Evaluation problem on zero-shot COCO dataset

Open Harry-zzh opened this issue 1 year ago • 3 comments

Thank you for your excellent work. But I have one question about evaluation.

When I run evaluation on COCO dataset for zero-shot setting, I found that if I set the DATASET.TEST to "coco_2017_test_stuff_sem_seg", I got the results: "miou-base": 37.7 "miou-unbase" 36.8 It seems to be normal.

But when I set the DATASET.TEST to "coco_2017_test_stuff_base_sem_seg" and "coco_2017_test_stuff_novel_sem_seg" respectively, I got the results: "miou": 30.8 (for base) "miou": 66.0 (for novel)

I wonder why this weird variation exists, thanks!

Hello, have you solved this question? I have the same question. In general, the result of "coco_2017_test_stuff_base_sem_seg" should be higher than "miou-base". Do you know the reason behind this strange phenomenon? Thank you so much.

Sorry, I haven't solved it yet.

Sorry for late reply. I have forgot the details of the code and I have no idea why it happened. If you found any possible errors that may cause the problem, please tell me or open a pull request. Thanks very much.
