Chroma Data Store

Give your skill the ability to store and retrieve data from a Chroma database.

Running the Chroma Database

1. Clone this rep
2. Run yarn start.chroma.docker

Setting an embedding model

By default, the ChromaDabatase class will use llama3.2 hosted through Ollama to generate embeddings

Installing Ollama

1. Visit https://ollama.com
2. Click "Download"
3. Select your OS

Installing Llama3.2

Llama 3.2 is the newest version of Llama (as of this writing) that supports embeddings.

1. Inside of terminal, run ollama run llama3.2
2. You should be able to visit http://localhost:11434/api/embeddings and get a 405 response (this is because the route only accepts POST requests)

Improving embeddings with nomic-embed-text

We have seen significantly better search performance when using nomic-embed-text to generate embeddings.

Run ollama pull nomic-embed-text

Using in your skill

Add the following to your env:

DB_CONNECTION_STRING="chromadb://localhost:8000"
DB_ADAPTER="@sprucelabs/chroma-data-store"
