Deepstream python app deepstream-test2 change nvinfer to YOLOv3

Hi

I am testing deepstream-test2 and I want to change the model to YOLOv3.

I looked at objectDetection_Yolo and copied the config file config_infer_primary_yoloV3.txt, yolov3.cfg, yolov3.weights, labels.txt, and yolov3-calibration.table.trt7.0 to deepstream-test2.

When I run python3 deepstream_test_3.py. The following error occured. Please help.

i tried using config_infer_primary_yoloV3.txt directly by renaming it and tried just modify the model file as listed below. Both failed

You need to change the corresponding nvinfer config file
