I read the smach tutorial and there is no problem until I run smach_viewer command.
rosrun smach_viewer smach_viewer.py
The terminal shows the below error :
[rospack] Error: package 'smach_viewer' not found
I checked the /opt/ros/noetic/share path there is no smach_viewer package. just smach. the question is: What should I do to see the graphical representation of my smach code?
I'm using ubuntu focal, Noetic ROS, and python3. thanks a lot for your support.
