Can't optimize the trajectory

[QinManting]

Hi Sir,
I am trying to run this programme on my computer. But after I input these two lines of commands into two different terminal, I encouter a segmentation fault during the trajectory optimization period. And I use backward_ros to get this detial backtrace. How can I solve the problem?
Thanks.

Commands:
~/marsupial_ws$ roslaunch marsupial_optimizer planner_and_optimizer.launch scenario_number:=2 num_pos_initial:=2
~/marsupial_ws/src/marsupial_optimizer/script$ bash goal_stage_2.sh
