NanoCode012 682a9cf79b Fix: add delinearization and make qlora work with fsdp2 (#2515)
* fixes for delinearization, and make qlora work with fsdp2

* Add back mistakenly removed lm_eval

* typo [skip ci]

* patch evals for torch.compile + fsdp2

* also check torch_compile w fsdp2

* lots of fixes for flex attn with llama4

* fix patch check and patch llama4 too

* attempt to make the patches stick

* use transformers 4.51.2

* update configs and README for llama4

* remove torch.compile for CI test

* cleanup any existing singletons

* set singleton cache to None instead of deleting

* use importlib reload with monkeypatch

* don't worry about transformers version, mark inputs with grads, fix regex

* make sure embeds aren't on cpu

* logging and mem improvements

* vllm version and add to docker, make sure to save processor on conversion

* fix ambiguous tensor bool check

* fix vllm to not use v1, upgrade hf transformers

* fix tests

* make flex_attn_compile_kwargs configurable, since this depends on model params
