在opencv中访问违规写入位置

Question

当代码到达此行时，我在opencv中的面部识别器中获得访问冲突写入位置：model-> train（images，labels）;

错误：WHOMECamera.exe中0x00007FF9B494321B（opencv_core331.dll）的未处理异常：0xC0000005：访问冲突写入位置0x0000000100000014。发生了

using namespace std;

int main(void)

    vector <Mat> images; // vector of matrix for the images of the faces;
    vector <int> labels; // vector of int's for the labes (each person get      label ex: moshe - 0);

    try
    {
        images.push_back(imread("D:\imagesForProject\1.jpg",    CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image;
        labels.push_back(0); // insert his label;

        images.push_back(imread("D:\imagesForProject\2.jpg", CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image;
        labels.push_back(0); // insert his label;

        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由我自己在G++ 5.4上使用Ubuntu 16.04建造。

这段代码适合我。 Do not ask me why，你should找到差异by yourself。
