我正在尝试将 mpi4py 与 python3.5 一起使用，我已经在 Ubuntu 16.04 上安装了 openMPI，然后安装了 mpi4py 模块。
当我尝试导入 mpi4py 时出现以下错误:
Python 3.5.2 (default, Jul 5 2016, 12:43:10)
[GCC 5.4.0 20160609] on linux

It looks like opal_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
opal_shmem_base_select failed
--> Returned value -1 instead of OPAL_SUCCESS

[ubuntu:31733] Local abort before MPI_INIT completed successfully; not able to aggregate error messages, and not able to guarantee that all other processes were killed
我该如何解决这个问题？
最佳答案
我通过执行以下操作解决了这个问题:
删除现有安装:
sudo apt-get remove openmpi-bin
sudo apt-get remove python3-mpi4py
重新安装
sudo apt-get install libopenmpi-dev
sudo pip3 install mpi4py
sudo apt install openmpi-bin
