Then i tried other launch files, it is much like the same

Looking forward to your help. THANKS
Hi @YangSiri ,
If you are using self-built g2o library, try libg2o debian package instead: sudo apt install ros-melodic-libg2o
This thread could help you: https://github.com/koide3/hdl_graph_slam/issues/4
Thanks, @koide3
My environment is ubuntu16.04 kinetic. Will the libg2o you mentioned conflict with my source-built g2o?
It may conflict with your g2o. If you don't like it, you can give the docker image a try: https://github.com/koide3/hdl_graph_slam#hdl_graph_slam-in-docker
