I was trying to install via: python3.11 -m pip install qml@git+https://github.com/qmlcode/qml@a7921c9176b9498dcce096efad0883271706d633

The venv does have numpy-1.23.4 installed.

The build functionality from numpy/setup tools has been deprecated. A new version of the core QML library is currently under development https://github.com/qmlcode/qmllib. Some work is still needed, but the core functions (not parallel yet) do work.
