在PyTorch中,可以使用torch.nn.init.kaiming_normal_或torch.nn.init.kaiming_uniform_函数来应用Kaiming初始化。这些函数会根据指定的模式(fan_in或fan_out)和激活函数(如ReLU)来计算适当的权重尺度。fan_in模式是基于输入单元的数量来计算权重的方差,而fan_out模式是基于输出单元的数量来计算。 Kaiming初始化的优点...
Initialization of a large model for training is not always possible with the limited GPU memory. To resolve this problem of insufficient GPU memory, you can initialize the model on CPU memory. However, for larger models with more than 20 or 40 billion pa

billion parameter model we use 8 GPUs per model parallel group and 64-way data parallelism, for a total of 512 GPUs. All communication is implemented in PyTorch by Python calls to NCCL. GPUs within each model parallel group perform all-reduces amongst all GPUs within the group. For data par...
