Dear maintainers,
When I use the smach_viewer on Ubuntu 22.04 and ROS-O, I met this error:
File "/opt/ros/one/lib/python3/dist-packages/smach_viewer/smach_viewer_base.py", line 75, in _load_local_data local_data = pickle.loads( _pickle.UnpicklingError: pickle data was truncatedSo I did some change to make it work.
The change has been tested on Ubuntu 22.04 with ROS-O and Ubuntu 20.04 with ROS Noetic. The tested command is
rosrun smach_viewer smach_viewer.pyThank you for the maintenance!
