Is it possible to inject previous history?

[tyler-suard-parker]

Hello. My frontend returns the last 4 exchanges with a chatbot. I was wondering if there is a way to initialize an agent using that prior history.

@tyler-suard-parker ,

Yes, you can update the history of agents.

• loop through the history object
• call agent.send(message, receiver, request_reply=False) . This adds the particular message to the agent history without triggering a reply.
• finally, when you call initiate_chat, ensure you set clear_history=False ... initiate_chat(clear_history=False)

Some pseudo code below

user_proxy = autogen.UserProxyAgent ..
assistant = autogen.AssistantAgent ...

for message in history:
    user_proxy.send(message, assistant, request_reply=False) 
    # you can also send from assistant to user_proxy depending on your use case

user_proxy.initiate_chat(assistant, message=message, clear_history=False)

how about groupchat? how to handle the chat history?

[jacinli]

I have a way to resolve history in GroupChat, but it will be a bit imperfect. You can write previous conversations into a history list.
For example:
history_after_summary_str = " ".join([item["content"] for item in history]) GroupChat.DEFAULT_INTRO_MSG = history_after_summary_str
Then you can use this writing method to initialize DEFAULT_INTRO_MSG of GroupChat, and set the send_introductions attribute in GroupChat to True.

I now think of a better way, which is to not need to import the introduction into the group chat, but also to send my previous conversation records in advance. Here is my sample code, hope it helps.
` for msg in history:
if msg["role"] == 2:

                for assistant in assistants:
                    await manager.a_send(msg["content"], recipient=assistant, request_reply=False, silent=True)
            # else:
            #     await manager.a_send(msg["content"], recipient=user_proxy, request_reply=False, silent=False)      
        #Send previous conversation information to manager before initchat 
        await user_proxy.a_initiate_chat(
            silent=True,
            recipient=manager,
            clear_history=False,
            message=message,
        )`

You can now resume a group chat from a previous session: https://microsoft.github.io/autogen/docs/topics/groupchat/resuming_groupchat

how about groupchat? how to handle the chat history?

Try this:
https://clintgoodman27.medium.com/a-practical-guide-for-using-autogen-in-software-applications-8799185d27ee
but with one change : await user_proxy.a_initiate_chat(manager, message=message, clear_history=False)
ensure clear_history is set to False
I have tried, it works for me

[afogarty85]

Anyone got an example of how we can include chat history clearly in a groupchat scenario?

[r4881t]

@afogarty85 - Something like this will work in a generic manner, providing an easy interface for user - agent/GroupChat/SoM chat history
