LangChain CallbackHandler #6890

tconkling · 2023-06-22T21:01:08Z

Add our LangChain StreamlitCallbackHandler (also present in the LangChain repo), along with some Streamlit-specific tests.

When used from LangChain, this callback handler is an "auto-updating API". That is, a LangChain user can do

from langchain.callbacks.streamlit import StreamlitCallbackHandler
callback = StreamlitCallbackHandler(st.container())

and if they have a recent version of Streamlit installed in their environment, Streamlit's copy of the callback handler will be used instead of the LangChain-internal one. This allows us to update and improve StreamlitCallbackHandler independently of LangChain, and LangChain users of the callback will see those changes automatically.

In other words, while StreamlitCallbackHandler is not part of the public Streamlit st API, it is part of LangChain's public API, and we need to keep it stable. (This PR contains a few tests that assert its API stability.)

Overall, this LGTM 👍

I mostly have some questions to clarify some aspects. Here are also some more higher-level questions:

Do you have an example of how I could save the latest state to the session state and recreate the UI after a rerun? Is it doable with the current implementation without running into stale element issues?
Do we plan to add the public API for this also to our API reference?
Would it make sense to remove the implementation from langchain in a couple of months to prevent redundancy/maintenance overhead? This would mean that it would always require a certain min version of Streamlit, but I think that's fine to do once this feature in Streamlit core is part of most Streamlit installations.

Another step after the PR is merged (maybe for next Quarter): It probably would be useful to get some of the mutable expander features somehow into our st.expander implementation (or a new expander component) since showing these intermediate thoughts is something useful also outside of langchain.

+class MutableExpander:


nit: a nice-to-have would be some unit tests for MutableExpander. Thought, StreamlitCallbackHandlerTest is covering that on a higher level, so it's not fully necessary. But it would make it easier to potentially reuse MutableExpander for other intermediate thought use cases/frameworks as well.

I'd prefer that MutableExpander not be adopted as a general use tool, because it is a hack (and quite inefficient). The proper long-term solution is for us to develop proper first-class elements and widgets that natively support the sort of mutation that MutableExpander simulates by rebuilding itself from scratch whenever its label changes.

(I added a note to the class to this effect)

* develop: Add color_util.py, which will be used by native charts in next few PRs. (streamlit#6826)

Answers to your questions, @lukasmasuch:

Do you have an example of how I could save the latest state to the session state and recreate the UI after a rerun? Is it doable with the current implementation without running into stale element issues?

No, this isn't currently supported. (It's true that you could accomplish it with the "capturing callback handler", but I think we'd want to put a bunch more thought into that before making it part of the API.)

Do we plan to add the public API for this also to our API reference?

I don't think so (but cc @sfc-gh-jcarroll for clarification). The idea is that StreamlitCallbackHandler is actually a part of LangChain, and not "officially" part of Streamlit.

The reason we include it in Streamlit is so that we can update the implementation (e.g. with new LLM-friendly elements, if we add some down the road) without submitting new PRs to the LangChain project. LangChain's copy of StreamlitCallbackHandler tries to import and use the Streamlit-internal version of the class (and falls back to its own built-in implementation it's used in an older version of Streamlit that doesn't have it).

Would it make sense to remove the implementation from langchain in a couple of months to prevent redundancy/maintenance overhead? This would mean that it would always require a certain min version of Streamlit, but I think that's fine to do once this feature in Streamlit core is part of most Streamlit installations.

We want StreamlitCallbackHandler to live "forever" in LangChain itself (so this original v1 implementation will remain in that repo); and we also want to be able to update StreamlitCallbackHandler with the latest-and-greatest Streamlit features without submitting PRs against LangChain - so the idea is that this feature will exist in both repos. (This is why it's important that our implementation maintain API compatibility with the v1 LangChain implementation.)

Do we plan to add the public API for this also to our API reference?

I think we should add a page somewhere in our docs that points to the relevant langchain docs for discoverability, but not try to replicate the full API reference etc.

It probably would be useful to get some of the mutable expander features somehow into our st.expander implementation (or a new expander component)

Big Agree!!! Actively working on this, trying to figure out who can partner on it with me in the coming weeks beyond Tim :)

…o bump our min version

Add our LangChain `StreamlitCallbackHandler` (also present in the [LangChain repo](langchain-ai/langchain#6315)), along with some Streamlit-specific tests. When used from LangChain, this callback handler is an "auto-updating API". That is, a LangChain user can do ```python from langchain.callbacks.streamlit import StreamlitCallbackHandler callback = StreamlitCallbackHandler(st.container()) ``` and if they have a recent version of Streamlit installed in their environment, Streamlit's copy of the callback handler will be used instead of the LangChain-internal one. This allows us to update and improve `StreamlitCallbackHandler` independently of LangChain, and LangChain users of the callback will see those changes automatically. In other words, while `StreamlitCallbackHandler` is not part of the public Streamlit `st` API, it _is_ part of LangChain's public API, and we need to keep it stable. (This PR contains a few tests that assert its API stability.)
