R2R Local System Installation

This guide will walk you through installing and running R2R on your local system without using Docker. This method allows for more customization and control over individual components.

​
Prerequisites

Before starting, ensure you have the following installed and/or available in the cloud:
  • Python 3.10 or higher
  • pip (Python package manager)
  • Git
  • Postgres + pgvector

​
Install the R2R CLI and extra dependencies

First, install the R2R CLI with the additional light dependencies: 
pip install 'r2r[core,ingestion-bundle]'
The core and ingestion-bundle dependencies, combined with a Postgres database, provide the necessary components to deploy a user-facing R2R application into production. If you need advanced features like orchestration or parsing with Unstructured.io then refer to the full installation .

​
Environment Setup

R2R requires connections to various services. Set up the following environment variables based on your needs:
Note, cloud providers are optional as R2R can be run entirely locally.
 # Set cloud LLM settings
 export OPENAI_API_KEY=sk-...
 # export ANTHROPIC_API_KEY=...
 # ...
With R2R you can connect to your own instance of Postgres+pgvector or a remote cloud instance.
 # Set Postgres+pgvector settings
 export POSTGRES_USER=$YOUR_POSTGRES_USER
 export POSTGRES_PASSWORD=$YOUR_POSTGRES_PASSWORD
 export POSTGRES_HOST=$YOUR_POSTGRES_HOST
 export POSTGRES_PORT=$YOUR_POSTGRES_PORT
 export POSTGRES_DBNAME=$YOUR_POSTGRES_DBNAME
 export R2R_PROJECT_NAME=$YOUR_PROJECT_NAME # see note below
The R2R_PROJECT_NAME environment variable defines the tables within your Postgres database where the selected R2R project resides. If the required tables for R2R do not exist then they will be created by R2R during initialization.
If you are unfamiliar with Postgres then Supabase’s free cloud offering is a good place to start.

​
Running R2R

After setting up your environment, you can start R2R using the following command: 
r2r serve
For local LLM usage: 
r2r serve --config-name=local_llm

​
Python Development Mode

For those looking to develop R2R locally:
  1. Install Poetry: Follow instructions on the official Poetry website.
  2. Clone and install dependencies: 
    git clone git@github.com:SciPhi-AI/R2R.git
cd R2R/py
poetry install -E "core ingestion-bundle"
  3. Setup environment: Follow the steps listed in the Environment Setup section above. Additionally, you may introduce a local .env file to make development easier, and you can customize your local r2r.toml to suit your specific needs.
  4. Start your server: 
poetry run r2r serve

​
