Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

What things you need to install the software and how to install them.

• Python 3.10 or higher
• Pip
• Virtualenv
• Supabase account
• Supabase API key
• Supabase URL

Installing

• Clone the repository

git clone git@github.com:StanGirard/quiver.git & cd quiver

• Create a virtual environment

virtualenv venv

• Activate the virtual environment

source venv/bin/activate

• Install the dependencies

pip install -r requirements.txt

• Copy the streamlit secrets.toml example file

cp .streamlit/secrets.toml.example .streamlit/secrets.toml

• Add your credentials to .streamlit/secrets.toml file

supabase_url = "SUPABASE_URL"
supabase_service_key = "SUPABASE_SERVICE_KEY"
openai_api_key = "OPENAI_API_KEY"

• Run the migration script on the Supabase database via the web interface

-- Enable the pgvector extension to work with embedding vectors
       create extension vector;

       -- Create a table to store your documents
       create table documents (
       id bigserial primary key,
       content text, -- corresponds to Document.pageContent
       metadata jsonb, -- corresponds to Document.metadata
       embedding vector(1536) -- 1536 works for OpenAI embeddings, change if needed
       );

       CREATE FUNCTION match_documents(query_embedding vector(1536), match_count int)
           RETURNS TABLE(
               id bigint,
               content text,
               metadata jsonb,
               -- we return matched vectors to enable maximal marginal relevance searches
               embedding vector(1536),
               similarity float)
           LANGUAGE plpgsql
           AS $$
           # variable_conflict use_column
       BEGIN
           RETURN query
           SELECT
               id,
               content,
               metadata,
               embedding,
               1 -(documents.embedding <=> query_embedding) AS similarity
           FROM
               documents
           ORDER BY
               documents.embedding <=> query_embedding
           LIMIT match_count;
       END;
       $$;
