opencv 报错 error: (-215) ksize.width > 0 && ksize.width % 2 == 1 && ksize.height > 0 && ksize.height % 2 == 1 in function cv::createGaussianKernels

import cv2

img = cv2.imread('MAYI1.jpg', 0)#读取初始图片

ret, yuzhi = cv2.threshold(img, 116, 255, cv2.THRESH_BINARY)
mohu = cv2.GaussianBlur(yuzhi, (8, 8), 0)#阈值和模糊处理

试图运行此段代码，报错

修改高斯模糊内核大小之后

import cv2

img = cv2.imread('MAYI1.jpg', 0)#读取初始图片

ret, yuzhi = cv2.threshold(img, 116, 255, cv2.THRESH_BINARY)
mohu = cv2.GaussianBlur(yuzhi, (9, 9), 0)#阈值和模糊处理

原来内核大小只支持奇数

解决！
