So I don't always get this error when I run smach_viewer but it occurs about 50% of the time I run it. Is it a bug with smach_viewer or perhaps my code?

Error output

wxversion 2.8 is not installed, installed versions are ['3.0-gtk2']

What happens next? The smach_viewer window, which still shows the state machine, fades into a grayish color and an empty dot_viewer window pops up.

I have the same issue. I have tested all of my state transitions and it all checks out. I can't find any error in my code other than a python warning about expecting a list instead of a Dict in my concurrent state declaration. I am suspicious it is related to the concurrent state and possibly the outcome map or default transition.

Do you have a concurrent state in your smach state machine?

Did you ever resolve this issue?

Cheers Alex
