Combination of a Vectorstore with a ChatBot

[BeatArnet]

I would like to implement a "py-pdf-loader" together with a "ChatBot with memory and prompt". Has anybody made an example to import within langflow?

Hey @BeatArnet, you can click on the Import button -> Examples and:

[BeatArnet]

Yes, I have already done that. The only thing I'm missing is the combination with a ChatBot that has a memory. The PDF Loader example has no memory. Unfortunately, I can't dock to a previous question. That's why I would like a combination with the Memory ChatBot.

Oh. I see.. I'll see what I can do.

@BeatArnet Did you have any luck with this?

[ogabrielluiz]

I have yet to find an easy way of doing this in langflow. What I thought was to create a new VectorStoreAgent node. Do you have an example LangChain project for me to reference?

[BeatArnet]

Unfortunately no. I can find several Langchain examples to process and query a PDF or a text file, almost all of them are called chatbots, but none of them has a memory.
