TensorRT conversion from tensorflow with custom op

[mssaeed]

Hi, I am trying to convert my tensorflow model with a custom op to a tensorRT model. I use the trtexec commandline tool to do so. I first convert the model from tensorflow to ONNX with tf2onnx which has my custom op that I included by passing the .so file (custom op library file) to tf2onnx. Later when I try to convert it to a TRT model I am unable to do so. I use the -plugin command line option with trt exec to which I pass the .so file.
This the error that I am currently running into. It is unable to even read the .so file. It says its not at the location mentioned, even though it is there.
Am I doing something wrong here or is there anyother way where I can convert my TF model with custom op in .so file to TRT?
Here is the command I am running and below is the error log.

trtexec --onnx=model_on.onnx --plugins=…/image_patch.so --saveEngine=engine.trt

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:

Quick Start Guide :: NVIDIA Deep Learning TensorRT Documentation

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.

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

Onnx model checker raises no flags and the model graph is also being produced right. I also verified the onnx model with netron.app.
The above documentation that you provided does not help either as it has no documentation on how to deal with cases of custom ops developed in C++.

I am using the trtexec to convert the model so there is no other script. Attached are the .so file that i used to convert TF to onnx and the converted onnx model.

model_on.onnx

Below is the --verbose log:

Hi,

Please locate the file libtensorflow_framework.so.2 and copy it to your folder, then export the path to the LD_LIBRARY_PATH.

export LD_LIBRARY_PATH=`pwd`:$LD_LIBRARY_PATH

Example path of libtensorflow_framework.so.2

/usr/local/lib/python3.10/dist-packages/tensorflow/libtensorflow_framework.so.2

Thank you.

[mssaeed]

Thank you. It is now able to read my library.
On the other hand it still does not recognize my OP. Is there a way around using a custom op written for tensorflow and using it for tensorRT, like onnx allows you to do it. Or is IPluginV2DynamicExt the only way to do so? Where I have to create new classes for both the plugin and plugin creator?
Attached is the log of my latest execution of trtexec.
Thank you.
