This page covers how to use the Chroma ecosystem within LangChain. It is broken into two parts: installation and setup, and then references to specific Chroma wrappers.
Installation and Setup#
Install the Python package with
pip install chromadb
There exists a wrapper around Chroma vector databases, allowing you to use it as a vectorstore, whether for semantic search or example selection.
To import this vectorstore:
from langchain.vectorstores import Chroma
For a more detailed walkthrough of the Chroma wrapper, see this notebook
