How to use pedsim?

[aghorbani96]

I'm researching pedestrian dynamics and I'm new with ROS & Rviz, when I execute the launch file(e.g simple_pedestrians.launch) I encounter the empty Rviz window with no object. I would be grateful if you help me with how to use pedsim. (preferably with a sample example)

Thanks

What versions of ROS, ubuntu are you using?

Can you share the output of compiling the packages successfully. It seems that you have not build all the packages
