Polygraphy: how to compare the precision layer by layer with TensorRT if I have a custom operator in my onnx (and a corresponding plugin in TensorRT)?

Description

I used to check my engine(tensorRT) layer by layer with onnx using polygraphy tool. But I have a custom operator writen by myself in my onnx, and a corresponding plugin in my tensorRT now and how can I compare them layer by layer using polygraphy?

I write the .sh script like this:

 polygraphy run my_model_with_custom_operator.onnx  \
                --onnxrt --trt  \
                --trt-outputs mark all  \
                --onnx-outputs mark all  \
                --atol 1e-3  --rtol 1e-3  \
                --fail-fast  \
                --val-range [0,1]  \
                --verbose 

And I get error as below:
onnxruntime.capi.onnxruntime_pybind11_state.Fail: [ONNXRuntimeError] : 1 : FAIL : Fatal error: customPlugin(-1) is not a registered function/op

Thank you very much.

Environment

TensorRT Version:
8.4.0.6

NVIDIA Driver Version:
535.183.01

CUDA Version:
11.3

CUDNN Version:
8.3.2.44

Operating System:

Python Version (if applicable):
3.9.7

PyTorch Version (if applicable):
1.13.0

Start with the reported Polygraphy shell command and the ONNX Runtime error that customPlugin is not registered. Investigate how the custom operator and corresponding TensorRT plugin are made available to the two backends; done means the model runs successfully and layer-by-layer comparison completes.
