Build engine from onnx failed

Description

I use a docker container build from tensorflow/tensorflow:2.5.0-gpu, and download tensorrt by myself in this container. It failed when I try to build an engine from my onnx model, and I can’t find any helpful information from the error message. I upload my onnx file here, and anyone may help me build the engine(any environment is OK…)? Or just tell me why I can’t build engine. Thanks!

update

solve the problem using the tensorrt ngc(21.11-py3) temporarily, and I have removed the onnx model.

Hi,
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

check_model.py

import sys
import onnx
filename = yourONNXmodel
model = onnx.load(filename)
onnx.checker.check_model(model).
2) Try running your model with trtexec command.
https://github.com/NVIDIA/TensorRT/tree/master/samples/opensource/trtexec
In case you are still facing issue, request you to share the trtexec “”–verbose"" log for further debugging
Thanks!
