python dlib安装

参考文档
dlib安装
dlib安装

在安装dlib库时，会遇上很多问题，特别时用pip安装时，因为没有安装cmake和boost等工具就会出错。

yum install gcc gcc-c++
yum install cmake boost
yum install opencv opencv-python opencv-devel python-devel numpy
pip install dlib -i https://pypi.douban.com/simple/

Collecting dlib。。。。
 CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
解决办法

yum install cmake gcc-c++

另一个问题
另外一个地方可能会报错
fatal error: Python.h: No such file or directory
 #include 
                   
compilation terminated.

解决办法:

debain系

sudo apt install python3-dev

rehat系

yum install python3-devel
