Chroma

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

Wrappers

VectorStore

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
