Following this tutoral about using OpenAI Embeddings with FAISS https://python.langchain.com/docs/integrations/vectorstores/faiss ```python from langchain.embeddings.openai import OpenAIEmbeddings from langchain.text_splitter import CharacterTextSplitter from langchain.vectorstores import FAISS from langchain.document_loaders import TextLoader from langchain.document_loaders import TextLoader loader = TextLoader("../../../extras/modules/state_of_the_union.txt") documents = loader.load() text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0) docs = text_splitter.split_documents(documents) embeddings = OpenAIEmbeddings() ``` This works fine ```python db = FAISS.from_documents(docs, embeddings) query = "What did the president say about Ketanji Brown Jackson" docs = db.similarity_search(query) ``` But the async version is not ```python db = await FAISS.afrom_documents(docs, embeddings) # NotImplementedError query = "What did the president say about Ketanji Brown Jackson" docs = await db.asimilarity_search(query) # this will use await asyncio.get_event_loop().run_in_executor under the hood and will not call OpenAIEmbeddings.aembed_query but call OpenAIEmbeddings.embed_query ``` So this PR add async/await supports for FAISS --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>
Website
This website is built using Docusaurus 2, a modern static website generator.
Installation
$ yarn
Local Development
$ yarn start
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
Build
$ yarn build
This command generates static content into the build directory and can be served using any static contents hosting service.
Deployment
Using SSH:
$ USE_SSH=true yarn deploy
Not using SSH:
$ GIT_USER=<Your GitHub username> yarn deploy
If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
Continuous Integration
Some common defaults for linting/formatting have been set for you. If you integrate your project with an open-source Continuous Integration system (e.g. Travis CI, CircleCI), you may check for issues using the following command.
$ yarn ci
