Sorry for the really late reply on this. Actually, the demo should have
printed instructions to the terminal in that version.

In any case, getting the user to press enter wasn't great for usability. I just
changed this demo<https://github.com/tonysyu/scikit-image/commit/230fefa748db13af928e5cf699899efd797d6349>
so
that you press a button to display the watershed segmentation.
