而后构建dataset和collector后(参见pytorch训练),则可以对模型进行训练 model_engine, optimizer, train_loader, lr_schdlr = deepspeed.initialize(model=model_pipe, config=ds_config, model_parameters=model_pipe.parameters(), training_data=train_dataset) for i in range(args.num_train_epochs * num_update...
模型变得越来越大,单卡都无法支持一个模型训练的时候,就会使用模型并行的方法,模型并行又分为流水线并行(Pipeline Parallelism)和张量并行(Tensor Parallelism),其中流水线并行指的是将模型的每一层拆开分布到不同GPU。当模型大到单层模型都无...

Pipeline communications are implemented using broadcast collectives between groups of size 2. Starting with PyTorch 1.8+, the bundled NCCL version also supports send/recv, and so I am preparing to release a new backend that uses send/recv when available. Other collectives include AllReduce for grad...
相比之下,经典数据并行方法的实现(如PyTorch分布式数据并行)在1.4亿个参数的模型上会耗尽内存,而ZeRO-1则支持最多6亿个参数。 此外,在没有模型并行的情况下,这些模型可以在带宽较低的集群上进行训练,同时仍然比使用模型并行获得显着更高的吞吐量。例如,使用40 Gbps Infiniband互连连接的四个节点集群(每个节点具有四...

这个错误是由于PyTorch版本变化产生的,搜索了一下,发现只需要把from torch._six import inf这行代码改成from torch import inf就可以了。继续执行,报错为:AssertionError: make sure to set PATH for wikipedia data_utils/corpora.py。这是因为在scripts/pretrain_gpt2.sh里面指定了训练的数据集为 wikipedia ,所以...
