Hi, I installed kineverse and kineverse_msgs successfully and was able to build kineverse_experiment_world

However when I try to run the example rosrun kineverse_experiment_world all_kinematics.py I get the following error:

(kineverse) russell@robot-System-Product-Name:~$ rosrun kineverse_experiment_world all_kinematics.py

Hi,

I have investigated the issue and fixed it. It was caused by a partial refactoring which I did long ago. The current master of this repository and the master of Kineverse should work together now.
