Hi, Sorry, I've been updating the travis-ci build, and in particular the wheel sources, over at : https://github.com/scikit-image/scikit-image/pull/2451 As part of that, I built a new version of the pyside wheel, for our wheel repository, and this broke one of the current scikit image travis build matrix entries: https://travis-ci.org/scikit-image/scikit-image/jobs/191999862 That break will be fixed when #2451 is merged - just letting y'all know. Cheers, Matthew
