python+opencv环境搭建

在cmd中输入命令：
pip install --upgrade setuptools
pip install numpy Matplotlib
pip install opencv-python

即可
网络原因报错的话需要重新设置源网址：

import os

ini="""[global]
index-url = https://pypi.doubanio.com/simple/
[install]
trusted-host=pypi.doubanio.com
"""
pippath=os.environ["USERPROFILE"]+"\\pip\\"

if not os.path.exists(pippath):
    os.mkdir(pippath)

with open(pippath+"pip.ini","w+") as f:
    f.write(ini)
