what is the meaning of num_instance_classes #56

Closed iris0329 closed 5 months ago

iris0329 commented 6 months ago

for s3dis dataset, num_semantic_classes is same as num_instance_classes; However, for scannet200, num_instance_classes is 198, and num_semantic_classes is 200. Can I just set num_instance_classes to 200? what's the difference?

There are 2 classes in ScanNet that don't participate in instance segmentation: floor and wall. However for S3DIS all 13 classes are both in instance and semantic benchmarks.
