@Logan M I noticed the agent

@Logan M I noticed the agent implementations have been refactored by @jerryjliu0 , and when I try the usual OpenAI Agent implementation example provided in the docs, I can't seem to get it to work when I try astream_chat - just says STARTING TURN 1 and doesn't print anything beyond that. Am I doing something wrong, is there a new way to interact with things?

oh shoot, let me check on this -- I actually have no idea haha

LLogan M

Hmmm, this seemed to work for me

LLogan M

Just ran that same example from the notebook

LLogan M

maybe you ran into an API glitch?

LLogan M

It takes 60s to timeout by default

VVish

Yeah it looks like it was an API thing, thanks @Logan M !

Ran into a different issue shortly after, was testing chat_engine.astream_chat with chat_mode='openai', and got this error - ValueError: Streaming not supported for async

LLogan M

What's the full error?

VVish

Here's the stacktrace

VVish

I get -

Plain Text

=== Calling Function ===
Calling function: query_engine_tool with args: {
  "input": "Four lines about IMXRT1060RM"
}

and then the ValueError

LLogan M

Ah yes. That is an age-old issue.

We never setup the async + streaming in the RetrieverQueryEngine

I think it should technically be possible to implement now though

VVish

This is because the chat engine is using an underlying agent using the index as a query engine tool that is being called a retriever query engine, and that doesn't have async + streaming?

LLogan M

Yessir

LLogan M

Support could be added, but would take a touch of work
