Myelin error when load ONNX model, Assertion `false && "Invalid size written"' failed


We’re preparing to use Orin with TensorRT8.3 for better performance, but it failed when creating a Builder. Error occurred in myelin which is close-sourced, we’ve gotten stuck here for days and had no clue where to start debugging, so ask for your help:)


**TensorRT Version tensorrt 8.3:
**GPU Type Orin:
**Nvidia Driver Version 515:
**CUDA Version 11.4:
**CUDNN Version 8.2:

Steps To Reproduce

trtexec --onnx=swin_tiny_patch4_window7_224_opt.onnx --workspace=4096 --int8 --verbose --saveEngine=swin_tiny_patch4_window7_224_opt.trt

Request you to share the ONNX model and the script if not shared already so that we can assist you better.
Alongside you can try few things:

  1. validating your model with the below snippet

import sys
import onnx
filename = yourONNXmodel
model = onnx.load(filename)
2) Try running your model with trtexec command.

In case you are still facing issue, request you to share the trtexec “”–verbose"" log for further debugging

hello,onnx model downloads links is

trtexec run log is

We could successfully build TensorRT engine on latest the latest TensorRT version 8.4 GA. Please upgrade your TensorRT version.
