import torch

提示如下错误，

OSError: libmpi_cxx.so.20: cannot open shared object file: No such file or directory

然后首先

sudo apt-get update

然后执行

apt-get install libopenmpi-dev

再次import torch发现错误消失，但是出现如下错误

ImportError: libopenblas.so.0: cannot open shared object file: No such file or directory

执行如下命令
