Maybe this PR fits better in https://github.com/mlverse/torchdatasets (I am not the maintainer though, so maybe @dfalbel has a different opinion)

Thank you, The instructions on https://github.com/rstats-gsoc/gsoc2025/wiki/torchvision-in-R-improvements were not clear as it didn't state which repository to fork. Sorry for the trouble

Hello @Prateek0xeo,

Many thanks for this contribution !

@sebffischer is right, the perfect place for your P.R. is torchdatasets.
Would you be kind enough to make the same P.R. in torchdatasets/pulls ?

[Prateek0xeo]

Sure!
