安装dlib，然后各种报错，
什么cmake没装啊，
什么boost没装啊，然后都试了一遍，没解决
最后找到一个最合适的方法。（不用下载杂七杂八的）
1.首先下载文件dlib-19.7.0-cp36-cp36m-win_amd64.whl，在如下的链接中
链接: https://pan.baidu.com/s/1pz_mrmRTxppyRT2cTwtVIw 提取码: uc1u
py3.7链接: https://pan.baidu.com/s/1MKqW7WH2XP-J8MOLeq3cDA 提取码: rfh8
2.将其放到任意的路径下，然后通过命令行进入到该目录下，然后运行代码：
pip install dlib-19.7.0-cp36-cp36m-win_amd64.whl
之后回车安装即可。
错误信息很多
错误1
D:\Users\install-DLIB>pip install dlib-19.7.0-cp36-cp36m-win_amd64.whl
ERROR: dlib-19.7.0-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.
解决方法
版本不匹配查看python的版本是否匹配
我的py是3.7下载的是3.6
重新下载
