- Create a common class to use in all inheritance for states - Add a limit iterator that we can use in evals - Modify ArrowFileIterator behavior to not do arrow path inference if file_format='json' - Make EvalArgs valid - Move testing iterators to a common directory to allow usage in multiple test files - Make it so that SequenceIterator can take a None rng_state, to disable all rng ops (for eval mainly) Test Plan: - `pytest bytelatent` - `python -m bytelatent.train config=../internal-blt/configs/entropy_model.yaml logging.wandb=null eval=null`
