1、下载到本地，使用python3.7 setup.py install编译
2、加大swap区
3、一部分一部分的编译，在遇到
g++: scipy/sparse/sparsetools/csr.cxx
g++: scipy/sparse/sparsetools/csc.cxx
g++: scipy/sparse/sparsetools/bsr.cxx
bsr，csr，csc并行编译时共计6个进程(每一个启动两个进程)，
（1）先kill掉四个（每个会有两个进程），编译成功一个。
（2）然后重新编译，会有4个进程，kill掉相关的两个，等待其中一个编译完成。
（3）然后再次重新编译，只有2个进程了，顺利编译完成。
4、一定要重启！一定要重启！一定要重启！否则直接运行python3.7 ,然后import scipy会报错。
5、监控内存的脚本
while true; do free -m; sleep 3; done
