GroupNormalizationPlugin not found

[hrishi121]

Description

I have a simple test model that has two conv layers and a group norm in pytorch, and I want to serialize it to TensorRT. I converted the pytorch model to ONNX opset20. The groupnorm layer is broken down into instancenorm+few other operations in the ONNX graph. I have been following the onnx_packnet example, where it suggests to replace the instancenorm nodes and replace it with "GroupNormalizationPlugin" node (as shown in the sample post_processing.py script)

I followed the build instructions for "Native build on Jetson (aarch64)" and was able to build TensorRT OSS repo on Jetson AGX Orin.

However, when I try to parse the ONNX model using trtexec, I keep getting that "GroupNormalizationPlugin" not found

[01/04/2025-01:25:44] [E] Failed to parse onnx file

These are the commands that I am running to parse the ONNX model using trtexec:

export LD_LIBRARY_PATH=/usr/local/cuda/lib64:/home/nvidia/TensorRT/build/out:/home/nvidia/TensorRT-10.7.0.23/lib
/home/nvidia/TensorRT-10.7.0.23/bin/trtexec --onnx=/home/nvidia/replaced_plugin.onnx --verbose

where,

/home/nvidia/TensorRT/ path refers to TensorRT OSS path and the out directory contains the compiled .so files
/home/nvidia/TensorRT-10.7.0.23/lib is the path to the TensorRT-10.7 GA release downloaded from nvidia website

Environment

TensorRT Version: 10.7.0.23

NVIDIA GPU: Jetson AGX Orin

NVIDIA Driver Version:

CUDA Version: 12.6

CUDNN Version:

Operating System: Jetson native build

Python Version (if applicable):

Tensorflow Version (if applicable):

PyTorch Version (if applicable): 2.5.1

Baremetal or Container (if so, version):

Relevant Files

Model link: replaced_plugin.onnx

Steps To Reproduce

Commands or scripts:

Have you tried the latest release?: Yes

Can this model run on other frameworks? For example run ONNX model with ONNXRuntime (polygraphy run <model.onnx> --onnxrt):

If you has build the nvinfer_plugin.so, you can add some print infos in your code like https://github.com/NVIDIA/TensorRT/blob/release/10.7/plugin/groupNormalizationPlugin/groupNormalizationPlugin.cpp#L350

https://github.com/NVIDIA/TensorRT/blob/release/10.7/plugin/groupNormalizationPlugin/groupNormalizationPlugin.cpp#L394

https://github.com/NVIDIA/TensorRT/blob/release/10.7/plugin/groupNormalizationPlugin/groupNormalizationPlugin.cpp#L431

to check your plugin version is loaded right.
