Run roslaunch but no result ?

[liming0791]

I modified config file and run roslaunch ORB_VIO testeuroc.launch ，then I play a bag，no VIO log or any result show. Only log below :

... logging to /home/liming/.ros/log/14c9cb86-6bb6-11e8-b487-e4a7a0c3f334/roslaunch-liming-Aero-14-8948.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.

started roslaunch server http://liming-Aero-14:39313/

started core service [/rosout]

I'm sure I have changed "test.InitVIOTmpPath" and "bagfile" in config file.

Don't know what is wrong ?
