A-LOAM Cannot locate nodes in the package

[Ab-Tx]

Hello. I've cloned A-LOAM repo and built the workspace with catkin_make without any errors.

When run any of the launch files I get the following message:

$ roslaunch aloam_velodyne aloam_velodyne_VLP_16.launch 
... logging to /home/ab/.ros/log/deff0074-ef50-11ed-aa11-d8cb8ac6cb82/roslaunch-u18lled-6322.log

Is this a known issue on ROS melodic? I'm using ubuntu 18.04.6

Closing since this is a workspace issue and not a A-LOAM issue.
