Scikit-Garden or skgarden (pronounced as skarden) is a garden for Scikit-Learn compatible decision trees and forests.

Weights at different depths of a MondrianTree

Ordered prediction intervals on the Boston dataset.


Scikit-Garden depends on NumPy, SciPy, Scikit-Learn and Cython. So make sure these dependencies are installed using pip:

pip3 install setuptools numpy scipy scikit-learn cython

After that Scikit-Garden can be installed using pip.

pip install scikit-garden

Available models


  • MondrianForestRegressor
  • ExtraTreesRegressor (with return_std support)
  • ExtraTreesQuantileRegressor
  • RandomForestRegressor (with return_std support)
  • RandomForestQuantileRegressor


  • MondrianForestClassifier


The estimators in Scikit-Garden are Scikit-Learn compatible and can serve as a drop-in replacement for Scikit-Learn's trees and forests.

from sklearn.datasets import load_boston
X, y = load_boston()

### Use MondrianForests for variance estimation
from skgarden import MondrianForestRegressor
mfr = MondrianForestRegressor(), y)
y_mean, y_std = mfr.predict(X, return_std=True)

### Use QuantileForests for quantile estimation
from skgarden import RandomForestQuantileRegressor
rfqr = RandomForestQuantileRegressor(random_state=0), y)
y_mean = rfqr.predict(X)
y_median = rfqr.predict(X, 50)
