Error with TensorFlow MNIST

Question

I am running OS X El Capitan and python 2.7.10. I installed CPU only version of TensorFlow using pip(following this), but when I try to run the MNIST example it gives me an ImportError at

from tensorflow.examples.tutorials.mnist import input_data

The traceback is:
