# gstools-cython — Cython backend for GSTools.

License: copyleft · Maintenance: aging · Downloads: 130.8K/mo

## What it is and what it does

gstools-cython is a compiled backend component containing Cython-optimized implementations of core spatial statistical algorithms. It is not intended for direct installation but is pulled in as a dependency by its parent package. The package depends only on numpy and supports Python 3.10 through 3.14 across Linux, macOS, and Windows platforms.

Pre-built wheels are available for common architectures (x86_64, ARM64, and others), so installation typically requires no compilation on the user's end. Because it functions as a backend component, interaction occurs indirectly through the parent package's public API rather than through direct imports.

Use it for:

- Accelerating spatial statistical computations in geostatistical workflows.
- Speeding up numerical operations in large-scale spatial modeling.
- Enabling faster simulations in hydrology and hydrogeology applications.
- Improving performance of covariance and interpolation calculations.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides optimized Cython implementations of geostatistical algorithms, accelerating spatial statistical computations for the parent package.

Yes, as a dependency of its parent package. If you are using the parent package for geostatistical modeling, gstools-cython will be pulled in automatically and will transparently accelerate computations. The package is stable with no known vulnerabilities and supports current Python versions. The aging maintenance status (231 days since last release) is not a blocker for a stable backend component.

## Install

pip install gstools-cython
uv add gstools-cython
poetry add gstools-cython

## Installing gstools-cython

Before you install: Medium install friction due to compiled wheels across multiple platforms and Python versions (3.10–3.14). Last release was 231 days ago; maintenance status is aging but the repository remains active and marked Production/Stable.

License in practice: Licensed under LGPL-3.0-or-later (copyleft). Derivative works and modifications must be distributed under compatible terms; proprietary use requires careful license review.

Quickstart:

# gstools-cython is installed as a backend dependency
pip install gstools-cython
import numpy
# Backend is used transparently by parent package

Requires numpy >= 1.20.0 and Python >= 3.10. This package is not meant to be installed directly but as a backend component.

Verify before relying:

- Specific performance improvements or benchmarks compared to non-Cython implementations.
- Whether this package is automatically selected or requires explicit configuration when used.
- Direct usage patterns and API surface beyond backend acceleration role.
