Can you tell how to solve it?

I run this "roslaunch wpr_simulation wpb_gmapping.launch" every time, there are always some errors like these:

RLException: Invalid tag: Cannot load command parameter [robot_description]: no such command [['/opt/ros/noetic/share/xacro/xacro.py', '/home/ws/catkin_ws/src/wpb_home/wpb_home_bringup/urdf/wpb_home.urdf']].

Param xml is
The traceback for the exception was written to the log file

How to solve it?

Thank you very much!

Hi,
Have you got over the problem? Or you should try the new codes, just updated for noetic :)
