网站设计一般多长时间长治网上制作网站

在查看pytorch官方文档的时候，在这里链接中https://pytorch.org/tutorials/beginner/basics/data_tutorial.html的Creating a Custom Dataset for your files章节，有提到要自定义数据集，需要用到实际的图片和标签。

在网上找了半天没找到，写了一个脚本将图片和标签文本下载到本地。

test_data = datasets.FashionMNIST(root="data",train=False,download=True,transform=ToTensor(),
)# 写入到本地
