Hello_World不在集群上使用mpi4py：II

Question

再次尝试在本地集群上学习mpi4py。我因此写了一个hello_world程序，它不会运行！我附加了.py代码和错误。有人能指出我做错了什么吗？提前致谢。

的Hello World：

from mpi4py import MPI 
comm=MPI.COMM_WORLD 
print("Hello, World! My rank is: " + str(comm.rank)) 

错误消息：

Traceback (most recent call last): 
File "./MPI_Hello_World.py", line 1, in <module> 
from mpi4py import MPI 

ImportError: libmpich.so.3: cannot open shared object file: No such file or directory

See here for the part-I of the question.

我一点儿也不熟悉MPI4PY，但它看起来像它需要一个单独的MPI安装为一体反对提供自己的。你尝试安装一个（MPICH，开放MPI等），在大多数Linux系统，这是做一个快速

apt-get install mpich 

或任何你的气息的包管理器一样简单。如果你想要最新最好的，你可以从项目的网站获取相对简单的指令：

MPICH：www.mpich.org

开放MPI：wwww.open-mpi.org
