# <div align="center"><strong>PyTorch Scatter</strong></div>
## 简介
PyTorch Scatter由一个小型扩展库组成,
该扩展库包含用于PyTorch的高度优化的稀疏更新(分散和分段)操作,这些操作在主包中丢失。分散和分段运算可以粗略地
描述为基于给定“
群
索引”张量的归约
运算。分段运算需要对“组索引”张量进行排序,而分散运算则不受这些要求的约束。PyTorch Scatter官方github地址:

PyTorch Scatter由一个小型扩展库组成,
专为PyTorch设计,提供了一系列高度优化的稀疏更新(scatter和segment)操作,这些操作在主包中是缺失的。Scatter和segment操作可以大致
描述为基于给定“
组
索引”张量的归约
操作。Segment操作要求“组索引”张量是有序的,而scatter操作则不受此要求限制。DAS软件栈中的PyTorch Scatter版本,不仅保证了该组件 核心功能在DCU加速卡的可用性,还针对DCU特有的硬件架构进行了深度定制优化,这使得开发者能够以极低的成本,轻松实现应用程序在DCU加速卡上的快速迁移和性能提升。目前已适配支持Pytorch1.13,Pyotrch2.1,Pytorch2.3。
