谢谢！！急求！请问计算tensor(N,5)的两个旋转框的IOU的源码在哪个文件下

[yzk-lab]

你好，我现在在处理IOU，但是在mmdet,core或者bbox下都只看到了处理(N,4）张量的IOU的方法，我想知道在哪里有计算旋转框IOU的代码？这个s2anet项目里是否有提供？谢谢！

thanks for your reply.I have know how to get IOU.there exists another problem.i want to replace the smoothl1loss with iou loss .but i print the bbox_pred and target ,i found the target is a tensor with 0.so the IOU bwtween the target and pred is 0,therefore my iou loss is NAN.if i want to use the iou ,how can i output the iou between the anchor and gt_bbox?i cannot get the IOU between the pred and target.hope for your reply.this problem have puzzle me for a long time.

i used your original s2anet to replace the smooth-L1loss with iou loss .it failed

To use IoU as the loss metrics, I suggest the PIoU loss: https://github.com/clobotics/piou

are there any solution with IOU by your s2anet?

sorry to bother you.can you tell me input parameters (the pred and target )in loss function where i can touch,it seems i can not understand the target why the anchor_target is a tensor only include zero.i need to know the meaning of pred and target.
