had to downgrade numpy from 2.0.0 to 1.26.4 to make cadquery work

[MotoCyti]

new install of cadquery on windows 10. Cadquery version 2.4.0
using python 3.12.4
test of install with "import cadquery" produced an error: AttributeError: module 'numpy' has no attribute 'bool8'. Did you mean: 'bool'
google search returned that latest numpy no longer has bool8.
So I downgraded numpy from 2.0.0 to 1.26.4
It solve the problem. basic cadquery test passed.

#1617 did not fix the issue for me, there is still a problem with numpy2:

/opt/hostedtoolcache/Python/3.11.9/x64/lib/python3.11/site-packages/cadquery/occ_impl/sketch_solver.py:10: in
import nlopt
/opt/hostedtoolcache/Python/3.11.9/x64/lib/python3.11/site-packages/nlopt/init.py:1: in
from .nlopt import *
/opt/hostedtoolcache/Python/3.11.9/x64/lib/python3.11/site-packages/nlopt/nlopt.py:20: in
from . import _nlopt
E ImportError: numpy.core.multiarray failed to import
------------------------------- Captured stderr --------------------------------

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

How did you install? Via pip or conda?

[drayde]

Pip.

Then I think you need to ask the maintainers of nlopt to build against numpy 2 and release.

[drayde]

Yes, I think you are right. I'll use numpy<2 for now
