As the warning is saying, verify that these topics are published:

$ rostopic hz /rtabmap/odom
$ rostopic hz /camera1/rgbd_image
$ rostopic hz /camera2/rgbd_image 

If /camera1/rgbd_image or /camera2/rgbd_image is not published, very that inputs of rgbd_sync are also published.

If /rtabmap/odom is not published, very that inputs of rgbd_odometry are published.

You can use "rosnode info" to see inputs/outputs of a node to debug. I recommend to use "rqt_graph" to see better how all nodes are linked and track some problems.

cheers,
