A new problem I have encountered when running this program seems that the ground-truth-3D-sensor of ego car in lgsvl simulator cannot sense pedestrians controlled by waypoint, which will not exist in random traffic mode. But I saw the experimental video. It seems that pedestrians can be sensed. How can this problem be solved.
It seems that someone in lgsvl's official GitHub has reported this problem"lgsvl/simulator#1797", but because lgsvl will go sunset soon, the official can't fix this bug at present.
