moveit_commander_cmdline.py Error

edit

Hey,

I was going through the Moveit tutorials here: Moveit Commander Scripting and when I tried launching rosrun moveit_commander moveit_commander_cmdline.py, I am getting the following error:

kashyap@kashyap-Lenovo-ideapad-320-15IKB:~$ rosrun moveit_commander moveit_commander_cmdline.py
Failed to import pyassimp, see https://github.com/ros-planning/moveit/issues/86 for more info

Could anyone guide me as to what this error means? Thanks
