Models face-detection-0205 and face-detection-0206 showing errors

Hey guys! I’m trying to run the face-detection-0205 and the face-detection-0206 but i wasn’t able to get the proper output result, instead of that i got:

terminate called after throwing an instance of 'InferenceEngine::details::InferenceEngineException'
  what():  [PARAMETER_MISMATCH] Failed to set output Blob. Dimensions mismatch.
Aborted (core dumped)

I’m using OpenCV 4.5.1 with OpenVINO 2021.2 with the following code:

cv::dnn::Net detect = cv::dnn::readNet(
      path + "/face-detection-0206/deploy.xml", path + "/face-detection-0206/model.bin", "DLDT");
  detect.setPreferableBackend(2);

  cv::VideoCapture cap(argv[2]);  // cap(0);

  cv::Mat frame;
  int total_frames = 0;
  float total_time = 0;
  while (true) {
    cap >> frame;

    if (frame.empty()) {
      std::cerr << "End of stream" << std::endl;
      exit(0);
    }
    detect.setInput(cv::dnn::blobFromImage(frame, 1.0, cv::Size(640, 640),
                                           cv::Scalar(), false, false, CV_32F),
                    "image");

    cv::Mat a;
    detect.forward("labels");

Also i get the same problem with cv::dnn::DetectionModel

@campos537 those two a new models, introduced in OpenVINO 2021.2. It might be OpenCV DNN was not updated yet to support them.

Thanks for the explanation @vladimir-dudnik! I tested the two output layers “labels” and “boxes” but for some reason didn’t worked with C++ OpenCV dnn don’t know why.
