Installation

Install from PyPI (recommended)

pip install quadsv

Or install with optional dependencies:

pip install quadsv[spatial]   # For AnnData/SpatialData support
pip install quadsv[dev]       # For development tools
pip install quadsv[docs]      # For building documentation

Development installation

Latest development version from GitHub: .. code-block:: bash

pip install git+https://github.com/JiayuSuPKU/EquivSVT.git#egg=quadsv

Alternatively, clone and install in editable mode:

git clone https://github.com/JiayuSuPKU/EquivSVT.git
cd EquivSVT
pip install -e ".[dev,spatial]"

Requirements

• Python: 3.10+ (3.14+ users: see note below)

• Core dependencies: numpy, scipy, scikit-learn, pandas, scanpy, joblib, tqdm

• Optional: anndata (PatternDetector), spatialdata (PatternDetectorFFT)

Note for Python 3.14+: Some third-party pytest plugins (napari, npe2) have pydantic v1 incompatibilities. Tests run via python -m unittest or with plugins disabled in pyproject.toml.
