1、安装第三方库

sudo apt-get install cmake==3.18.2
#（已经安装cmake，升级一下：sudo pip install --upgrade cmake==3.18.2）

sudo pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/  pytest

2、安装pybind11

1）源码下载

github：https://github.com/pybind/pybind11
克隆下来

git clone https://github.com/pybind/pybind11.git

2）编译安装

cd  pybind11
mkdir build
cd build
cmake ..
make check -j 4 
sudo make install  #(如果使用python2需要禁用/usr/bin/下的python3)

可以看到安装完成之后include的目录是在：/usr/local/include/，而不是在/usr/include，如果发现导入不存在，则用全路径导入

#include <string>
#include <sstream>

#include </usr/local/include/pybind11/pybind11.h>
#include </usr/local/include/pybind11/eigen.h>
#include </usr/local/include/pybind11/stl.h>

#include "teaser/registration.h"
#include "teaser/certification.h"

namespace py = pybind11;
