wenmeng zhou	bb7ac9edb5	add dashscope text embedding (#5929 ) #### What I do Adding embedding api for [DashScope](https://help.aliyun.com/product/610100.html), which is the DAMO Academy's multilingual text unified vector model based on the LLM base. It caters to multiple mainstream languages worldwide and offers high-quality vector services, helping developers quickly transform text data into high-quality vector data. Currently supported languages include Chinese, English, Spanish, French, Portuguese, Indonesian, and more. #### Who can review?

Akhil Vempali	d7d629911b	feat: ✨ Added filtering option to FAISS vectorstore (#5966 ) Inspired by the filtering capability available in ChromaDB, added the same functionality to the FAISS vectorestore as well.

German Martin	736a1819aa	LOTR: Lord of the Retrievers. A retriever that merge several retrievers together applying document_formatters to them. (#5798 ) "One Retriever to merge them all, One Retriever to expose them, One Retriever to bring them all and in and process them with Document formatters." Hi @dev2049! Here bothering people again! I'm using this simple idea to deal with merging the output of several retrievers into one. I'm aware of DocumentCompressorPipeline and ContextualCompressionRetriever but I don't think they allow us to do something like this. Also I was getting in trouble to get the pipeline working too. Please correct me if i'm wrong. This allow to do some sort of "retrieval" preprocessing and then using the retrieval with the curated results anywhere you could use a retriever. My use case is to generate diff indexes with diff embeddings and sources for a more colorful results then filtering them with one or many document formatters. I saw some people looking for something like this, here: https://github.com/hwchase17/langchain/issues/3991 and something similar here: https://github.com/hwchase17/langchain/issues/5555 This is just a proposal I know I'm missing tests , etc. If you think this is a worth it idea I can work on tests and anything you want to change.

Lance Martin	4092fd21dc	YoutubeAudioLoader and updates to OpenAIWhisperParser (#5772 ) This introduces the `YoutubeAudioLoader`, which will load blobs from a YouTube url and write them. Blobs are then parsed by `OpenAIWhisperParser()`, as show in this [PR](https://github.com/hwchase17/langchain/pull/5580), but we extend the parser to split audio such that each chuck meets the 25MB OpenAI size limit. As shown in the notebook, this enables a very simple UX: ``` # Transcribe the video to text loader = GenericLoader(YoutubeAudioLoader([url],save_dir),OpenAIWhisperParser()) docs = loader.load() ``` Tested on full set of Karpathy lecture videos: ``` # Karpathy lecture videos urls = ["https://youtu.be/VMj-3S1tku0" "https://youtu.be/PaCmpygFfXo", "https://youtu.be/TCH_1BHY58I", "https://youtu.be/P6sfmUTpUmc", "https://youtu.be/q8SA3rM6ckI", "https://youtu.be/t3YJ5hKiMQ0", "https://youtu.be/kCc8FmEb1nY"] # Directory to save audio files save_dir = "~/Downloads/YouTube" # Transcribe the videos to text loader = GenericLoader(YoutubeAudioLoader(urls,save_dir),OpenAIWhisperParser()) docs = loader.load() ```	1 year ago

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. Added a test for the integration: https://github.com/haoch/langchain/blob/clickhouse/tests/integration_tests/vectorstores/test_clickhouse.py 2.

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

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?

Waldecir Santos	db45970a66	Fix SQLAlchemy truncating text when it is too big (#5206 ) # Fixes SQLAlchemy truncating the result if you have a big/text column with many chars. SQLAlchemy truncates columns if you try to convert a Row or Sequence to a string directly For comparison: - Before: ```[('Harrison', 'That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio ... (2 characters truncated) ... hat is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio ')]``` - After: ```[('Harrison', 'That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio That is my Bio ')]``` ## Who can review? Community members can review the PR once tests pass. Tag maintainers/contributors who might be interested: I'm not sure who to tag for chains, maybe @vowelparrot ?	1 year ago
