- Parameters
- n_classint, default=10
The number of classes to return. Between 0 and 10.
- return_X_ybool, default=False
If True, returns
(data, target)instead of a Bunch object. See below for more information about thedataandtargetobject.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_yis True, then (data,target) will be pandas DataFrames or Series as described below.New in version 0.23.
- Returns
- data

- data{ndarray, dataframe} of shape (1797, 64)
The flattened data matrix. If
as_frame=True,datawill be a pandas DataFrame.- target: {ndarray, Series} of shape (1797,)
The classification target. If
as_frame=True,targetwill be a pandas Series.- feature_names: list
The names of the dataset columns.
- target_names: list

New in version 0.20.
- frame: DataFrame of shape (1797, 65)
Only present when
as_frame=True. DataFrame withdataandtarget.New in version 0.23.
- images: {ndarray} of shape (1797, 8, 8)
The raw image data.
- DESCR: str
The full description of the dataset.
- (data, target)tuple if

Examples
To load the data and visualize the images:
>>> from sklearn.datasets import load_digits >>> digits = load_digits() >>> print(digits.data.shape) (1797, 64) >>> import matplotlib.pyplot as plt >>> plt.gray() >>> plt.matshow(digits.images[0]) >>> plt.show()
