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!
