roslaunch dvrk_gazebo psm_gazebo.launch Error

[francomomo]

Hello!

I have the following error when running roslaunch dvrk_gazebo psm_gazebo.launch

I am trying to run this in Ubuntu 20.04 on parallels on Macbook w/ M1 chip.

Do you guys have any idea on what might went wrong?

This may be too late for you but for people who might see this the command should be command="$(find xacro)/xacro '$(find dvrk_description)/psm/psm_launch.sdf'"/> removing the ".py" this is a change in noetic REF: http://wiki.ros.org/xacro
