前言:本文是Redis吊打面试官系列的数据结构原理专题,介绍列表list的底层实现 前提认识:Redis的list底层是双向链表 1、链表节点结构 2、list结构 3、总体结构 总结: 链表被广泛用于实现Redis的各种功能,比如列表键、发布订阅、慢查询、监视器等。 通过为链表设置不太的类型特定函数,Redis的链表可以用于保存各种不太类型...

一般来说,需要将tensor转变为numpy类型的数组从而保存图片,这样的过程比较繁琐,Pytorch提供了save_image()函数,可直接将tensor保存为图片,若tensor在cuda上也会移到CPU中进行保存。 ) 参数: tensor (Tensor or list): Image to be saved. If given a mini-batch tensor, saves th...win...
