[rgbd_leg_detector.launch] requires the 'bag' arg to be set

[aminemh1]

I try to run this command roslaunch flobot_tracker_bringup flobot_tracker.launch, I have this problem

[catkin_ws/src/FLOBOT/rgbd_leg_detector/launch/rgbd_leg_detector.launch] requires the 'bag' arg to be set
The traceback for the exception was written to the log file

Did you give 'bag' a default value?
