Describe the bug

I try to use the toolbox, installed it via pip on my DOCKER Container but the following error appears when i try to work with.

import roboticstoolbox /usr/local/lib/python3.10/dist-packages/matplotlib/projections/init.py:63: UserWarning: Unable to import Axes3D. This may be due to multiple versions of Matplotlib being installed (e.g. as a system package and as a pip package).

Version information

Did you install from PyPI or GitHub? If PyPI what version number? roboticstoolbox-python==1.1.0 (but tried all the newer ones also) spatialmath-python==1.1.8 (but tried all the newer ones also )

Environment (please complete the following information): Ubuntu 22.04 Docker Container ( FROM osrf/ros:humble-desktop) Python 3.10.12

[peteflorence]

If not using graphics, a hacky workaround is to just not import that line, i.e. in OP's example:

vi /usr/local/lib/python3.10/dist-packages/spatialmath/base/transforms3d.py

and comment out line 48
