* Add chat_template.argilla_chat support for DPO datasets
Creates a new chat_template.argilla_chat prompt strategy for handling
DPO datasets where chosen/rejected fields contain full conversations
(messages + final response), following the pattern of chatml.argilla_chat
and llama3.argilla_chat.
- Add argilla_chat() function to chat_template.py
- Add chat_template.argilla_chat to RLHF documentation
- Add test coverage for argilla_chat with multiple tokenizers
Dataset format:
{
"chosen": [
{"role": "user", "content": "..."},
{"role": "assistant", "content": "..."}
],
"rejected": [
{"role": "user", "content": "..."},
{"role": "assistant", "content": "..."}
]
}
* Fix chat_template.argilla_chat return value contract and add docstring
- Return (transform_fn, dataset_kwargs) tuple instead of bare transform_fn
- Add remove_columns specification for field_chosen and field_rejected
- Add comprehensive docstring with Args/Returns sections
- Update tests to unpack tuple return value
Addresses PR feedback to maintain consistency with chat_template.default()
and properly specify columns to remove after dataset transformation.
* Update tests/prompt_strategies/test_dpo_chat_templates.py
