Dear.
I am in trouble.  It around me two weeks.  I have a project that uses Yolov4 in pytorch for the Deepstream. So the yolo model should transform to ONNX, then Engine file by TensorRT.
But I want add some  preprocessing for yolov4 model, then transform the preprocessing and yolo model to ONNX together.  I don’t know how to do that.
Actually,  I try to modify the YoloV4 code and hope to add a preprocess before the yolov4 model. But I get the error
“torch.nn.modules.module.ModuleAttributeError: ‘Darknet’ object has no attribute ‘myPreProcessing’”
So I want to build the preprocess model and make the two model serially.
Please help me. Thank you very much.
