04_path_planning gives segmentation fault in AirGen - Neighborhood

[omkarpatil18]

I start the Neighborhood environment in a terminal with bash run.sh. In a different terminal I run python 04_path_planning.py. This results in the below error-

Please let me know if I'm doing something foolish. Thanks for your help!

P.S. I tried to run it in the oil-rig environment and it worked. But I'd still like to work with the Neighborhood environment. Thanks
