Documentation: Add simple "getting started" examples

[clstaudt]

It would be great if the documentation included a few minimal working examples to get started with.

For example, it wasn't intuitive to me how to recreate something similar to the ChatGPT web interface.

You can use a ConversationChain, but you won't be able to customize the prompt or use tools it seems.

With LLMChain, I've almost managed to do a simple ChatGPT-style bot. You have to add a ConversationBufferMemory, and the following PromptTemplate:

The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.

Current conversation:

{history}
Human: {text}
AI:

This has a few flaws: you still cannot use tools, and does fairly often dream up the rest of the conversation:

but it might be a good starting point.

@notpushkin Thanks for the hint. This seems to behave like ChatGPT:

I think something like this should be included as a "Hello World" example in the documentation.

This is definitely something we are lacking at the moment. We improved a lot of the code and added many simpler options to experiment with so now might be a good time for us to add these examples.

@notpushkin the ConversationChain is essentially a LLMChain with a preconfigured prompt.
We are looking into improving the prompt experience(mainly by adding more control to input_variables and such).

In the case of the ConversationChain some improvements could be made. Keep an eye on #146.

Tangential: I was able to get tools working if I drop conversation memory:

langflow-tools-without-memory.json

Bad news: when I add any kind of memory to the mix, I get the following error:

Error: One input key expected got ['input', 'agent_scratchpad']

My best guess is, memory.save_context gets both input and agent_scratchpad and doesn't know which one of these it should save as the user message. Is there a way to get it working? (perhaps this could be a good cue for me to start a separate issue haha)

I hope that a template market can be realized, and everyone can contribute to the directory, just like the marketplaces of https://github.com/FlowiseAI/Flowise

I think a simple method to add tutorials would just create an examples folder. Then export some working code.

[notpushkin]

@frankjoshua I think that's what's going on in https://github.com/logspace-ai/langflow_examples? (e. g. see PR directly above your comment)

I think this examples repo needs some more visibility though.

[ogabrielluiz]

We plan on publishing something about them really soon. We are just working on the docs first.
