Microsoft MPI和mpi4py 3.0.0，python 3.7.1当前是否可能?

问题描述

在尝试了所有可以想象和无法想象的一切之后，我感到非常沮丧，似乎他们的SDK( https://www.microsoft.com/zh-cn/download/details.aspx?id=57467 )缺少了一些内容:

I am very frustrated after a whole week of trying everything imaginable and unimaginable, it seems that their SDK ( https://www.microsoft.com/en-us/download/details.aspx?id=57467 ) is missing something:

如果真的不可能使其正常工作，请告诉我应该使用哪种MPI分发而不是Microfost MPI，因为 https://www.mpich.org/downloads/没有为Windows提供任何替代方法.

If it's really impossible to make it work, then tell me which distribution of MPI should I use instead of Microfost MPI, since https://www.mpich.org/downloads/ does not provide any alternatives for Windows.

P.S .: mpi4py 2.0.0与python 3.7不兼容(至少Anaconda告诉我)，所以我宁愿选择另一种MPICH发行版(如果有)而不是降级我的python.

P.S.: mpi4py 2.0.0 is incompatible with python 3.7 (at least Anaconda tells me so), so I 'll rather choose another distribution of MPICH (if there is one) than downgrade my python.

推荐答案

我已将其与3.7.0一起使用...

I've got it working with 3.7.0...

我从 https://www.microsoft.com下载了MSMPI .com/en-us/download/details.aspx?id = 57467 我运行了两个文件，然后将其添加到PATH中(C:\ Program Files(x86)\ Microsoft SDKs \ MPI)

I downloaded MSMPI from https://www.microsoft.com/en-us/download/details.aspx?id=57467I ran both files, then added it to the PATH(C:\Program Files (x86)\Microsoft SDKs\MPI)

然后我只用了python -m pip install mpi4py

要运行MPI程序，我们然后mpiexec -n [number of cores] python .\filename

To run a MPI program, I then us mpiexec -n [number of cores] python .\filename

我正在Windows 10中的AMD A-10 9600P上运行.

我确实安装了Visual Studio，因此它可能会挂接到一些您没有的库中.

I do have Visual Studio installed, so it's possible that it's hooking into some libs you don't have...
