[源码解析] PyTorch分布式(5) --- DistributedDataParallel 总述&如何使用 0x01 回顾 1.1 基本概念 关于分布式通信,PyTorch 提供的几个概念是:进程组,后端,初始化,Store。 进程组:DDP是真正的分布式训练,可以使用多台机器来组成一次并行运算的任务。为了能够让 DDP 的各个worker之间通信,PyTorch 设置了进程组这个概念。
PyTorch支持多种协议,包括tcp://、file://和env://等。 tcp://IP:PORT:通过TCP/IP地址和端口号来初始化分布式环境。所有参与训练的进程都需要能够访问这个IP地址和端口。 file:///tmp/sharedfile:通过文件系统上的一个共享文件来初始化。所有参与训练的进程都需要能够访问这个文件。 env://:通过环境变量来...
