Hello, when i do the second roslaunch, there is ERROR: cannot launch node of type [hector_trajectory_server/hector_trajectory_server]: hector_trajectory_server ROS path [0]=/opt/ros/kinetic/share/ros ROS path [1]=/media/lvsijie/mypassport/linux/catkin_ws_iscloam/src ROS path [2]=/opt/ros/kinetic/share my system is ubuntu 16.04, it seems that there is no hector_trajectory_server. Do i install hector-slam to get hector_trajectory_server? thank you!

Yes you are right, for trajectory visualization you have to install sudo apt-get install ros-melodic-hector-trajectory-server The readme is updated for the above problem
