Hi, I am working with RepVGG classification network recently, and I want to integrate the classification model as a secondary GIE in DeepStream. The pipeline I am using is a primary GIE for person detection, and a secondary GIE to classify whether the person is smoking. I converted the original Re…

@bcao Could you please give me some advice?

Hey customer, can you try to deploy the engine generated via tensorRT to deepstream and see if it can work well?

@bcao Thanks for the quick reply. I used tensorRT engine file in both methods, and I think the prepocess methods are the same which only includes resize and division by 255. But the tensorrt predicted result I got from deepstream is much worse than tensorRT python api

Secondary-GIE result in DeepStream messed, python tensorrt api works fine

You can refer DeepStream SDK FAQ - #9 by mchi to dump the inference input and see if there are any differences?
