Hello, I also have the same issue but I am unable to change the source code since the topic is coming from an android app ( Source code should be fro here: and might even be fixed (imu frame_id is published as "/imu") but I don't have the toolchain to recompile. Thanks

What if you remove the '/' in your source code? Sometimes ROS will add a '/' for you, so if you give '/kitti_player', things will go wrong. So just give 'kitti_player' in your code.
