Python 使用openmpi时无法修改队列对的属性

今天我在调用mpirun时遇到了一个mpi异常，以前从未见过。例外情况是：

[@nmyjs_104_22 ~]$ mpirun -np 1 echo "hello"
--------------------------------------------------------------------------
Failed to modify the attributes of a queue pair (QP):

Hostname: nmyjs_104_22
Mask for QP attributes to be modified: 113
Error:    Invalid argument
--------------------------------------------------------------------------
--------------------------------------------------------------------------
Open MPI has detected that there are UD-capable Verbs devices on your
system, but none of them were able to be setup properly.  This may
indicate a problem on this system.

You job will continue, but Open MPI will ignore the "ud" oob component
in this run.

输出似乎意味着openmpi无论如何都会运行。但在这种情况下，我的代码即使只是运行一个简单的命令也会失败

例如，

mpirun-np 1 echo“hello world”

，例外情况是：

[@nmyjs_104_22 ~]$ mpirun -np 1 echo "hello"

我在谷歌上搜索了一下，但没有找到运气。我今天做的是将openmpi从2.0.2更新到2.1.0，它位于。我还将openmpi恢复为2.0.2，但仍然存在此错误。希望有人能帮忙

谢谢你

你可能会更幸运地在openmpi邮件列表中询问。另外请注意，在异常的末尾“要求”您检查是否省略了-np。谢谢您的回复。是的，我也在

openmpi

邮件列表中询问过。希望他们能帮我。而且

-np

应该不是问题，因为它只是简单测试中不必要的参数。您的

mpirun

命令是什么？！您似乎忘记包含一些必需的参数。谢谢您的帮助。但这应该不是问题。即使我使用如下命令：

mpirun-np1 python-c“print（'hello world'）”

，仍然存在异常
