Note: This error originates from the build backend, and is likely not a problem with poetry but with opencv-python (4.10.0.84) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "opencv-python (==4.10.0.84)"'.

make[1]: *** [install-python-dependencies] Error 1
make: *** [build] Error 2

I'm actually not sure if we need opencv-python at all in our repo, so I think it might be worth attempting to remove this dependency and run INSTALL_DOCKER=0 make build to see if the project still builds. If it does, we can just remove the dependency. Otherwise, we will need to take some other course of action, such as pinning opencv-python to a working version.

Duplicate of #6045.

Was this fixed though? I don't see it on my Mac. Wondering if there is a specific environment thing here.
