Common issues

Describe the bug
I'd like to add roboticstoolbox to a project already using NumPy 2.x. However, it seems rbt depends on NumPy 1.x. Is there a way to upgrade this dependency?

Version information

Did you install from PyPI or GitHub? Github
If PyPI what version number?
If GitHub what commit hash? 2a8111b

Robotics Toolbox depends heavily on two other packages: Swift (3D graphics) and SpatialMath toolbox (underpinning maths utilities). If you think your issue is related to these, then please answer the questions above for them.

To Reproduce

I tried creating a fresh environment and installing roboticstoolbox-python with pip still fails to work. That is, it installs just fine, but won't run because of this NumPy conflict (I'm assuming one of its dependencies is pulling in 2.x).

This problem existed before in #324. It seems that roboticstoolbox has no max numpy version. I did the following to fix it:

python -m pip uninstall numpy
python -m pip install numpy==1.26.4

Thanks. What exactly is causing roboticstoolbox to rely on this ancient numpy version (as well as an ancient matplotlib)?
