William FH	dcec133b85	[Core] Update Tracing Interops (#22318 ) LangSmith and LangChain context var handling evolved in parallel since originally we didn't expect people to want to interweave the decorator and langchain code. Once we get a new langsmith release, this PR will let you seemlessly hand off between @traceable context and runnable config context so you can arbitrarily nest code. It's expected that this fails right now until we get another release of the SDK	2 months ago

WU LIFU	86698b02a9	doc: fix wrong documentation on FAISS load_local function (#22310 ) ### Issue: #22299 ### descriptions The documentation appears to be wrong. When the user actually sets this parameter "asynchronous" to be True, it fails because the __init__ function of FAISS class doesn't allow this parameter. In fact, most of the class/instance functions of this class have both the sync/async version, so it looks like what we need is just to remove this parameter from the doc.

ccurme	af1f723ada	openai: don't override stream_options default (#22242 ) ChatOpenAI supports a kwarg `stream_options` which can take values `{"include_usage": True}` and `{"include_usage": False}`. Setting include_usage to True adds a message chunk to the end of the stream with usage_metadata populated. In this case the final chunk no longer includes `"finish_reason"` in the `response_metadata`. This is the current default and is not yet released. Because this could be disruptive to workflows, here we remove this default. The default will now be consistent with OpenAI's API (see parameter [here](https://platform.openai.com/docs/api-reference/chat/create#chat-create-stream_options)). Examples: ```python from langchain_openai import ChatOpenAI llm = ChatOpenAI() for chunk in llm.stream("hi"): print(chunk) ``` ``` content='' id='run-8cff4721-2acd-4551-9bf7-1911dae46b92' content='Hello' id='run-8cff4721-2acd-4551-9bf7-1911dae46b92' content='!' id='run-8cff4721-2acd-4551-9bf7-1911dae46b92' content='' response_metadata={'finish_reason': 'stop'} id='run-8cff4721-2acd-4551-9bf7-1911dae46b92' ``` ```python for chunk in llm.stream("hi", stream_options={"include_usage": True}): print(chunk) ``` ``` content='' id='run-39ab349b-f954-464d-af6e-72a0927daa27' content='Hello' id='run-39ab349b-f954-464d-af6e-72a0927daa27' content='!' id='run-39ab349b-f954-464d-af6e-72a0927daa27' content='' response_metadata={'finish_reason': 'stop'} id='run-39ab349b-f954-464d-af6e-72a0927daa27' content='' id='run-39ab349b-f954-464d-af6e-72a0927daa27' usage_metadata={'input_tokens': 8, 'output_tokens': 9, 'total_tokens': 17} ``` ```python llm = ChatOpenAI().bind(stream_options={"include_usage": True}) for chunk in llm.stream("hi"): print(chunk) ``` ``` content='' id='run-59918845-04b2-41a6-8d90-f75fb4506e0d' content='Hello' id='run-59918845-04b2-41a6-8d90-f75fb4506e0d' content='!' id='run-59918845-04b2-41a6-8d90-f75fb4506e0d' content='' response_metadata={'finish_reason': 'stop'} id='run-59918845-04b2-41a6-8d90-f75fb4506e0d' content='' id='run-59918845-04b2-41a6-8d90-f75fb4506e0d' usage_metadata={'input_tokens': 8, 'output_tokens': 9, 'total_tokens': 17} ```	2 months ago

hmasdev	bbd7015b5d	core[patch]: Add `TypeError` handler into `get_graph` of `Runnable` (#19856 ) # Description ## Problem `Runnable.get_graph` fails when `InputType` or `OutputType` property raises `TypeError`. - `003c98e5b4/libs/core/langchain_core/runnables/base.py (L250-L274)` - `003c98e5b4/libs/core/langchain_core/runnables/base.py (L394-L396)` This problem prevents getting a graph of `Runnable` objects whose `InputType` or `OutputType` property raises `TypeError` but whose `invoke` works well, such as `langchain.output_parsers.RegexParser`, which I have already pointed out in #19792 that a `TypeError` would occur. ## Solution - Add `try-except` syntax to handle `TypeError` to the codes which get `input_node` and `output_node`. # Issue - #19801 # Twitter Handle - [hmdev3](https://twitter.com/hmdev3) --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	2 months ago
