anaconda - 当我尝试执行 Pytorch 代码时出现 Win Error 5

问题描述

我是 Anaconda 的新手。我试图在 anaconda 中执行 Pytorch 对抗神经网络。它显示了一些我不知道的错误。这是下载数据集的代码

# MNIST Test dataset and dataloader declaration
test_loader = torch.utils.data.DataLoader(datasets.MNIST('../data', train=False, download=True, transform=transforms.Compose([
            transforms.ToTensor(),])),batch_size=1, shuffle=True)

这是我收到的错误消息：

     PermissionError                           Traceback (most recent call last)
     <ipython-input-4-59310f6a37f8> in <module>

223         mkdir(name, mode)
224     except OSError:
225         # Cannot rely on checking for EEXIST, since the operating system

PermissionError: [WinError 5] Access is denied: '../data' .

解决方案

如何将其更改'../data'为另一个目录，例如'/Users/***/Downloads/data'或其他地方。
