I've added food-101 to the RECIPES

Have you tested loading this into a data container and can you check that checkblock(getobs(data, 1), blocks) is true?

[Chandu-4444]

Oh, I forgot about tests. I'll check and will update the tests.

You don't need to write test cases for this, just test it manually. Unfortunately, we can't test every dataset recipe all the time since then CI would have to download every dataset (and just this one is a few GB I think)

[Chandu-4444]

Okay, I'll test it manually and will update it here then 👍

Yeah, it returned true.

Thanks for checking!
