WebNov 14, 2024 · gIoU is currently supported as torchvision.ops.generalized_box_iou (this name was kept for DeTR compatibility) and I guess creating loss function from the op is straightforward? I think it is 1 - ops.generalized_box_iou? For loss functions there is an RFC #2980 and I guess gIoU loss is proposed there.
