Fail to load onnx model quantized by Intel neural-compressor #22509
Description
System information (version)
- OpenCV => 4.6.0
- Operating System / Platform => Windows 64 Bit
- Compiler => Visual Studio 2019
Detailed description
When I load onnx model which was quantified by script from opencv_zoo with the Intel neural-compressor>1.10.1, it will cause an error. (This model can be run correctly by onnx_runtime)
[ERROR:0@80.629] global D:\a\opencv-python\opencv-python\opencv\modules\dnn\src\onnx\onnx_importer.cpp (1021) cv::dnn::dnn4_v20220524::ONNXImporter::handleNode DNN/ONNX: ERROR during processing node with 11 inputs and 1 outputs: [QLinearConcat]:(onnx_node!StatefulPartitionedCall/model/regressors/concat_quant) from domain='com.microsoft'

When I use Intel neural-compressor==1.10.1, the mdoel can be loaded. Several models have this problem as well.
Steps to reproduce
Demo model file: palm_detection_mediapipe_2022may-int8-quantized.onnx
Python code:
import cv2
net = cv2.dnn.readNetFromONNX("path/to/model")
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues,
forum.opencv.org, Stack Overflow, etc and have not found any solution - I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files: videos, images, onnx, etc
