那么很自然的,便是将神经网络的权重层初始化为一个单位矩阵,这种初始化方法被称为恒等初始化(Identity Initialization)。在理论上恒等初始化具有相当好的性质,这种性质被称为动力等距(Dynamical Isometry),最早由 Saxe 等人在2014年提出,它描述了当输入输出的雅可...

DeepSpeed is compatible with PyTorch (opens in new tab). One piece of that library, called ZeRO, is a new parallelized optimizer that greatly reduces the resources needed for model and data parallelism while massively increasing the number of parameters that ...
ZeRO Infinity 基于 PyTorch 代码实现,并且不用重构任何模型代码 Automating Data Movement ZeRO-Infinity 需要协调模型参数、梯度和优化器状态数据移动,必须确保这些数据在被使用前移动到 GPU 内存中,并在使用之后重新分配位置 PyTorch 模型以层级模块的形式表示,代表着神经网络的各个层次。例如,Transformer 架构中包含了诸...
The framework is implemented using PyTorch and runs on an NVIDIA 4090 GPU equipped with 24 GB of memory. During training, we employ a batch size of 8. The initialization of the weights for each layer follows a standard Gaussian distribution with a mean of zero and a standard deviation of ...
3. DeepNVMe module, created by the DeepSpeed team, allows for asynchronously reading and writing tensors to NVMe storage at near-peak NVMe bandwidth in PyTorch. Learn how DeepNVMe supports high-performance NVMe reads and writes for ZeRO-Infinity In addition to achieving ...
