Zander Chase	204a73c1d9	Use client from LCP-SDK (#5695 ) - Remove the client implementation (this breaks backwards compatibility for existing testers. I could keep the stub in that file if we want, but not many people are using it yet - Add SDK as dependency - Update the 'run_on_dataset' method to be a function that optionally accepts a client as an argument - Remove the langchain plus server implementation (you get it for free with the SDK now) We could make the SDK optional for now, but the plan is to use w/in the tracer so it would likely become a hard dependency at some point.	1 year ago

berkedilekoglu	f907b62526	Scores are explained in vectorestore docs (#5613 ) # Scores in Vectorestores' Docs Are Explained Following vectorestores can return scores with similar documents by using `similarity_search_with_score`: - chroma - docarray_hnsw - docarray_in_memory - faiss - myscale - qdrant - supabase - vectara - weaviate However, in documents, these scores were either not explained at all or explained in a way that could lead to misunderstandings (e.g., FAISS). For instance in FAISS document: if we consider the score returned by the function as a similarity score, we understand that a document returning a higher score is more similar to the source document. However, since the scores returned by the function are distance scores, we should understand that smaller scores correspond to more similar documents. For the libraries other than Vectara, I wrote the scores they use by investigating from the source libraries. Since I couldn't be certain about the score metric used by Vectara, I didn't make any changes in its documentation. The links mentioned in Vectara's documentation became broken due to updates, so I replaced them with working ones.

Finally, we'd love to show appreciation for your contribution - if you'd like us to shout you out on Twitter, please also include your handle! --> #### Description This PR is mainly to integrate open source version of ClickHouse as Vector Store as it is easy for both local development and adoption of LangChain for enterprises who already have large scale clickhouse deployment. ClickHouse is a open source real-time OLAP database with full SQL support and a wide range of functions to assist users in writing analytical queries. Some of these functions and data structures perform distance operations between vectors, [enabling ClickHouse to be used as a vector database](https://clickhouse.com/blog/vector-search-clickhouse-p1). Recently added ClickHouse capabilities like [Approximate Nearest Neighbour (ANN) indices](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/annindexes) support faster approximate matching of vectors and provide a promising development aimed to further enhance the vector matching capabilities of ClickHouse. In LangChain, some ClickHouse based commercial variant vector stores like [Chroma](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/chroma.py) and [MyScale](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/myscale.py), etc are already integrated, but for some enterprises with large scale Clickhouse clusters deployment, it will be more straightforward to upgrade existing clickhouse infra instead of moving to another similar vector store solution, so we believe it's a valid requirement to integrate open source version of ClickHouse as vector store. As `clickhouse-connect` is already included by other integrations, this PR won't include any new dependencies. #### Before submitting <!-- If you're adding a new integration, please include: 1.

Tomaz Bratanic	a0ea6f6b6b	Cypher search: Check if generated Cypher is provided in backticks (#5541 ) # Check if generated Cypher code is wrapped in backticks Some LLMs like the VertexAI like to explain how they generated the Cypher statement and wrap the actual code in three backticks: ![Screenshot from 2023-06-01 08-08-23](https://github.com/hwchase17/langchain/assets/19948365/1d8eecb3-d26c-4882-8f5b-6a9bc7e93690) I have observed a similar pattern with OpenAI chat models in a conversational settings, where multiple user and assistant message are provided to the LLM to generate Cypher statements, where then the LLM wants to maybe apologize for previous steps or explain its thoughts. Interestingly, both OpenAI and VertexAI wrap the code in three backticks if they are doing any explaining or apologizing. Checking if the generated cypher is wrapped in backticks seems like a low-hanging fruit to expand the cypher search to other LLMs and conversational settings.	1 year ago

Ralph Schlosser	74f8e603d9	Addresses GPT4All wrapper model_type attribute issues #5720 . (#5743 ) Fixes #5720. A more in-depth discussion is in my comment here: https://github.com/hwchase17/langchain/issues/5720#issuecomment-1577047018 In a nutshell, there has been a subtle change in the latest version of GPT4Alls Python bindings. The change I submitted yesterday is compatible with this version, however, this version is as of yet unreleased and thus the code change breaks Langchain's wrapper under the currently released version of GPT4All.

Nathan Azrak	26ec845921	Raise an exception in MKRL and Chat Output Parsers if parsing text which contains both an action and a final answer (#5609 ) Raises exception if OutputParsers receive a response with both a valid action and a final answer Currently, if an OutputParser receives a response which includes both an action and a final answer, they return a FinalAnswer object. This allows the parser to accept responses which propose an action and hallucinate an answer without the action being parsed or taken by the agent. This PR changes the logic to: 1. store a variable checking whether a response contains the `FINAL_ANSWER_ACTION` (this is the easier condition to check). 2. store a variable checking whether the response contains a valid action 3. if both are present, raise a new exception stating that both are present 4. if an action is present, return an AgentAction 5. if an answer is present, return an AgentAnswer 6. if neither is present, raise the relevant exception based around the action format (these have been kept consistent with the prior exception messages) Disclaimer: * Existing mock data included strings which did include an action and an answer. This might indicate that prioritising returning AgentAnswer was always correct, and I am patching out desired behaviour? @hwchase17 to advice. Curious if there are allowed cases where this is not hallucinating, and we do want the LLM to output an action which isn't taken. * I have not passed `send_to_llm` through this new exception Fixes #5601 ## Who can review?

Ricardo Reis	33ea606f45	Update youtube.py - Fix metadata validation error in YoutubeLoader (#5479 ) This commit addresses a ValueError occurring when the YoutubeLoader class tries to add datetime metadata from a YouTube video's publish date. The error was happening because the ChromaDB metadata validation only accepts str, int, or float data types. In the `_get_video_info` method of the `YoutubeLoader` class, the publish date retrieved from the YouTube video was of datetime type. This commit fixes the issue by converting the datetime object to a string before adding it to the metadata dictionary. Additionally, this commit introduces error handling in the `_get_video_info` method to ensure that all metadata fields have valid values. If a metadata field is found to be None, a default value is assigned. This prevents potential errors during metadata validation when metadata fields are None. The file modified in this commit is youtube.py. # Your PR Title (What it does) <!-- Thank you for contributing to LangChain! Your PR will appear in our release under the title you set.
