Harrison Chase	3bfe7cf467	Harrison/split schema dir (#7025 ) should be no functional changes also keep __init__ exposing a lot for backwards compat --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago
Zander Chase	b0859c9b18	Add New Retriever Interface with Callbacks (#5962 ) Handle the new retriever events in a way that (I think) is entirely backwards compatible? Needs more testing for some of the chain changes and all. This creates an entire new run type, however. We could also just treat this as an event within a chain run presumably (same with memory) Adds a subclass initializer that upgrades old retriever implementations to the new schema, along with tests to ensure they work. First commit doesn't upgrade any of our retriever implementations (to show that we can pass the tests along with additional ones testing the upgrade logic). Second commit upgrades the known universe of retrievers in langchain. - [X] Add callback handling methods for retriever start/end/error (open to renaming to 'retrieval' if you want that) - [X] Update BaseRetriever schema to support callbacks - [X] Tests for upgrading old "v1" retrievers for backwards compatibility - [X] Update existing retriever implementations to implement the new interface - [X] Update calls within chains to .{a]get_relevant_documents to pass the child callback manager - [X] Update the notebooks/docs to reflect the new interface - [X] Test notebooks thoroughly Not handled: - Memory pass throughs: retrieval memory doesn't have a parent callback manager passed through the method --------- Co-authored-by: Nuno Campos <nuno@boringbits.io> Co-authored-by: William Fu-Hinthorn <13333726+hinthornw@users.noreply.github.com>	1 year ago

Tim Conkling	c28990d871	StreamlitCallbackHandler (#6315 ) A new implementation of `StreamlitCallbackHandler`. It formats Agent thoughts into Streamlit expanders. You can see the handler in action here: https://langchain-mrkl.streamlit.app/ Per a discussion with Harrison, we'll be adding a `StreamlitCallbackHandler` implementation to an upcoming [Streamlit](https://github.com/streamlit/streamlit) release as well, and will be updating it as we add new LLM- and LangChain-specific features to Streamlit. The idea with this PR is that the LangChain `StreamlitCallbackHandler` will "auto-update" in a way that keeps it forward- (and backward-) compatible with Streamlit. If the user has an older Streamlit version installed, the LangChain `StreamlitCallbackHandler` will be used; if they have a newer Streamlit version that has an updated `StreamlitCallbackHandler`, that implementation will be used instead. (I'm opening this as a draft to get the conversation going and make sure we're on the same page. We're really excited to land this into LangChain!) #### Who can review? @agola11, @hwchase17	1 year ago

Zander Chase	928cdd57a4	[Breaking] Refactor Base Tracer(#4549 ) ### Refactor the BaseTracer - Remove the 'session' abstraction from the BaseTracer - Rename 'RunV2' object(s) to be called 'Run' objects (Rename previous Run objects to be RunV1 objects) - Ditto for sessions: TracerSessionV2 -> TracerSession - Remove now deprecated conversion from v1 run objects to v2 run objects in LangChainTracerV2 - Add conversion from v2 run objects to v1 run objects in V1 tracer	1 year ago
Zander Chase	4ee47926ca	Add on_chat_message_start (#4499 ) ### Add on_chat_message_start to callback manager and base tracer Goal: trace messages directly to permit reloading as chat messages (store in an integration-agnostic way) Add an `on_chat_message_start` method. Fall back to `on_llm_start()` for handlers that don't have it implemented. Does so in a non-backwards-compat breaking way (for now)	1 year ago
