i am already check the six and joblib these modules satisfied the requirement

[amueller]

This is not an error, it's a warning, and can be safely ignored.

[filipjakubowski]

It is not warning anymore.

Repos like scikit-learn depreciated six: https://github.com/scikit-learn/scikit-learn/pull/12916/files

[amueller]

True, it was removed in the last release. I'll fix it!

[filipjakubowski]

plot_interactive_tree.py

from sklearn.externals.six import StringIO -> from io import StringIO

I made it work in my repo fork.

[amueller]

Pushed a fix here and to the notebook repo and to pipy. please let me know if it works.

[gcaldiera]

Similar error. Not sure if they are connected:

[amueller]

@gcaldiera thanks for reporting. I'm not sure why I didn't see that when I ran everything yesterday but it's definitely related. I'll look into it!

[amueller]

A work-around is changing the line to "from joblib import Memory"

[amueller]

Thanks, can you try upgrading mglearn with pip and see if the error persists?

[gcaldiera]

No error now. Just a warning (see below) but it doesn't seem to be a problem. Thanks.

Thanks for reporting, not an issue for now, though :)

seems to be an issue now?

ImportError: 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()

for the California housing dataset and::

from sklearn.datasets import fetch_openml
housing = fetch_openml(name="house_prices", as_frame=True)

for the Ames housing dataset.

[Mentoni]

I'm getting the same error message while trying to import dataset from mglearn. Please reply and help fix it. How does load_boston related to other data set in mglearn? What is the solution

[amueller]

You should be able to upload from pypi now and the error should go away. however, the book has been written with a much older version of scikit-learn, and using the current version might break some of the examples. Really, the book needs to be revised for the current version to work properly with it.
