The current yml code throws an error: ValueError: Please set lora_modules_to_save to [`embed_tokens`, `lm_head`] when using an adapter and changing the special tokens.
I added the required changes to resolve it
The strategy now supports configuring several fields: * The data field holding message arrays * the role and
content fields for each message * role mapping from source to target types
additionally this adds a sample llama3-8b instruct template using the chat template
