I am getting this error when I try to download CIFAR100 and MNIST using the following line:

train_loader = torch.utils.data.DataLoader(
torchvision.datasets.CIFAR100(’/data/’, train=True, download=True,
transform=torchvision.transforms.Compose([
torchvision.transforms.ToTensor(),
torchvision.transforms.Normalize((0.4914, 0.4822, 0.4465), (0.2023, 0.1994, 0.2010)),
])),
batch_size=args.batch_size, shuffle=True)


train_loader = torch.utils.data.DataLoader(
torchvision.datasets.MNIST(’/data/’, train=True, download=True,
transform=torchvision.transforms.Compose([
torchvision.transforms.ToTensor(),
torchvision.transforms.Normalize(
(0.1307,), (0.3081,))
])),
batch_size=args.batch_size, shuffle=True)

Have anyone had the same error?
Running directly from my cpu works just fine, but in the virtual machine I get this Errno 13
Traceback CIFAR100
