Using trtexec to convert yolov3.onnx into int8, fp16, engine in jetson-nx deepstream has the same effect, and the detection accuracy is completely wrong

sudo ./trtexec --onnx=./yolov3-416.onnx --batch=1 --workspace=1024 --int8 --calib=./calib_yolov3-416.cache --saveEngine=./yolov3-416-gpu.engine --verbose=True

The command you shared is for TensorRT.
Did you get the correct result with TensorRT?

This information can help to distinguish the cause is from Deepstream or TensorRT.
