bbox_loss
is only for fg rois, and at the beginning when RPN is not well trained there are not many fg rois.

bbox_loss
is only for fg rois, and at the beginning when RPN is not well trained there are not many fg rois.
So do you mean the loss is calculated among the fg rois but averaged between all the fg and bg rois?
