ykerus	b697bbb5b5	Remove backticks without clear purpose from docs (#6442 ) #### Description - Removed two backticks surrounding the phrase "chat messages as" - This phrase stood out among other formatted words/phrases such as `prompt`, `role`, `PromptTemplate`, etc., which all seem to have a clear function. - `chat messages as`, formatted as such, confused me while reading, leading me to believe the backticks were misplaced. #### Who can review? @hwchase17 <!-- For a quicker response, figure out the right person to tag with @ @hwchase17 - project lead Tracing / Callbacks - @agola11 Async - @agola11 DataLoaders - @eyurtsev Models - @hwchase17 - @agola11 Agents / Tools / Toolkits - @hwchase17 VectorStores / Retrievers / Memory - @dev2049 -->	1 year ago

Saba Sturua	427551eabf	DocArray as a Retriever (#6031 ) ## DocArray as a Retriever [DocArray](https://github.com/docarray/docarray) is an open-source tool for managing your multi-modal data. It offers flexibility to store and search through your data using various document index backends. This PR introduces `DocArrayRetriever` - which works with any available backend and serves as a retriever for Langchain apps. Also, I added 2 notebooks: DocArray Backends - intro to all 5 currently supported backends, how to initialize, index, and use them as a retriever DocArray Usage - showcasing what additional search parameters you can pass to create versatile retrievers Example: ```python from docarray.index import InMemoryExactNNIndex from docarray import BaseDoc, DocList from docarray.typing import NdArray from langchain.embeddings.openai import OpenAIEmbeddings from langchain.retrievers import DocArrayRetriever # define document schema class MyDoc(BaseDoc): description: str description_embedding: NdArray[1536] embeddings = OpenAIEmbeddings() # create documents descriptions = ["description 1", "description 2"] desc_embeddings = embeddings.embed_documents(texts=descriptions) docs = DocList[MyDoc]( [ MyDoc(description=desc, description_embedding=embedding) for desc, embedding in zip(descriptions, desc_embeddings) ] ) # initialize document index with data db = InMemoryExactNNIndex[MyDoc](docs) # create a retriever retriever = DocArrayRetriever( index=db, embeddings=embeddings, search_field="description_embedding", content_field="description", ) # find the relevant document doc = retriever.get_relevant_documents("action movies") print(doc) ``` #### Who can review? @dev2049 --------- Signed-off-by: jupyterjazz <saba.sturua@jina.ai>	1 year ago

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

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

Initially, the `MaxMarginalRelevanceExampleSelector` class is used as an `example_selector` argument to the `FewShotPromptTemplate` class. Then, according to the text, a comparison is made to regular similarity search. However, the `FewShotPromptTemplate` still uses the `MaxMarginalRelevanceExampleSelector` class, so the output is the same. To fix it, I added an instantiation of the `SemanticSimilarityExampleSelector` class, because this seems to be what is intended. ## Who can review? @hwchase17	1 year ago

I'm adding the missing integrations in a consistent format: 1. description of the integrated system 2. `Installation and Setup` section with 'pip install ...`, Key setup, and other necessary settings 3. Sections like `LLM`, `Text Embedding Models`, `Chat Models`... with links to correspondent examples and imports of the used classes. This PR keeps new docs, that are presented in the `docs/modules/models/text_embedding/examples` but missed in the `ecosystem/integrations`. The next PRs will cover the next example sections. Also updated `integrations.rst`: added the `Dependencies` section with a link to the packages used in LangChain. ## Who can review? @hwchase17 @eyurtsev @dev2049	1 year ago

Martin Holecek	44b48d9518	Fix update_document function, add test and documentation. (#5359 ) # Fix for `update_document` Function in Chroma ## Summary This pull request addresses an issue with the `update_document` function in the Chroma class, as described in [#5031](https://github.com/hwchase17/langchain/issues/5031#issuecomment-1562577947). The issue was identified as an `AttributeError` raised when calling `update_document` due to a missing corresponding method in the `Collection` object. This fix refactors the `update_document` method in `Chroma` to correctly interact with the `Collection` object. ## Changes 1. Fixed the `update_document` method in the `Chroma` class to correctly call methods on the `Collection` object. 2. Added the corresponding test `test_chroma_update_document` in `tests/integration_tests/vectorstores/test_chroma.py` to reflect the updated method call. 3. Added an example and explanation of how to use the `update_document` function in the Jupyter notebook tutorial for Chroma. ## Test Plan All existing tests pass after this change. In addition, the `test_chroma_update_document` test case now correctly checks the functionality of `update_document`, ensuring that the function works as expected and updates the content of documents correctly. ## Reviewers @dev2049 This fix will ensure that users are able to use the `update_document` function as expected, without encountering the previous `AttributeError`. This will enhance the usability and reliability of the Chroma class for all users. Thank you for considering this pull request. I look forward to your feedback and suggestions.	1 year ago
Janos Tolgyesi	5f4552391f	Add SKLearnVectorStore (#5305 ) # Add SKLearnVectorStore This PR adds SKLearnVectorStore, a simply vector store based on NearestNeighbors implementations in the scikit-learn package. This provides a simple drop-in vector store implementation with minimal dependencies (scikit-learn is typically installed in a data scientist / ml engineer environment). The vector store can be persisted and loaded from json, bson and parquet format. SKLearnVectorStore has soft (dynamic) dependency on the scikit-learn, numpy and pandas packages. Persisting to bson requires the bson package, persisting to parquet requires the pyarrow package. ## Before submitting Integration tests are provided under `tests/integration_tests/vectorstores/test_sklearn.py` Sample usage notebook is provided under `docs/modules/indexes/vectorstores/examples/sklear.ipynb` Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago

In the previous version, there was setup common to all examples but under the `In Memory Caching` heading. If a user comes and only wants to try a particular example, they will run the common setup, then the cells for the specific provider they are interested in. Then they will get import and variable reference errors. This commit moves the common setup to the top to avoid this. ## Who can review? Community members can review the PR once tests pass.

Davis Chase	3be9ba14f3	OpenSearch top k parameter fix (#5216 ) For most queries it's the `size` parameter that determines final number of documents to return. Since our abstractions refer to this as `k`, set this to be `k` everywhere instead of expecting a separate param. Would be great to have someone more familiar with OpenSearch validate that this is reasonable (e.g. that having `size` and what OpenSearch calls `k` be the same won't lead to any strange behavior). cc @naveentatikonda Closes #5212	1 year ago
