Questions about the Loss for verbs. #15

Thanks for your contribution to HOI, which inspires and enlightens me. However, as I am reading your work, I raise a question that I can not explain. When you calculate losses for all the queries, you set those unmatched queries' object labels as self.num_obj_classes, which is reasonable. But you set those unmatched queries' verb labels as zeros, which is a bit unreasonable. Any reasons for that? Please enlighten me.
