faiss vector engine install.md

基本是按照文档顺序，此处对INSTALL.md做补充

安装BLAS/LAPACK

Ubuntu

不必按照INSTALL.md里面的编译安装方法，只要安装源里的包即可

$ sudo apt install libopenblas-dev
$ sudo apt install liblapack
$ sudo apt install swig

CentOS7

$ sudo yum install openblas-devel
$ sudo yum install lapack-devel
$ sudo yum install swig

制作test_blas

$ make tests/test_blas

如果make不过，应该是ld的问题，实在make不过直接把g++命令贴出来手动搞

开始编译 faiss

$ cp example_makefiles/makefile.inc.Linux makefile.inc
$ make

开始编译py wrapper

请安装包python-numpy，如果你像我一样想使用virtualenv，那么请将makefile.inc中PYTHONCFLAGS修改为如下内容 PYTHONCFLAGS=-I/usr/include/python2.7/ -I${VIRTUALENV_PATH}/lib/python2.7/site-packages/numpy/core/include/

$ make py
