  how to use return function in streaminh

I found two similar unsolved discussions that might be relevant to your question:

1. How to return streamed response in a function ^[1].
2. How return LLMChain.run() stream data?? it did not store stream text in variable rather it just print?? ^[2].

Regarding your question, in Python, you cannot use return in a function that uses yield, as yield turns the function into a generator. If you want to accumulate data and return a final result after streaming, you should accumulate the data within the generator and then return it after the loop. However, this would require restructuring your code to separate the streaming and returning logic.

Here's a modified version of your function that accumulates the response and returns it after streaming:

async def generate_chat_responses(message):
    full_response = ""
    async for chunk in llm.astream(message):
        full_response += chunk.content  # Accumulate the chunk content into the full response
        yield f"{full_response}\n\n"
    return full_response  # This line will not be reached if using yield

If you need to return the accumulated response after streaming, you might need to call the generator and collect the results separately.
