Shared types and utilities for evalaution

Coral

A PyTorch-based neural network library for board game evaluation.

Overview

Coral provides a flexible framework for building and deploying neural networks to evaluate board game positions. It includes modular components for input conversion, neural network architectures, and output interpretation.

Features

• Multiple NN Architectures: Multi-layer perceptrons, transformers, and custom models
• Flexible Input/Output Conversion: Modular converters for different board representations and evaluation formats
• Point-of-View Evaluation: Support for evaluating positions from different player perspectives
• PyTorch Integration: Built on PyTorch with JIT compilation support for optimized inference

Installation

pip install git+https://github.com/victorgabillon/coral.git@main

Requirements

• Python >= 3.13
• PyTorch
• valanga (board game library)
