在docker里安装了xlearn后，跑demo，直接报错。请问这是什么情况呢？

@CoolIceFire 请问你运行的是哪一个demo。这个原因一般都是运行过程中出现了野指针之类的错误，但是按理说 demo 应该不会出错的。你能提供更多的错误信息吗？

我把代码clone到container里后，运行每一个demo，都是会报错 "terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_M_construct null not valid Aborted (core dumped)"

又重现了一下，用的docker镜像是registry.cn-hangzhou.aliyuncs.com/xdl/xdl:ubuntu-cpu-tf1.12

@aksnzhy 最近测 xlearn 发现了这个问题. 根据 #115 这个 issue 的解决方案我简单对比了一下. 没有设置 USER 环境变量的都会出现这个 bug. 包括容器内部和 crontab 任务. 我没看过源码, 但推测是不是有地方会去获取 USER 的环境变量然后赋值给了一个 *string, 没有则 *string 为 null 从而产生了这个 bug.
