使用python2.7安装opencv-python时报错，在https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple/opencv-python/找到2.7对应版本
其中下载opencv_python-3.1.0.0-cp27-cp27m-manylinux1_x86_64.whl安装时报错：
opencv_python-3.1.0.0-cp27-cp27m-manylinux1_x86_64.whl is not a supported wheel on this platform.
执行命令：
import pip
print(pip.pep425tags.get_supported())
显示支持的版本如下
[('cp27', 'cp27mu', 'manylinux1_x86_64'), ('cp27', 'cp27mu', 'linux_x86_64'), ('cp27', 'none', 'manylinux1_x86_64'), ('cp27', 'none', 'linux_x86_64'), ('py2', 'none', 'manylinux1_x86_64'), ('py2', 'none', 'linux_x86_64'), ('cp27', 'none', 'any'), ('cp2', 'none', 'any'), ('py27', 'none', 'any'), ('py2', 'none', 'any'), ('py26', 'none', 'any'), ('py25', 'none', 'any'), ('py24', 'none', 'any'), ('py23', 'none', 'any'), ('py22', 'none', 'any'), ('py21', 'none', 'any'), ('py20', 'none', 'any')]
根据提示将opencv的whl文件更换为
opencv_python-3.1.0.0-cp27-cp27mu-manylinux1_x86_64.whl
安装成功！
