Describe the bug
We are encountering an issue in GLASS where in Python >3.12 we're getting

TypeError: only 0-dimensional arrays can be converted to Python scalars
This appears to have come from a change in NumPy 2.4.0. This is only appearing in later Python versions because NumPy 2.5.0 because it drops support for Python 3.11.
To Reproduce
Passes
uv run --isolated --with "camb" --with "numpy==2.3.5" python -c "import camb; camb.set_params(H0=70)"
Fails
uv run --isolated --with "camb" --with "numpy==2.4.1" python -c "import camb; camb.set_params(H0=70)"
(2.4.0 release was yanked due to backwards compatibility issues)
