After launching the custom launch file, I get this error/warning message

[ WARN] [1519091710.713342852]: /rtabmap/rtabmap: Did not receive data since 5 seconds! Make sure the input topics are published ("$ rostopic hz my_topic") and the timestamps in their header are set. If topics are coming from different computers, make sure the clocks of the computers are synchronized ("ntpdate"). If topics are not published at the same rate, you could increase "queue_size" parameter (current=10).
/rtabmap/rtabmap subscribed to (approx sync):
   /rtabmap/odom,
   /camera1/rgbd_image,
   /camera2/rgbd_image

I've ran rtpdate on the master computer and on two of the RPI so I don't think its a sync issue with the time stamps. I've already run rostopic hz on
   /rtabmap/odom
   /camera1/rgbd_image
   /camera2/rgbd_image

And they all say "does not appear to be published yet"

I appreciate the continuous help!
