问题描述：

【问题描述】

使用singularity方式创造ubuntu镜像安装MindSpore ，出现 cudaSetDevice failed, ret[999], unknown error 问题

原生操作系统:  CentOS Linux release 7.4.1708 (Core)

singularity版本： 3.5.2

镜像操作系统： ubuntu 18.04.5 LTS (Bionic Beaver)  

镜像源： docker://nvidia/cuda:10.1-cudnn7-devel-ubuntu18.04

在镜像操作系统安装MindSpore1.1.1 按照安装步骤安装成功，使用样例程序验证报错：
