i have the same issue, have you resolved it yet ?

Same issue here

I ran into this issue as well and resolved it by downloading the datasets from torchvision and pickling them manually.

Here's my code in case it's helpful (put it somewhere before the cell that visualizes svhn and cifar10 data).

import torchvision
import torchvision.transforms as transforms

def get_svhn_dataset():
  data_dir = get_data_dir(2)
  train_dataset = torchvision.datasets.SVHN(root=data_dir, split="train", download=True, transform=transforms.ToTensor())
  test_dataset = torchvision.datasets.SVHN(root=data_dir, split="test", download=True, transform=transforms.ToTensor())
  data = {"train": train_dataset.data.transpose((0, 2, 3, 1)), "test": test_dataset.data.transpose(0, 2, 3, 1)}
  with open(join(data_dir, "svhn.pkl"), "wb") as file:
    pickle.dump(data, file)

def get_cifar10_dataset():
  data_dir = get_data_dir(2)
  train_dataset = torchvision.datasets.CIFAR10(root=data_dir, train=True, download=True, transform=transforms.ToTensor())
  test_dataset = torchvision.datasets.CIFAR10(root=data_dir, train=False, download=True, transform=transforms.ToTensor())
  data = {"train": train_dataset.data, "test": test_dataset.data}
  with open(join(data_dir, "cifar10.pkl"), "wb") as file:
    pickle.dump(data, file)

get_svhn_dataset()
get_cifar10_dataset()
