and can modestly improve performance. However, it changes certain behaviors. For example: 1. When the user tries to access a gradient and perform manual ops on it, a None attribute or a Tensor full of 0s will behave differently. 2. If the user ...

数据加载 在PyTorch中,数据加载可通过自定义的数据集对象。数据集对象被抽象为Dataset类,实现自定义的...
Fully Sharded Data Parallel (FSDP) 实现了 Optimizer + Gradient + Horizontal Model Sharding。 2.3 Optimizer State Sharding (OSS) 因为OSS是ZeroRedundancyOptimizer的源头,所以我们先看看其思路。OSS实现了与优化器内存相关的优化。像Adam这样的优化器通常需要保持动量、方差。即便可以使用FP16精度的参数和梯度进行训...

PyTorch now supports autoloading for out-of-tree device extensions, streamlining integration by eliminating the need for manual imports. This feature, enabled through the torch.backends entrypoint, simplifies usage by ensuring seamless extension loading, while allowing users to disable it via an environme...
(i.e, it started overfitting). This is because as a neural network gets deeper, the gradients from the loss function start to shrink to zero and thus the weights are not updated. This problem is known as the vanishing gradient problem. ResNet essentially solved this problem by using skip ...
