torchrun是PyTorch库中用于启动分布式训练的命令行工具,特别是在使用PyTorch Distributed Package时。它简化了分布式训练的启动过程,自动处理了如初始化进程群、设置环境变量等复杂步骤,使得在多GPU或者多节点环境下的分布式训练变得更加便捷 3.2 torchrun主要用途 多GPU训练:在单机多GPU环境下执行分布式训练。 多节点训练:...
torchrun分布式推理能高效利用多设备资源加速推理过程。 它是基于PyTorch的分布式推理解决方案。torchrun通过简单命令即可启动分布式推理任务。可在多台服务器或同一服务器多GPU上运行推理。支持多种网络拓扑结构进行分布式计算。能显著减少大规模模型推理的响应时间。分布式推理可实现负载均衡提升效率。torchrun为分布式推理提供...

torchrun --nproc_per_node=4 --nnodes=3 --node_rank=0 --master_addr=192.168.0.101 --master_port=29500 test_mpi.py 1. 常见参数 1.指定每个节点(机器)上的进程数,这里是4个。意味着每个机器将启动4个进程来参与分布式训练。 --nproc_per_node=4 1. 2.指定总共的节点数,这里是3个。意味着总共...
Pytorch在1.9.0引入了torchrun,用其替代1.9.0以前版本的torch.distributed.launch。torchrun在torch.distributed.launch 功能的基础上主要新增了两个功能: Failover: 当worker训练失败时,会自动重新启动所有worker继续进行训练; Elastic: 可以动态增加或或删除node节点; ...
在1.9 版本之后默认加入了TorchElastic来支持分布式训练的弹性容错,并且提供了torchrun来支持启动弹性容错进程。torchrun 相比torch.distributed.launch无需配置 RANK, WORLD_SIZE, MASTER_ADDR 和 MASTER_PORT 等环境变量。torchrun 通过动态 Rendezvous 来帮助训练子进程进行集合通信组网。本文将介绍 PyTorch 弹性容错组网...
