FunctionTool

Right now, function tools can only be used with agents (in addition to query engine tools)

Thanks. I'll try it today itself and let you know the feedback! Apprecite it.

I am trying to use FuncTools without OpenAI agent. I wish to use Llama 2 instead.

do you know how to get around this?

@Logan M is it possible to do something like this or do I have to use openai agent with functools?

You have to use either an openai agent or react agent yea

Maybe a PR could generalize this a little better

Basically, i m tryin to have a list of functool and other query engine tools... all being selectively chosen using a Router

I'll check reactagent

If you are using openai, I highly recommend the openai agent. Otherwise, yea react agent wouldn't be too bad either.

Like I mentioned too, a but of a refactor could extend the router engine to work for this, if you had time

Just need to modify it to work with any tool rather than specifically query engines

https://github.com/jerryjliu/llama_index/blob/d59ed48a08a5e5fd9d3361250beeb9fbfaf8cd50/llama_index/query_engine/router_query_engine.py#L99

sure... i'll check this.. thanks

i m still very new to Llamaindex... just reading all the help docs and starting to build things...

I read the code you shared, one way could be to define self._query_engine in Functool and define query function in Functool which jsut sends the response by calling the function set in constructor

https://github.com/jerryjliu/llama_index/blob/d59ed48a08a5e5fd9d3361250beeb9fbfaf8cd50/llama_index/query_engine/router_query_engine.py#L145

then we don't have to touch RouterQueryEngine... FuncTool will pretty much look like any other query engine

I see both query-engine and functiontool can be adjusted as LangChain tool.. so that's probably another way for now
