ROS melodic运行urdf模型时碰到，
[ WARN] [1645792286.082081404]: The 'state_publisher' executable is deprecated. Please use 'robot_state_publisher' instead
[WARN] [1645792286.343040]: The 'use_gui' parameter was specified, which is deprecated. We'll attempt to find and run the GUI, but if this fails you should install the 'joint_state_publisher_gui' package instead and run that. This backwards compatibility option will be removed in Noetic.
