classes

[Yzichen]

Class ids 1-16 represent [barrier', 'bicycle', 'bus', 'car', 'construction_vehicle', 'motorcycle', 'pedestrian', 'traffic_cone', 'trailer', 'truck', 'driveable_surface', 'other_flat', 'sidewalk', 'terrain', 'manmade', 'vegetation], but what do classes 0 and 17 represent?

Sorry for the confusion. Class 17 represents the empty class. Class 0 does not represent anything and would not appear in the GroundTruth, so the model would learn to simply ignore this class.
