Thank you for reporting the issue!
I have not tested it on Ubuntu 20.04.

[iwatake]

The new version with bug fix has been released, and confirmed on Ubuntu 20.04 as well.
pip3 install rotop==1.0.4

However, the following command to upgrade dependent library is still needed.
pip3 install numpy -U

Phenomenal - Thanks - Got a new Create3 (ROS 2) robot that recommended Galactic/U20.04 so I started there.
