pylibkriging — Python binding for libKriging
libKriging is a C++ library for Kriging / Gaussian process
regression (fit, predict, simulate, update, input warpings, and scalable variants for large designs).
pylibkriging exposes it to Python through pybind11.
Installation
pip3 install pylibkriging
Requires Python ≥ 3.7 and NumPy (≥ 1.18, NumPy 2 is supported). Pre-built wheels are published for the usual Linux / macOS / Windows targets; see the releases page for the other packages.
Example
X is an n × d float64 array (one row per observation) and y a length-n vector.
import numpy as np
import pylibkriging as lk
X = np.array([[0.0], [0.25], [0.5], [0.75], [1.0]])
f = lambda x: 1 - 0.5 * (np.sin(12 * x) / (1 + x) + 2 * np.cos(7 * x) * x ** 5 + 0.7)
y = f(X[:, 0])
model = lk.Kriging(y, X, "matern5_2")
print(model.summary())
x = np.linspace(0, 1, 100).reshape(-1, 1)
mean, stdev, cov, mean_deriv, stdev_deriv = model.predict(x, return_stdev=True)
sims = model.simulate(nsim=10, seed=123, X=x) # shape (100, 10)
Other classes: WarpKriging (input warpings, categorical / ordinal inputs), MLPKriging, NestedKriging (large
designs), and scikit-learn compatible estimators in pylibkriging.sklearn (pip3 install pylibkriging[sklearn]). See the
method reference for all bindings and the
main README for more examples.
Building from source
Requires a C++17 compiler, CMake ≥ 3.13 and a BLAS/LAPACK implementation. From the repository root (cloned with
--recurse-submodules):
ENABLE_PYTHON_BINDING=on tools/linux-macos/install.sh
ENABLE_PYTHON_BINDING=on tools/linux-macos/build.sh
ENABLE_PYTHON_BINDING=on tools/linux-macos/test.sh
or python3 -m pip install . from the repository root to build and install the wheel directly. See
bindings/Python/README.md for the Windows commands and the other options.
To use a rebuilt module in a running interpreter:
import importlib
import pylibkriging as lk
importlib.reload(lk)
Releasing
Wheels are built and uploaded to PyPI by the release-python GitHub workflow
(.github/workflows/release-python.yml, which calls tools/release/python-release.sh) when a release tag is pushed.
