1. torch.renorm(input, p, dim, maxnorm, out=None) → Tensor Returns a tensor where each sub-tensor of input along dimension dim is normalized such that the p-norm of the sub-tensor is lower than the value maxnorm. 解释:返回一个张量,包含规范化后的各个子张量,使得沿着dim维划分的各子张
[学习源]Tutorials > Deep Learning with PyTorch: A 60 Minute Blitz > Training a Classifier 本文相当于对上面链接教程中自认为有用部分进行的截取.翻译和再注释.便于日后复习.修正和补充. 边写边查资料的过程中猛然发现这居然有中文文档--不过中文文档也是志愿者翻译的,仅仅是翻译,也没有对知识点的扩充,不耽误我写笔记.这篇笔记就继续写下去吧.附PyTorch 中文教程 & 文档 > 训练分类器 一.准
We perform image classification, one of the computer vision tasks deep learning shines at. As training from scratch is unfeasible in most cases (as it is very data hungry), we perform transfer learning using ResNet-50 pre-trained on ImageNet. We get
