`load_boston` has been removed from scikit-learn since version 1.2.

|

The Boston housing prices dataset has an ethical problem: as
|
||||
investigated in [1], the authors of this dataset engineered a
|
||||
non-invertible variable "B" assuming that racial self-segregation had a
|
||||
positive impact on house prices [2]. Furthermore the goal of the
|
||||
research that led to the creation of this dataset was to study the
|
||||
impact of air quality but it did not give adequate demonstration of the
|
||||
validity of this assumption.
|
||||
|
||||
The scikit-learn maintainers therefore strongly discourage the use of
|
||||
this dataset unless the purpose of the code is to study and educate
|
||||
about ethical issues in data science and machine learning.
|
||||
|
||||
In this special case, you can fetch the dataset from the original
|
||||
source::
|

import pandas as pd
|
||||
import numpy as np
|
||||
|
||||
data_url = "http://lib.stat.cmu.edu/datasets/boston"
|

raw_df = pd.read_csv(data_url, sep="\s+", skiprows=22, header=None)
|
||||
data = np.hstack([raw_df.values[::2, :], raw_df.values[1::2, :2]])
|
||||
target = raw_df.values[1::2, 2]
|
||||
|
||||
Alternative datasets include the California housing dataset and the
|
||||
Ames housing dataset. You can load the datasets as follows::

from sklearn.datasets import fetch_california_housing
|

housing = fetch_california_housing()

investigated in [1], the authors of this dataset engineered a
