i found rpn_loss_box has always been zero, and that because bbox_outside_weights is 0. maybe i should change positive_weights = 1.0 / num_examples negative_weights = 1.0 / num_examples to positive_weights = 1.0 / num_examples.item() negative_weights = 1.0 / num_examples.item() in anchor_target_layer_fpn.py line 136
