某些节点上的Python mpi4py脚本分段错误

Question

一个简单的python mpi脚本在集群的特定节点上崩溃，并出现分段错误。在

脚本的主体是：

import mpi4py 
mpi4py.rc.threads = False 
from mpi4py import MPI 
comm = MPI.COMM_WORLD
name=MPI.Get_processor_name()

print("hello world")
print(("name:",name,"my rank is",comm.rank)) 

我尝试过在单个节点上运行脚本之前加载批处理文件中的所有模块，但这不起作用。sbatch文件如下所示：

^{pr2}$

输出的前几行如下所示节点的实际名称被NODENAME替换，INSTITUTE是我工作的地方的占位符：

[NODENAME:24753] *** Process received signal ***
[NODENAME:24753] Signal: Segmentation fault (11)

我猜这些节点上没有加载模块。在
