C++ OpenCV 问题

// 代码来自于互联网
#include <iostream>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

int main() {
    // std::cout << "Hello, World!" << std::endl;
    // Mat srcImage = imread("C_test.jpg");
    Mat srcImage = imread("/Users/*/Code/CLionProjects/OpenCV_unit/C_test.jpg"); // /Users/*/Code/CLionProjects/OpenCV_unit/C_test.jpg
    /**
    if (srcImage.empty()){
        std::cout << "Can not load image" <<std::endl;
        return 0;
    }**/
    imshow("[img]", srcImage);
    waitKey(0);
    return 0;
}

使用时 Mat srcImage = imread("C_test.jpg"); 出现问题 ：

OpenCV Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /tmp/opencv-20180113-47978-vhoedt/opencv-3.4.0/modules/highgui/src/window.cpp, line 331
