lonestriker	6f36f0f930	Add oobabooga/text-generation-webui support as a llm (#5997 ) Add oobabooga/text-generation-webui support as an LLM. Currently, supports using text-generation-webui's non-streaming API interface. Allows users who already have text-gen running to use the same models with langchain. #### Before submitting Simple usage, similar to existing LLM supported: ``` from langchain.llms import TextGen llm = TextGen(model_url = "http://localhost:5000") ``` #### Who can review? @hwchase17 - project lead --------- Co-authored-by: Hien Ngo <Hien.Ngo@adia.ae>	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.
