opencv读取图片失败，“error C2022: “438”: 对字符来说太大”

Question

```int main()
{

Mat src = imread("E:\666.jpg", CV_LOAD_IMAGE_ANYCOLOR);
if (src.empty())
{
cout << "图像加载失败！" << endl;
return -1;
}
namedWindow("MyWindow", CV_WINDOW_AUTOSIZE);
imshow("MyWindow", src);

本人opencv入门选手，代码很简单如上所示，用的win7+vs2015+opencv3.1.0,生成项目时imread那一行就会报错
error C2022: “438”: 对字符来说太大
求问各位大神这是什么原因阿，该怎么改呢？

Answer 1

 Mat src = imread("E:\666.jpg", CV_LOAD_IMAGE_ANYCOLOR);
->
Mat src = imread("E:\\666.jpg", CV_LOAD_IMAGE_ANYCOLOR);
