if __name__ == "__main__":
    im = cv2.imread(sys.argv[1])
    im_gray = cv2.cvtColor(im, cv2.COLOR_BGR2GRAY) /`enter code here` 255.

    f = numpy.load(sys.argv[2])

        pt2 = tuple(reversed(map(int, pt2)))

    cv2.imwrite(sys.argv[3], im)

error  im = cv2.imread(sys.argv[1])
IndexError: list index out of range)

在这里输入代码

Answer 1

键入cmd上的代码，并确保您位于包含weights.npz文件的正确文件夹下（这可能是CPUweights.npz在执行train.py后检查此文件名）。并设置检测到的图片名称为in.jpg也在同一文件夹下

python detect.py in.jpg CPUweights.npz out.jpg

Answer 2

您可以查看更新的自述文件以找到解决方案。

./ detect.py in.jpg weights.npz out.jpg
