Python Pytorch torchvision FasionList数据集赢得'；t载荷

我在一台Windows10机器上运行，使用空闲模式。下面是一些Pytorch教程。在我尝试下载FashionList数据集之前，一切正常

我首先用pip安装了torchvision软件包

pip install torchvision===0.9.1+cu111 -f https://download.pytorch.org/whl/torch_stable.html

下面是我安装的软件包

我尝试运行以下脚本

import torch
from torch.utils.data import Dataset
from torchvision import datasets
from torchvision.transforms import ToTensor
import matplotlib.pyplot as plt


training_data = datasets.FashionMNIST(
    root="C:/../../../Python/LearningPytorch/data",
    train=True,
    download=True,
    transform=ToTensor()
    
)

test_data = datasets.FashionMNIST(
    root="C:/../../../Python/LearningPytorch/data",
    train=False,
    download=True,
    transform=ToTensor()
)

一切似乎都以预期的产出开始

大约半个小时，在大约百分之五十的下载量下，它失败了。我有很好的互联网，在整个过程中以500 Mbps的速度下载

我收到以下错误消息

下载的gzip文件的一部分可以在C:…\Python\LearningPytorch\data\fashionlist\raw中找到 data/fashionlist/raw/train-images-idx3-ubyte.gz

我尝试从中下载，只替换下载过程中创建的文件夹结构中的数据。这也不起作用

这里出了什么问题？
