Thanks for catching and fixing this! I just had one comment.

Sorry this is a bit of a misleading TODO. The intent was to come back and add a link to the recipes page (https://pytorch.org/torchtune/main/deep_dives/recipe_deepdive.html) from within the error message itself - not the comment in the file. Can you update based on this extra context?

[j-dominguez9]

Sorry about that, all set now. I didn't have any reference of style, since the other init.py files don't have these error messages, but I added the url in a new line, as requested.
