Pyligent

Pyligent is a framework for reinforcement learning through search-based reasoning, implementing concepts from From Reasoning to Super-Intelligence: A Search-Theoretic Perspective.

Installation

Note: Pyligent requires PyTorch. Please install the version appropriate for your hardware before installing Pyligent.

1. Install PyTorch

Using uv:

Check the official guide

For CPU-only environments:

pip install torch --index-url https://download.pytorch.org/whl/cpu
