Ubuntu mpi4py无法编译

标签： python linux ubuntu openmpi mpi4py

我有Ubuntu Desktop LTS 16.04.1，我做了以下操作。我去了https://www.open-mpi.org/software/ompi/v2.0/，下载了openmpi-2.0.1.tar.gz并使用以下命令安装它：

tar -xvf openmpi-2.0.1.tar.gz
cd openmpi-2.0.1
./configure --prefix="/home/$USER/.openmpi"
make
sudo make install
export PATH="$PATH:/home/$USER/.openmpi/bin"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/.openmpi/lib/"
echo export PATH="$PATH:/home/$USER/.openmpi/bin" >> /home/$USER/.bashrc
echo export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/.openmpi/lib/" >> /home/$USER/.bashrc

之后，我使用：

安装了mpi4py 
sudo apt-get update
sudo apt-get install python-mpi4py

之后，我创建了一个名为something.py的Python文件（我的Python版本为Python 2.7.12），其中包含以下行

from mpi4py import MPI
comm = MPI.COMM_WORLD
rank = comm.Get_rank()
print "hello world from process ", rank

当我尝试使用mpiexec -n 5 python something.py运行它时，我得到以下内容：

大多数解决方案都说要直接从源代码安装openmpi，我这样做了，但这似乎并没有解决我的问题。任何人都有类似的问题吗？

答案 0 :(得分：1)

我刚刚解决了这个问题：我卸载了mpi4py，我安装了python-pip，并通过pip安装了sudo mpi4py。命令清单：

sudo apt-get remove python-mpi4py
sudo apt-get update && sudo apt-get -y upgrade
sudo apt-get install python-pip
sudo pip install mpi4py

注意：在sudo apt-get update＆amp;＆amp; amp;之后你将不得不等待一段时间。 sudo apt-get -y升级。这个问题现在可以关闭了，谢谢。
