* feat: add cut_cross_entropy * fix: add to input * fix: remove from setup.py * feat: refactor into an integration * chore: ignore lint * feat: add test for cce * fix: set max_steps for liger test * chore: Update base model following suggestion Co-authored-by: Wing Lian <wing.lian@gmail.com> * chore: update special_tokens following suggestion Co-authored-by: Wing Lian <wing.lian@gmail.com> * chore: remove with_temp_dir following comments * fix: plugins aren't loaded * chore: update quotes in error message * chore: lint * chore: lint * feat: enable FA on test * chore: refactor get_pytorch_version * fix: lock cce commit version * fix: remove subclassing UT * fix: downcast even if not using FA and config check * feat: add test to check different attentions * feat: add install to CI * chore: refactor to use parametrize for attention * fix: pytest not detecting test * feat: handle torch lower than 2.4 * fix args/kwargs to match docs * use release version cut-cross-entropy==24.11.4 * fix quotes * fix: use named params for clarity for modal builder * fix: handle install from pip * fix: test check only top level module install * fix: re-add import check * uninstall existing version if no transformers submodule in cce * more dataset fixtures into the cache --------- Co-authored-by: Wing Lian <wing.lian@gmail.com> Co-authored-by: Wing Lian <wing@axolotl.ai>
