I think it may make more sense to move this new language_model_lib code under algorithms/chat or something like that, and you could put the align_system/language_model_lib/llama_2_kdma_predicting_adm.py file directly under algorithms. It may also make sense to rename llm_chat_baseline.py to llama_2_chat_baseline.py if it really is specific to llama 2.
