How to resolve it?

[Zzh-tju]

You just replace loss functions in specific place. Nothing else needs to be changed.

@Zzh-tju Please elaborate. I am not able to fix it .

[Zzh-tju]

If you are asking about a specific project, please forgive me for not being able to help. This repo only provides the code in our paper as an example of usage.

For any other detection pipelines, D/CIoU loss can be an alternative for bbox regression loss. And Cluster-NMS along with its variants for post-processing.

best regards

I have solved the issue. Thanks for replying 👍
