Describe the bug and reproduction steps

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)"'.

I was following instructions from https://github.com/All-Hands-AI/OpenHands/blob/main/Development.md

The error happens at Step 2. "make build".

Looks like manually installing it got through the error?

poetry run pip install "opencv-python==4.10.0.84"

[chunhualiao]

Yes.
