HTTPError：HTTP 错误 403：使用 pytorch 下载 MNIST 数据集时被禁止

Question

Please help me to solve this problem

I am using colab notebook and loaded it to my drive. When I run the following code to get the dataset using the following code:

import torch
import torch.nn as nn
import torchvision
import torchvision.transforms as transforms

train_dataset = torchvision.datasets.MNIST(root="/content/drive/MyDrive/Colab Notebooks/pytorch/Data",
                                           train=True, 
                                           transform=transforms.ToTensor(),
                                           download=True
                                           )

This is my error

i also faced similar issue and i resolve it by normalizing the data not sure though why it works try this.

enter code heretrain_dataset = torchvision.datasets.MNIST(root="/content/drive/MyDrive/Colab Notebooks/pytorch/Data",
                                       train=True, 
                                       transform=transforms.Compose([transforms.ToTensor(),
                                                transforms.Normalize((0.5,), (0.5,))]),
                                       download=True
                                       )
