* ipo-dpo trainer * fix missing abstract method * chatml template, grad checkpointing kwargs support * fix steps calc for RL and add dataloader kwargs * wip to fix dpo and start ppo * more fixes * refactor to generalize map fn * fix dataset loop and handle argilla pref dataset * set training args * load reference model on seperate gpu if more than one device * no auto upload to hub for dpo, don't add lora adapters to ref model for dpo * fixes for rl training * support for ipo from yaml * set dpo training args from the config, add tests * chore: lint * set sequence_len for model in test * add RLHF docs
