motion planning demo failed

Hi, I used docker igibson/igibson-gui:latest to run your example. I tried motion planning demo using two demo scripts:

First script: python motion_planning_example.py -c ../configs/turtlebot_interactive_nav.yaml. Error is Traceback (most recent call last): File "motion_planning_example.py", line 32, in <module> run_example(args) File "motion_planning_example.py", line 12, in run_example motion_planner = MotionPlanningWrapper(nav_env) File "/opt/igibson_new/gibson2/utils/motion_planning_wrapper.py", line 48, in __init__ assert 'occupancy_grid' in self.env.output

Second script: python mouse_interaction.py and click m to change to planning mode. Every time I Left click, error occurs. Error is Traceback (most recent call last): File "/opt/igibson_new/gibson2/render/viewer.py", line 423, in mouse_callback self.planner.set_marker_position_yaw( AttributeError: 'NoneType' object has no attribute 'set_marker_position_yaw' I think the variable of the self.planner is not initialized

Can you help me to fix these two issues? Or are there other ways to run motion planning example?

This commit should make the process even easier.

You only need to run python motion_planning_example.py now.
