Zugriffsverletzung Schreibort in opencv

Question

Ich bekomme Zugriffsverletzung Schreibort in Gesichtserkennung in opencv, wenn der Code zu dieser Zeile: Modell-> Zug (Bilder, Etiketten);

der Fehler: Unbehandelte Ausnahme bei 0x00007FF9B494321B (opencv_core331.dll) in WHomeCamera.exe: 0xC0000005: Zugriffsverletzung Schreibort 0x0000000100000014. aufgetreten

    try 
    {

     images.push_back(imread("D:\imagesForProject\3.jpg", CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image; 
     labels.push_back(0); // insert his label; 


    } 

    catch(Exception& e) 
    { 
     cerr << "can't open the images" << e.msg << endl; // if we couldn't  open the files cerr it's basic cout for errors;

    Ptr<FaceRecognizer> model = FisherFaceRecognizer::create(); 
    model->train(images, labels); 
    return(0);

OpenCV 3.3 gebaut von mir G++ 5.4 auf Ubuntu 16.04 verwenden.

Dieser Code funktioniert für mich. Do not ask me why, Sie should finden Sie den Unterschied .

    Ptr<FaceRecognizer> model = FisherFaceRecognizer::create(); 
    model->train(images, labels); 
    model->save("xxx.xml"); 
    return(0);
