I used the trained last.ptht to debug.The dimension of the parameter "rel_scores" is n * 57. Why is the maximum number of each row in the first column, that is, the relationship is the first category, "background"? (I mean why it is detected that the relationship between object pairs is "background" before backpropagation in the training phase, Instead of corresponding other relationships? Or most of the object pair relationships are "background" Do you lose with GT?)
I mean before backpropagation，why thehe relationship of triples in a detected result is the category "0"?：
