I'm trying to use rviz to view the pointcloud made by the seeker. I'm using these instructions: https://docs.modalai.com/seeker-user-guide-vio/

Upon running roslaunch voxl_mpa_to_ros voxl_mpa_to_ros.launch, I get this output:

... logging to /home/root/.ros/log/7c7e0f0e-1dda-11b2-a220-18473db1c84b/roslaunch-apq8096-21073.log
