Run on own rosbag data

[manishsaini0901]

Describe the bug
I am trying to run it using my own recorded rosbag having image, imu, and event camera topics. Still, as I try to run it using bare minimum configuration, it shows the following error.

To Reproduce
Steps to reproduce the behavior:

1. Edit "vio_davis.conf" to change topic names as
   --topic_cam0=/uav3/ximea_camera_down/image_raw
   --topic_dvs0=/uav3/events
   --topic_imu0=/uav3/imu
2. Roslaunch with self recorded rosbag using the command as given in next point.
3. roslaunch ze_vio_ceres ijrr17_events_only.launch bag_filename:=event.bag

Rosbag info:

             /uav3/ximea_camera_down/image_raw    2293 msgs    : sensor_msgs/Image

Expected behavior
It shows the error:
