Steps to reproduce

1. download model: https://tfhub.dev/google/movenet/singlepose/thunder/4?tf-hub-format=compressed
2. convert model : python -m tf2onnx.convert --saved-model ./movenet_singlepose_thunder_4 --output model_pb.onnx
3. load model the follow code:

# python
import cv2

print(cv2.__version__)
net = cv2.dnn.readNetFromONNX("./model_pb.onnx") 
image = cv2.imread("person.jpeg") 
blob = cv2.dnn.blobFromImage(image) 
net.setInput(blob)  
out = net.forward() 

#include <opencv2/opencv.hpp>
#include <iostream>
#include <stdexcept>

using namespace cv;
using namespace cv::dnn;
using namespace std;

int main() try {
    system("color F0");

    cout << "version:" << cv::getVersionString() << endl;

    string model = "../model/model_pb.onnx";
    Net net = dnn::readNet(model);
    if(net.empty()){
        cout << "确认是否输入了空的模型文件" << endl;
        return -1;
    }
    vector<string> layerNames = net.getLayerNames();
    for (size_t i = 0; i < layerNames.size(); i++)
    {
        int ID = net.getLayerId(layerNames[i]);
        Ptr<Layer> layer = net.getLayer(ID);
        cout << "网络层数" << ID << " 网络层名称 " << layerNames[i] << " 类型 " << layer->type.c_str() << endl;
    }
    
    cout << "ok" << endl;
}catch(std::exception const &ex){
    cerr<<ex.what()<<endl;
}

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
