Hi Riley

I should have checked your stacktrace earlier.  It looks like Matplotlib is responsible.  What version of that package are you running, and can you try and upgrade to the latest version?

Thanks!  This works perfectly on my system.  Can you share the output of:

import skimage
print(skimage.__version__)

import numpy
print(numpy.__version__)

import scipy
print(scipy.__version__)

Thanks!

Ok - I've attached the code, and the images necessary to run it, in a tarball. The images (and the code) are taken from the skimage-tutorials available on github at https://github.com/scikit-image/skimage-tutorials - specifically lectures/adv3_panorama-stitching.ipynb.
Thanks!
