Why the pretrained VCOCO model has 81 object classes?

[weiyunfei]

When I tried to evaluate the VCOCO model you provide, I have to set the parameter --num_obj_classes to 81. What is the reason for this setting? And should I set --num_obj_classes 81 during training?

Thanks for your reply!

I've checked the code, I found that the VCOCO model you released has an 82-way object head. I just wanner verify whether it is a technical error.

Thank you for pointing it out. The correct number is 81. The number of object classes in the training command for V-COCO, which was 80, was incorrect, and I fixed it to 81. The one additional class is for the missing object case in the V-COCO dataset, where a person is acting, but a target object is missing.
