单机单卡运行失败

[wangshankun]

单机train的时候当指令ng=1，不论是train还是test都会遇到同样的error；

当 --ng=1的时候出现Error:“`........please make sure to call init_process_group”

For single device, maybe you don't need allreduce @wangshankun.

OK，But how to remove allreduce when only have one gpu card？

Just delete this line or note it when world_size <= 1 @wangshankun
