SLEAP is an open source deep-learning based framework for multi-animal pose tracking (Pereira et al., Nature Methods, 2022). It can be used to track any type or number of animals and includes an advanced labeling/training GUI for active learning and proofreading.

• Easy, one-line installation with support for all OSes
• Purpose-built GUI and human-in-the-loop workflow for rapidly labeling large datasets
• Single- and multi-animal pose estimation with top-down and bottom-up training strategies
• State-of-the-art pretrained and customizable neural network architectures that deliver accurate predictions with very few labels
• Fast training: 15 to 60 mins on a single GPU for a typical dataset
• Fast inference: up to 600+ FPS for batch, <10ms latency for realtime
• Support for remote training/inference workflow (for using SLEAP without GPUs)
• Flexible developer API for building integrated apps and customization

SLEAP is installed as a Python package. We strongly recommend using Miniconda to install SLEAP in its own environment.

You can find the latest version of SLEAP in the Releases page.

conda (Windows/Linux/GPU):

conda create -y -n sleap -c conda-forge -c nvidia -c sleap/label/dev -c sleap -c anaconda sleap

pip (any OS except Apple silicon):

pip install sleap[pypi]

See the docs for full installation instructions.
