I try to follow this tutorial ( )

first i run roscore after that i run "rosmake gmapping", i also did "rosparam set use_sim_time true"...

then i run "rosrun gmapping slam_gmapping scan:=base_scan _odom_frame:=odom_combined" nothings happen so in a new terminal i run the command "rosbag play --clock basic_localization_stage.bag" (which i downloaded by wget ). It is still playing while i writing this question.

but in the gmapping terminal, warns are shown: WARN [1465547193.039340608, 49.686203634]: MessageFilter [target=odom_combined ]: Dropped 100.00% of messages so far. Please turn the [ros.gmapping.message_notifier] rosconsole logger to DEBUG for more information.

i think i'm following the tutorial right, but dont know what is the problem

update: now that i do the tutorial like the same way above, just* this time those warns arent shown.

But when the bag is playing, i want to watch the progress in rviz. after i run rviz, i add map in rviz. and set the topic : topic /map like the tutorial said, but in rviz there is something wrong. my sceenshot of rviz:

update2: i really dont know whats going on? again i did the same things and again there are the warnings again (like the original version of my question)
