sklearn.datasets.load_diabetes¶

sklearn.datasets.load_diabetes(*, return_X_y=False, as_frame=False)[source]¶

Load and return the diabetes dataset (regression).

Samples total	442
Dimensionality	10
Features	real, -.2 < x < .2
Targets	integer 25 - 346

Note

The meaning of each feature (i.e. feature_names) might be unclear (especially for ltg) as the documentation of the original dataset is not explicit. We provide information that seems correct in regard with the scientific literature in this field of research.

Read more in the User Guide.

Parameters

return_X_ybool, default=False.

If True, returns (data, target) instead of a Bunch object. See below for more information about the data and target object.

New in version 0.18.

as_framebool, default=False

If True, the data is a pandas DataFrame including columns with appropriate dtypes (numeric). The target is a pandas DataFrame or Series depending on the number of target columns. If return_X_y is True, then (data, target) will be pandas DataFrames or Series as described below.

New in version 0.23.

Returns

dataBunch

Dictionary-like object, with the following attributes.

data{ndarray, dataframe} of shape (442, 10)

The data matrix. If as_frame=True, data will be a pandas DataFrame.

target: {ndarray, Series} of shape (442,)

The regression target. If as_frame=True, target will be a pandas Series.

feature_names: list

The names of the dataset columns.

frame: DataFrame of shape (442, 11)

Only present when as_frame=True. DataFrame with data and target.

New in version 0.23.

DESCR: str

The full description of the dataset.

data_filename: str

The path to the location of the data.

target_filename: str

The path to the location of the target.

(data, target)tuple if return_X_y is True

New in version 0.18.
