title: Importing scikit-learn in ipython/Jupyter notebook
body: <p>I am able to import scikit-learn from python or ipython console (both python 2.7 and 3.5), but when I do <code>import sklearn</code> within an ipython notebook (again, either 2.7 or 3.5) I get the error message below. How can I fix this? </p>
