For example, I can run the traffic detection model’s engine file in TensorRT and get following results. But how to interpret the outputs? where can I find the definition of the outputs? I didn’t see such explanation/descriptions in NGC model zoo/card:
In the trafficDetect model, this is what I am getting:
binding: input_1
kFLOAT
dims: 3 x 368 x 640
vol: 706560, elementSize: 4, allocationSize: 2826240
binding: conv2d_bbox
kFLOAT
dims: 16 x 23 x 40
vol: 14720, elementSize: 4, allocationSize: 58880
binding: conv2d_cov/Sigmoid
kFLOAT
dims: 4 x 23 x 40
vol: 3680, elementSize: 4, allocationSize: 14720
Again, it’s not clear what the output represents. This is what the output looks like with one image with a few cars:
