Alpha-IoU losses can be configured in Line 131 of utils/loss.py, functionesd as 'bbox_alpha_iou'. The alpha values and types of losses (e.g., IoU, GIoU, DIoU, CIoU) can be selected in this function, which are defined in utils/general.py. Note that we should use a small constant epsilon to avoid torch.pow(0, alpha) or denominator=0.
