I reinstall ros-kinetic-desktop-full, it solves this problem, but the launch file could not run rightly, the error [trafficlight-2] process has died [pid 2825, exit code -9, cmd /home/nvidia/catkin_workspace/devel/lib/darknet_ros/darknet_ros __name:=trafficlight __log:=/home/nvidia/.ros/log/6e7969ee-058a-11e8-bd57-00044b8c670d/trafficlight-2.log]. log file: /home/nvidia/.ros/log/6e7969ee-058a-11e8-bd57-00044b8c670d/trafficlight-2*.log @mbjelonic So do you have any idea about this, by the way, I can run another launch file normally,the difference between this two launch files is cfg & weights file.
