totensor方法和normalize方法 数值映射和归一化 待办 ToTensor是指把PIL.Image(RGB) 或者numpy.ndarray(H x W x C) 从0到255的值映射到0到1的范围内,并转化成Tensor格式. 2.Normalize(mean,std)是通过下面公式实现数据归一化 channel=(channel-mean)/std https://www.jianshu.com/p/8da9b24b2fb6 这属于数据预处理

(1)Reset.css 简介:在HTML标签在浏览器里有默认的样式,例如 p 标签有上下边距,strong标签有字体加粗样式,em标签有字体倾斜样式.不同浏览器的默认样式之间也会有差别,例如ul默认带有缩进的样式,在IE下,它的缩进是通过margin实现的,而Firefox下,它的缩进是由padding实现的.在切换页面的时候,浏览器的默认样式往往会给我们带来麻烦,影响开发效率.所以解决的方法就是一开始就将浏览器的默认样式全部去掉,更准确说就是通过重新定义标签样式.“覆盖”浏览器的CSS默认属
