Social LEAP Estimates Animal Poses (SLEAP)

SLEAP Demo

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.

Features

  • 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
  • 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
  • Two independent backends— sleap-nn and sleap-io for training/inference pipelines & handling SLEAP files respectively

Get some SLEAP

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

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

Quick install

Python 3.14 is not yet supported

SLEAP currently supports Python 3.11, 3.12, and 3.13.
Python 3.14 is not yet tested or supported.
By default, uv will use your system-installed Python.
If you have Python 3.14 installed, you must specify the Python version (≤3.13) in the install command.

For example:

uv tool install --python 3.13 "sleap[nn]"  ...

Replace ... with the rest of your install command as needed.

uv tool install (any OS):

First, install uv if you haven't already:

# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Then install SLEAP:

# Windows/Linux CUDA 12.8
uv tool install "sleap[nn]" --index https://download.pytorch.org/whl/cu128 --index https://pypi.org/simple

# macOS / CPU-only
uv tool install "sleap[nn]" --index https://download.pytorch.org/whl/cpu --index https://pypi.org/simple

Run the SLEAP GUI after installation:

sleap

See the docs for full installation instructions.
