[python-package] [tests] FutureWarning: load_boston will be removed in scikit-learn 1.2.

[TremaMiguel]

Description

Scikit-learn load_boston function will be removed in future version.

FutureWarning: Function load_boston is deprecated; `load_boston` is deprecated in 1.0 and will be removed in 1.2.

python-package tests test_engine.py, test_plotting.py, and test_sklearn.py uses boston dataset. Some of this tests have already been changed in #4895

Solution

Tests should be changed to another available regression dataset like load_diabetes or use proposed synthetic regression dataset.

[TremaMiguel]

I'm open to develop this once there is an agreement on which dataset to use.

@TremaMiguel Thanks a lot for bringing this to our attention! But we have already created an issue for this problem: #4793. Please let's continue discussion there.

it's just a version issue ,just don't bother

[jameslamb]

just don't bother

To be clear, for anyone finding this from search...LightGBM absolutely needs to fix this issue and remove uses of load_boston(), so that it can be tested in environments with scikit-learn>=1.2.

Since this is the second comment like this, I'm locking this thread. To be clear:

• there are ethical problems with the boston housing dataset
• LightGBM's tests no longer rely on the boston housing dataset, and that's not going to change
