The validation sequence of semantic-kitti has only 5 points labeled as motorcyclist, therefore it cannot distinguish them as a motorcyclist, obtaining a 0% IoU score. The same issue happens with the other-ground class.

If you run in on test and upload results to the benchmark server, you will see it indeed learns those classes.
