Numpy incompatibility issues

[scottbarnesg]

There seems to be a compatibility issue between numpy dependencies in the picamera2 and opencv packages. When installing the streamer on a raspberry pi, I get the following error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
opencv-python-headless 4.12.0.88 requires numpy<2.3.0,>=2; python_version >= "3.9", but you have numpy 1.24.2 which is incompatible.

However, if I upgrade numpy, I get a different error when running streamer.py:
