The torchvision datasets return pixelvalues in range 0-255 as @vmirly1 says, so yeah, there seems to be a typo of some sort in the tutorial maybe?
The transforms.ToTensor() in your transform will convert it to range 0-1 (documentation: https://pytorch.org/docs/master/torchvision/transforms.html#torchvision.transforms.ToTensor 23)
The literal formulation “PILImage fo range [0, 1]” means that the individual pixel values are between those two values.
Hope this helped!
