Question

再次尝试在本地群集上学习mpi4py。因此我写了一个hello_world程序，它肯定不会运行！我附加了.py代码和错误。有人能指出我做错了什么吗？提前谢谢。

你好世界：

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

from mpi4py import MPI

See here for the part-I of the question.

我对MPI4PY并不熟悉，但看起来它需要单独的MPI安装，而不是提供自己的MPI。您是否尝试过安装一个（MPICH，Open MPI等）在大多数Linux系统上，这就像快速做一样简单

apt-get install mpich

或者你的风味套餐经理是什么。如果您想要最新和最好的，您可以从项目的网站获得相对简单的说明：

MPICH：www.mpich.org

打开MPI：wwww.open-mpi.org

Hello_World在Cluster：II上没有使用mpi4py
