首先自定义Dataset必须要写一个继承from torch.utils.data import Dataset的类,其中除了init方法以外还有两个方法,__getitem__()和__len__(),可以这么理解:在使用pytorch自带的Dataloader把Dataset包裹起来调用的时候,会认为这个Dataset一共有的数据量就是__len__()的返回值,比如Dataloader的batch参数为8,即一次读取...

We will be using that to simulate simple random processes,but we’ll also take a look at some other tools the Python has to generate random numbers. 我们将使用它来模拟简单的随机过程,但我们还将看看Python生成随机数的其他一些工具。 Let’s see how we can use the random choice function to car...
