Thanks for the patch, @juncongmoo!

Unfortunately, the from_raw_prompt method that we released was only half implemented. It needs to create an instance of Conversation, passing a human id and a bot id and set the new prompt.

    @classmethod
    def from_raw_prompt(cls, human_id, bot_id, prompt):
        convo = Conversation(human_id, bot_id)
        convo._prompt = prompt
        return convo
