Linux下安装dlib那些幺蛾子

1、安装步骤参见：

https://gist.github.com/ageitgey/629d75c1baac34dfa5ca2a1928a7aeaf

 

用git clone dlib库：git clone https://github.com/davisking/dlib.git

 

进入dlib目录：cd dlib

 

执行：mkdir build，创建build目录

 

进入dlib/build目录： cd build

 

执行：cmake ..

 

执行：cmake --build .

 

编译完成后，回到dlib目录：

cd ..

执行：python3 setup.py install  （这里注意，如果是python2.x，请用python setup.py install）

 

 

2、用cmake进行编译安装，如过没有cmake，记得安装，最好是3.x以上，如果cmake版本是2.x的记得卸载后升级到3.x，因为isuse上说，最好是用3.x以上的cmake

 

3、当你执行到 python3 setup.py install  这一步时（我的环境是python2.7 ，用的是python  setup.py install），可能会出现一下错误：

译中断。

这时，安装yum install python-devel，可以解决上述问题。

 

至此，终于安装完成。
