PyTorch提供给我们两个类: 抽象类是Python中必须执行的方法,所以我们可以通过创建一个子类来创建一个自定义数据集,该子类用来扩展 ‘数据集类(抽象类)’ 的功能。 使用PyTorch创建一个自定义类,我们通过创建子类来扩展数据集类的请求方法。在做这个的时候,我们的子类可以被传入PyTorchDataLoader对象。 我们将会使用fashi...
返回一个字典,键值对是key:metric 名字(string类型),value:metric 值(float类型)。 也就是教程4.1说的:直接调用metric的compute方法,传入labels和predictions即可得到metric的值。也只有这样做才能在训练时得到acc、F1等结果(具体指标根据不同任务来定) 为了构建我们的 compute_metric 函数,我们将依赖 🤗 Datasets 库...

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...
Python使用时候的相关实际问题: maya里面object是由tranform+shape 组成的 ← 特别容易被坑的部分 一开始这个[0]的意思看不懂,后来才意识到问题所在 sphere0=cmds.polySphere()[0] cmds.polyShpere 所return的不是object name的string,而是一个list,
