This release is a pre-release and may not be stable for production use.
fastscipy
Faster SciPy calls. The same results, byte for byte.
Rust kernels and shared thread pools accelerate supported calls. Everything else stays with SciPy.
import fastscipy
fastscipy.patch()
from scipy import ndimage
clean = ndimage.median_filter(image, size=3)
Run on a MacBook Pro with M5 Pro.
Install
pip install --pre fastscipy
Prebuilt wheels; no Rust required.
Experimental: macOS 14+ Apple Silicon · SciPy 1.18 · Python 3.12–3.14. Unsupported platforms and versions stay unpatched.
Call patch() before importing libraries that use SciPy.
Use patch(threads=4) to choose a thread budget, status() to see what's enabled,
and unpatch() to restore SciPy.
Performance
Geometric-mean speedups over unpatched SciPy, measured on an Apple M5 Pro.
