MegatronLM的第一篇论文【Megatron-LM: Training Multi-Billion Parameter Language Models Using Model Parallelism】是2020年出的,针对billion级别的模型进行训练,例如具有38亿参数的类GPT-2的transformer模型和具有39亿参数的BERT模型。 分布式训练的模型并行有两种方式,一种是层间并行(inter-layer),也就是Pipeline流水...

tensor model parallel group is already initialized "tensor model parallel group is already initialized" 这句话是关于TensorFlow的模型并行化(model parallelism)的一种警告信息。在模型并行化中,模型的不同部分可以在不同的设备(例如,不同的GPU)上运行。为了实现这一点,TensorFlow需要初始化一个"model parallel ...

模型并行训练( Model Parallel Training) 还可以对模型进行切分,让模型的不同部分执行在不同的设备上,这样可以一个迭代的样本可以在不同的设备上同时执行。如上图所示的LSTM模型 最近项目需要,客户想上tensorflow,想把项目做的高大上一点,向我咨询tensorflow的相关问题和部署方案,我要假装自己很懂TF,之前一直在跟进te...
