About your coco id and labels #42

I noticed that you make the categories sorted as 0-52:stuff,53-132:things in creating panoptic_coco_categories_stff.json. Why you do this change?

So when you print out the result matrix like this format:

IDX | PQ SQ RQ IoU TP FP FN

Does theIDX 0 mean the result for the first thing class or the first stuff class? Similarly, how about other metrics like the Mean and per-category AP? The first line represent the first thing class or first stuff class?

I really appreciate your reply.

We change class order in order to make it consistent with cityscapes (stuff first, then things). And all results follow the setting (so IDX 0 means the first stuff class). AP is only for things so the first line is for the first thing class. If you want to submit test-dev result you need to do some change on prediction.
