The detailed walkthrough of the Weaviate wrapper was pointing to the getting-started notebook. Fixed it to point to the Weaviable notebook in the examples folder.

Weaviate
This page covers how to use the Weaviate ecosystem within LangChain.
What is Weaviate?
Weaviate in a nutshell:
- Weaviate is an open-source database of the type vector search engine.
- Weaviate allows you to store JSON documents in a class property-like fashion while attaching machine learning vectors to these documents to represent them in vector space.
- Weaviate can be used stand-alone (aka bring your vectors) or with a variety of modules that can do the vectorization for you and extend the core capabilities.
- Weaviate has a GraphQL-API to access your data easily.
- We aim to bring your vector search set up to production to query in mere milliseconds (check our open source benchmarks to see if Weaviate fits your use case).
- Get to know Weaviate in the basics getting started guide in under five minutes.
Weaviate in detail:
Weaviate is a low-latency vector search engine with out-of-the-box support for different media types (text, images, etc.). It offers Semantic Search, Question-Answer Extraction, Classification, Customizable Models (PyTorch/TensorFlow/Keras), etc. Built from scratch in Go, Weaviate stores both objects and vectors, allowing for combining vector search with structured filtering and the fault tolerance of a cloud-native database. It is all accessible through GraphQL, REST, and various client-side programming languages.
Installation and Setup
- Install the Python SDK with
pip install weaviate-client
Wrappers
VectorStore
There exists a wrapper around Weaviate indexes, allowing you to use it as a vectorstore, whether for semantic search or example selection.
To import this vectorstore:
from langchain.vectorstores import Weaviate
