sklearn.ensemble.partial_dependence.plot_partial_dependence(gbrt, X, features, feature_names=None, label=None, n_cols=3, grid_resolution=100, percentiles=(0.05, 0.95), n_jobs=None, verbose=0, ax=None, line_kw=None, contour_kw=None, **fig_kw)[source]

DEPRECATED: The function ensemble.plot_partial_dependence has been deprecated in favour of sklearn.inspection.plot_partial_dependence in 0.21 and will be removed in 0.23.

Partial dependence plots for features.

The len(features) plots are arranged in a grid with n_cols columns. Two-way partial dependence plots are plotted as contour plots.

Deprecated since version 0.21: This function was deprecated in version 0.21 in favor of sklearn.inspection.plot_partial_dependence and will be removed in 0.23.

gbrt : BaseGradientBoosting

A fitted gradient boosting model.

X : array-like, shape=(n_samples, n_features)

The data on which gbrt was trained.

features : seq of ints, strings, or tuples of ints or strings

If seq[i] is an int or a tuple with one int value, a one-way PDP is created; if seq[i] is a tuple of two ints, a two-way PDP is created. If feature_names is specified and seq[i] is an int, seq[i] must be < len(feature_names). If seq[i] is a string, feature_names must be specified, and seq[i] must be in feature_names.

feature_names : seq of str

Name of each feature; feature_names[i] holds the name of the feature with index i.

label : object

The class label for which the PDPs should be computed. Only if gbrt is a multi-class model. Must be in gbrt.classes_.

n_cols : int

The number of columns in the grid plot (default: 3).

grid_resolution : int, default=100

The number of equally spaced points on the axes.

percentiles : (low, high), default=(0.05, 0.95)

The lower and upper percentile used to create the extreme values for the PDP axes.

n_jobs : int or None, optional (default=None)

None means 1 unless in a joblib.parallel_backend context. -1 means using all processors. See Glossary for more details.

verbose : int

Verbose output during PD computations. Defaults to 0.

ax : Matplotlib axis object, default None

An axis object onto which the plots will be drawn.

line_kw : dict

Dict with keywords passed to the matplotlib.pyplot.plot call. For one-way partial dependence plots.

contour_kw : dict

Dict with keywords passed to the matplotlib.pyplot.plot call. For two-way partial dependence plots.

**fig_kw : dict

Dict with keywords passed to the figure() call. Note that all keywords not recognized above will be automatically included here.

fig : figure

The Matplotlib Figure object.

axs : seq of Axis objects

A seq of Axis objects, one for each subplot.
