trained pt files convert pre_post_processing.onnx file Predict no result

[FengYanNMG]

The pre_post_processing.onnx files obtained by converting yolo11n.pt or yolov8n.pt with yoloe2e can be used correctly, but the pt files trained by me with data sets cannot Detection objects correctly after conversion, and the converted ONNX files can also be predicted. But the pre_post_processing.onnx file has no result

I'm sure there's something wrong with my model, but I don't know where the problem lies.
