rl-llm-toolkit 0.2.0

Open-source framework for Reinforcement Learning integrated with Large Language Models

RL-LLM Toolkit

Democratizing Reinforcement Learning with Large Language Models

🚀 Overview

RL-LLM Toolkit is an open-source framework that integrates Reinforcement Learning with Large Language Models to create intelligent agents accessible to beginners and researchers. By simulating human feedback via LLMs, we reduce RLHF costs by up to 50% while maintaining training quality.

Key Features

• 🎮 Gymnasium-Compatible Environments: Easy-to-use RL environments for games, finance, and robotics
• 🤖 LLM-Powered Rewards: Generate dense rewards using local or API-based LLMs
• 📊 State-of-the-Art Algorithms: PPO, DQN, and more with modular architecture
• 🔧 Plug-and-Play Design: Swap algorithms, environments, and LLMs effortlessly
• 📚 Educational Focus: Interactive Jupyter notebooks and comprehensive tutorials
• 🌐 Hugging Face Integration: Share models and datasets with the community

🎯 Quick Start

# Install the toolkit
pip install rl-llm-toolkit

# Run a simple example
python -m rl_llm_toolkit.examples.cartpole

📦 Installation

From PyPI (Coming Soon)

pip install rl-llm-toolkit

From Source

git clone https://github.com/tonipcv/hugo.git
cd hugo
pip install -e .

Optional Dependencies

# For LLM integration
pip install -e ".[llm]"

# For development
pip install -e ".[dev]"

# For all features
pip install -e ".[all]"

💡 Usage Example

from rl_llm_toolkit import RLEnvironment, PPOAgent, LLMRewardShaper
from rl_llm_toolkit.llm import OllamaBackend

# Create environment
env = RLEnvironment("CartPole-v1")

# Set up LLM-based reward shaping
llm = OllamaBackend(model="llama3")
reward_shaper = LLMRewardShaper(llm, prompt_template="custom_template")

# Train agent
agent = PPOAgent(env, reward_shaper=reward_shaper)
agent.train(total_timesteps=100000)

# Evaluate
agent.evaluate(episodes=10, render=True)
