Questions/Notes

• I noticed in the fully-fine-tune tests, the tolerance changed from rtol=1e-4 to rtol=1e-3, I have not changed the rtol values in any of the recipes I changed, is this okay or should the tolerance threshold increase for the others too?
• I ran a few tests on my machine and got quite a few OOMs. Not sure if I will be able to change the expected loss so they are currently either commented out or marked with a "# TODO". I may need some help running the tests in case I'm unable to, however I could work around this by lowering the vocab size to fix this if that is okay?
• I committed an unfinished version of test_dpo_distributed on accident.

@krammnic Please let me know if you notice any bugs or errors or have any pointers for me. I should have the remaining recipes done within the next couple days, sorry again the long wait! life's been pretty crazy haha.
