typing glitches?

[PhilFreeman]

Installed everything with pip install rvc3python When I run ~/.local/bin/rvctool I get the following:

phil@Office:~$ ~/.local/bin/rvctool 
Traceback (most recent call last):

TypeError: 'numpy._DTypeMeta' object is not subscriptable

Which, looking at the other issues, looks like it may be more typing challenges. Python is v. 3.10.12, OS is Ubuntu 22.04.3 LTS

Hi @PhilFreeman , sorry for the late response.

Could you please try again (e.g. pip install --upgrade rvc3python)?

We actually just pushed a new release for spatialmath today. I tried your sequence just now and it seems to be working

# i started with a fresh environment for this test
pip install rvc3python
rvctool

Yup! Set up a venv and did a clean pip install. Worked just as you show. Seems to have fixed the issue.
