Seems duplicated with Error Code 1: Myelin (Division by 0 detected in the shape graph. Tensor (Divisor) “sp__mye3” is equal to 0.; ) - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums.

Please use “trtexec” tool to generate the TensorRT engine first.

trtexec --onnx=yolov8s-seg.onnx --saveEngine=model.engine --fp16 --verbose.

It return error

When above error came, model.engine save in directory. We run the model.enginer and it return again same error
