cannot import module BaggingClassifier

[avilella]

I tried to install scikit-mdr on an Ubuntu 14.04 Linux via pip install but got this error below. To make sure it wasn't a versions issue with scikit-learn, I did a sudo pip install -U scikit-learn, which completed successfully, then tried to load MDR on a python console. See below.

Any ideas?

One of the scikit-MDR algorithms uses scikit-learn's BaggingClassifier, which should be available in your installation of scikit-learn.

What version of scikit-learn is installed?

import sklearn
print sklearn.__version__

That explains it. The latest version of scikit-learn is 0.19, and the BaggingClassifier was probably added after 0.14.1.

If you use the Anaconda distribution, I believe they have scikit-learn up-to-date for Python 2.7.
