因为我编译安装用的Python3.5，所以

cd /usr/lib/x86_64-linux-gnu/
sudo unlink libboost_python.so
sudo unlink libboost_python.a
sudo ln -s usr/lib/x86_64-linux-gnu/libboost_python-py35.so usr/lib/x86_64-linux-gnu/libboost_python.so
sudo ln -s usr/lib/x86_64-linux-gnu/libboost_python-py35.a  usr/lib/x86_64-linux-gnu/libboost_python.a
