3 years ago Hi, I met the same problem. Then I check the kittiHelp.cpp and set the correct path of my dataset in the launch file. Pay attention, the path should end with a '/' to show it is a folder not a file. Example:
Another way to check if it is your path is correct is to cout the path string in the source code of 'kittiHelp.cpp' in case of ant misspelling. Hope it will help you.

Now I am trying to test A-LOAM on kitti (velodyne laser data, 80 GB), as far as I know, we should try to transform them into ROS bag at first. (if it is not true, please point it out).
When I use the
kitti_helper.launch, the output is only a .bag file about 4kB in total.This is the terminal information: `... logging to /home/objloc/.ros/log/c787383e-8951-11ea-b5c0-9cebe8b95aff/roslaunch-deeplearning-12255.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
