I'm trying to get smach_viewer to work on Ubuntu 18.04 using ROS Melodic, and I'm spinning endlessly down the python module import spiral! :)

I'm wondering if there are some directions online how to get smach_viewer to work?

So far I've done the following:

Used pip to install:

pyyaml
rospkg

Used apt to install

ros-melodic-smach-viewer
python-wxgtk3.0
python-gobject
python-gtk2

I'm now stuck at this error saying:

$rosrun smach_viewer smach_viewer.py
wxversion 2.8 is not installed, installed versions are ['3.0-gtk3']
wxversion 2.8 is not installed, installed versions are ['3.0-gtk3']

(smach_viewer.py:11503): GLib-GObject-WARNING **: 01:50:46.763: cannot register existing type 'GdkDisplayManager'

(smach_viewer.py:11503): GLib-CRITICAL **: 01:50:46.763: g_once_init_leave: assertion 'result != 0' failed

(smach_viewer.py:11503): GLib-GObject-CRITICAL **: 01:50:46.763: g_object_new_with_properties: assertion 'G_TYPE_IS_OBJECT (object_type)' failed

Now I'm not sure if I've installed the right packages, but I managed to get past all the import statements :) Anyone ot a clue how to get the smach_viewer working?

regards Frimann

Some time ago we also wanted to use smach and the viewer, but it resulted in implementing our own viewer as the smach viewer had to many problems. Now, we completely switched to flexbe (http://wiki.ros.org/flexbe) wich is the way to got in my opinion. It is also based on smach, has a nice viewer and is under active development.
