Numpy 2.x Importing Error

[hilookas]

pybullet build time: Nov 28 2023 23:45:17

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.1 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.

AttributeError: _ARRAY_API not found

    import pybullet as p
ImportError: numpy.core.multiarray failed to import

Minimal reproducible example:

pip install -U numpy
pip install -U pybullet

import numpy
import pybullet

@erwincoumans I could build pybullet with numpy 2.0 locally without any problem (but I didn't find the many linux wheel builder script to share a pre-built wheel with others)

For the others, if you want to use pybullet with numpy 2, you can do pip install git+https://github.com/bulletphysics/bullet3 to build from source.

@erwincoumans so I guess its just a matter of building a new wheel for pypi?
