Failed to create tensorrt engine from QAT onnx model


I am debuging QAT with pytorch_quantization(TensorRT/tools/pytorch-quantization at main · NVIDIA/TensorRT · GitHub).
The onnx model with QDQ from pth can be convertered successfully.
But when i am trying to convert the simple ONNX model to TensorRT, it failed.

Jetpack Version : 5.0.2-b231
TensorRT Version : 8.4.1
CUDA Version : 11.4
CUDNN Version : 8.4.1
Operating System + Version : ubuntu20.04
Python Version (if applicable) : 3.8.10
PyTorch Version (if applicable): 1.10

Please try on the latest TensorRT version 8.5.2 and let us know if you still face this issue. We are moving this post to the Jetson AGX Orin forum if you need further help.

Thank you.

@ spolisetty
it works on the TensorRT version 8.5.1(I build the tensorrt engine with docker:

Can you explain more about this error?

Another question:
How to upgrade the tensorrt version from 8.4.1 to 8.5.1(or 8.5.2) on orin.
