room_segmentation_algorithm:4 can not run about ipa_coverage_planning

[ipa-rmb]

Does this happen with a specific map or with every map?

It happened with every map. Moreover, I have tried to run it on a new computer with Ubuntu 18.04, ROS Melodic. The program still crashed. The program in the Melodic provided more error information when it crashed.
In addition, I want to explain that since I only need to segment the rooms of the maps, I only use and compile two ROS packages, "ipa_room_segmentation" and "ipa_building_msgs". I installed the dependencies using "sudo apt-get install ros-kinetic-XXX", such as opengm, libdlib, etc.
The server output the following contents on the new computer with Melodic.
