pyexotica import error due to missing libmoveit_rdf_loader

I noticed this error being thrown several times recently.

Traceback (most recent call last):
  File "/home/chris/catkin_ws/devel/lib/ik_ros/ik_node.py", line 15, in <module>
    exec(compile(fh.read(), python_script, 'exec'), context)

ImportError: libmoveit_rdf_loader.so.1.1.7: cannot open shared object file: No such file or directory

The only fix I've found is to clean and rebuild my catkin workspace from scratch - not ideal!

Any ideas?

This is likely because you ran apt-get upgrade and the new MoveIt version is 1.1.8, but you've linked against 1.1.7. You can check your installed MoveIt version with dpkg-query -l ros-noetic-moveit-ros-planning.

Sounds about right, will close for now and reopen if issue persists. Thanks @wxmerkt!
