Not able to import PolynomialFeatures, make_pipeline in Scikit-learn

Question

I'm not able to import the following modules in an ipython notebook:

from sklearn.preprocessing import PolynomialFeatures

from sklearn.pipeline import make_pipeline

The following error pops up

ImportError: cannot import name PolynomialFeatures

The same error also appears for make_pipeline.

I'm a newbie in scikit-learn, please help out.

I'm using the miniconda installation of python and the version number for scikit-learn is 0.14.1.

Answer 1

Polynomial Features is included for next version of scikit-learn and is not available in 0.14.1. Please update to 0.15-git if you want to use it. The same holds for make pipeline.

To get the bleeding edge version:

git clone git://github.com/scikit-learn/scikit-learn.git

python setup.py build_ext --inplace
