Thanks for replying but in Online DPO trainer

if self.control.should_save:
self._save_checkpoint(model, trial=None, metrics=metrics)
self.control = self.callback_handler.on_save(self.args, self.state, self.control)
raise error:'OnlineDPOTrainer' object has no attribute 'model_wrapped'

Thanks for reporting, fixed in #1946
