terminate called after throwing an instance of 'rosbag::BagIOException' what(): Error opening file: [closed]

edit

I would like to run ORB_SLAM with my own drone. when typing roslaunch SLAM SLAM.launchin the terminal, I got an error that has never seen before as follows:

process[SLAM-1]: started with pid [13284]
terminate called after throwing an instance of 'rosbag::BagIOException'
  what():  Error opening file: 
[SLAM-1] process has died [pid 13284, exit code -6, cmd /home/htf/orb_ws/src/SLAM/bin/SLAM /home/htf/orb_ws/src/SLAM/Data/ORBvoc.txt /home/htf/orb_ws/src/SLAM/Data/Drone.yaml __name:=SLAM __log:=/home/htf/.ros/log/b3cdf97a-c6ef-11e8-bd1c-80a589d234a5/SLAM-1.log].

all processes on machine have died, roslaunch will exit
shutting down processing monitor...
... shutting down processing monitor complete

here is the launch file:

<launch>
  <node name="SLAM" pkg="SLAM" type="SLAM" args="/home/htf/orb_ws/src/SLAM/Data/ORBvoc.txt /home/htf/orb_ws/src/SLAM/Data/Drone.yaml"/>

</launch>

does anyone know how to fix it? thanks a lot.
