"Corrupt file!" When downloading cifar10 and cifar100

[whipson]

Trying to get cifar10 data using the helper cifar10_dataset and it fails with "Corrupt file!". Not sure how to proceed from here.

library(dplyr)
library(torch)
library(torchvision)

transformed_cifar10 <- cifar10_dataset(".", 
                                       train = TRUE, 
                                       download = TRUE)

Output:

Run `rlang::last_error()` to see where the error occurred.

It looks like the file md5 hash has changed on the server: https://github.com/mlverse/torchvision/blob/main/R/dataset-cifar.R#L22

And for security reasons we don't try to do anything else with it. We will need to update it and do a patch release of torchvision.
