Quick Start

Installation

Pre-built binaries are available for Windows, macOS, and Linux:

# Python (PyPI) - uv preferred over pip
uv add pymomentum-cpu           # CPU version
uv add pymomentum-gpu           # GPU version with CUDA
pip install pymomentum-cpu      # Alternative: using pip
pip install pymomentum-gpu

# Python (Conda/Pixi)
pixi add pymomentum             # Auto-detects GPU/CPU
conda install -c conda-forge pymomentum

# C++ (Conda/Pixi only)
pixi add momentum-cpp
conda install -c conda-forge momentum-cpp

📦 Browse packages: PyPI • conda-forge • prefix.dev

Quick Example

# Install and run
pip install pymomentum-cpu
python -c "import pymomentum.geometry as geom; print(dir(geom))"
