Hi, We use this method to deploy yolov4 in DS5.0, fp16 engine can work successfully but int8 engine can not display object bbox.
we run:
trtexec --onnx=yolov4_1_3_512_320.onnx --explicitBatch --saveEngine=yolov4_1_3_320_512_fp16.engine --int8

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Have you run the engine well using TensorRT in int8 mode without DS?
