Thanks in advanced. I update source1_csi_dec_infer_resnet_int8.txt ‘model-engine-file=…/…/models/Primary_Detector/resnet10.caffemodel_b1_fp16.engine’ and run:

nvidia@nvidia-desktop:/opt/nvidia/deepstream/deepstream-4.0/sources/objectDetector_Yolo$ deepstream-app -c ../../samples/configs/deepstream-app/source1_csi_dec_infer_resnet_int8.txt

Excuse me, I use nano, so I’m not sure which area is more suitable.
