Hi @DevPhamPham
This is because yor compiled hef has in built nms from Hailo whereas the json specifies DeGirum’s postprocessor. You can follow the json from this model that can use Hailo’s built-in nms: DeGirum AI Hub. Please let me know if you need more help. We published a detailed guide about this: User Guide 3: Simplifying Object Detection on a Hailo Device Using DeGirum PySDK - Guides - Hailo Community
