解決方案
1. 安裝imageio模塊文章來源：http://www.zghlxwxcb.cn/news/detail-839432.html
# 安裝imageio模塊，執(zhí)行其一即可
pip install imageio -i https://pypi.tuna.tsinghua.edu.cn/simple some-package
conda install imageio
2. 代碼修改文章來源地址http://www.zghlxwxcb.cn/news/detail-839432.html
# 原代碼
import cv2
img = cv2.imread(path)
# 替換后代碼，代碼可正常運行
import imageio
img = imageio.imread(path)
