in detr's config, the cls_cost's weight in 'HungarianAssigner' is 0, why? #7

I have heard you: the Hungarian Algorithm needing explicit class information to achieve one-one matching, and the performance is poor if there is no pseudo-semantic labels. so I think the cls_cost is important, but you set it 0, why?

Thank you again, it is a bug when I clean the code. You can see the pre-training config that has been released, it is 1.0. I will update related code
