Pupil-LIMlab 1.1

A pupil analysis and inference toolkit

PupilToolKit

A lightweight toolkit for pupil tracking and processing used by LIM Lab.

Overview

PupilToolKit provides utilities and pipelines for pupil extraction, processing, and inference. The repository includes two main components:

• PupilProcessing: processing pipelines and utility functions.
• PupilSense: integration with PupilSense inference tools and example scripts.

Example configuration files for experiments and devices are stored in the configs/ directory.

Features

• Extract and process pupil data
• Run inference with PupilSense models
• Example scripts and test coverage

Requirements

• Python 3.10+ (recommended)
• Typical scientific packages: numpy, scipy, etc. (see pyproject.toml / setup.py)

Create and activate a virtual environment before installing:

conda create -n process_pupil python=3.10 -y
conda activate process_pupil
pip install -e .

Or using pip/venv:

python -m venv .venv
.venv\\Scripts\\activate
pip install -e .

Installation

Recommended: create and activate a virtual environment (conda or venv) before installing packages.

• PyTorch & TorchVision (CUDA 12.1) — install the CUDA 12.1 builds of PyTorch 2.2 and TorchVision 0.17.0:

pip install torch==2.2.0+cu121 torchvision==0.17.0+cu121 -f https://download.pytorch.org/whl/torch_stable.html

If you do not have CUDA 12.1 or need a CPU-only build, install the matching CPU/compatible wheel instead (omit +cu121 or follow the official PyTorch install selector at https://pytorch.org).

• Detectron2 — platform-specific instructions:

• Windows (pre-built wheels):

pip install detectron2 --extra-index-url https://myhloli.github.io/wheels/

• Linux (install from upstream):

pip install --no-build-isolation git+https://github.com/facebookresearch/detectron2.git

• PupilLIMlab package — install the project package from PyPI (or your registry):

pip install PupilLIMlabSWC

After these steps you should be able to run the example scripts and the PupilSense inference tools.

Quick start

Run the example script:

python example/run_script.py

Run tests:

pytest -q
