I build from the source code successly,but when I run : $roslaunch grid_map_demos simple_demo.launch It shows: ERROR: cannot launch node of type [grid_map_demos/simple_demo]: can't locate node [simple_demo] in package [grid_map_demos] ERROR: cannot launch node of type [grid_map_visualization/grid_map_visualization]: can't locate node [grid_map_visualization] in package [grid_map_visualization] process[rviz-4]: started with pid [27004] [ERROR] [1510757591.418195526]: PluginlibFactory: The plugin for class 'grid_map_rviz_plugin/GridMap' failed to load.

Make sure the plugin description XML file has the correct name of the library and that the library actually exists.

Did you solve this?

Just form the errors, I would guess you need to resource the setup.bash file in our devel folder after building for the first time.

catkin_make --only-pkg-with-deps grid_map_demos
catkin_make --only-pkg-with-deps grid_map_visualization
catkin_make --only-pkg-with-deps grid_map_rviz_plugin

You just need to change the path of the dataset. And dont forget to source the bash file
