- 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`
Summary:
- Refactor local model configs to be separate and clearer
- Add attention arguments and correct which attention is used in local models
- Preparation for being able to have an entropy train script
- Fix failing unit tests
