There are some common issues which may be encountered while using the toolbox.

The toolbox is still in beta stage and thus has frequent and often breaking changes. We follow theSemantic Versioning guidlines.

You can update the toolbox:pip install --upgrade roboticstoolbox-python and this should updatespatialmath-python andswift as required.

If the toolbox is installed from Github, you are also required to installSwift,Spatial Geometry andSpatial Math from Github and not PyPI.

If you update the toolbox throughgit pull and reinstall (if not using an interactive install) you will also need to use the Github version ofSwift,Spatial Geometry andSpatial Math and pull the latest changes (and reinstall if required) from those.

Due to the C extensions built into the toolbox and Swift, if the C extensions have been modified, you will need to reinstall the corresponding package to rebuild the C extension. This is required even if you did an interactive install.

When in doubt, dopip install . when you are located in the top level directory of the package. This will uninstall the package if installed, and then reinstall it. Usepip install -e . to do an interactive install/reinstall. Note that you may need to do this for the toolbox as well as for Swift.
