the latest opencv already install pip will complain with the downgrade, but the latest version of opencv does seem to work just fine with numpy 1.24.2.
