OpenSTARLab PhaseLearn Modeling package

Introduction

The OpenSTARLab PhaseLearn package is the fundamental library for modeling and analyzing play phases in sports. It provides a robust framework to train and perform inference on play phases using state-of-the-art spatio-temporal architectures.

Key Concepts

• Definition of Play Phase: The estimation targets are Phases of Play as defined by FIFA.
• This package supports data preprocessed by the OpenSTARLab PreProcessing package.

Installation

• Install pytorch (recommended version 2.4.0 linux pip python3.9 cuda11.8)

pip install torch torchvision torchaudio

• To install this package via PyPI

pip install openstarlab-phaselearn

• To install manually

git clone git@github.com:open-starlab/PhaseLearn.git
cd ./PhaseLearn
pip install -e .

Quick Start

Get started with inference using pre-trained models.

1. Download Pre-trained Model: Download the model weights from MODEL URL and place them in the model/ directory.

2. Generate Phase Data: Before estimating, you must convert the raw tracking into the Phase Data format.

   • PreProcessing Documentation

3. Run Inference: Perform phase estimation on your data.

   • Inference Example Guide

Training and Analysis from Scratch

Follow these steps to train your own play phase model using the SoccerTrack-v2 dataset.

1. Data Acquisition:

   • Tracking Data: Obtain the raw data from SoccerTrack-v2.
     • Required Files Guide (Note: Different files are required for Match IDs >= 130000 and < 130000).
   • Phase Annotation Data: Download the play phase annotation data from DATA URL and place them in the data/ directory.

2. Generate Phase Data: Before training, you must convert the raw tracking into the Phase Data format.

   • PreProcessing Documentation

3. Training & Evaluation: Once the data is prepared, you can execute the training pipeline.
