DeepStream 7.0 only support Jetpack 6.0. I think you need to re-burn the Jetpack. JP-6.1 is prepared for the next version.

junshengy Thanks very much X 100 .
There is new information to solve this problem, but I am very happy。

[abuabuliu]

could you tell me where is the engine “resnet18_trafficcamnet.etlt_b1_gpu0_int8.engine”
because the new question is

WARNING: Deserialize engine failed because file path: /opt/nvidia/deepstream/deepstream-7.0/samples/models/Primary_Detector/resnet18_trafficcamnet.etlt_b1_gpu0_int8.engine open error

thanks
