What is your Cython version? Older versions of Cython don't like relative imports in .pyx files. I suspect the Cython extensions in the package are not built. Are your pip installs completing successfully? Our full installation instructions are located here: http://scikit-image.org/docs/stable/install.html Also, make sure your pip installs are going into `/usr/local/lib/python2.7/dist-packages/`. If not, then an older, unbuilt version of skimage in that location may be ahead of your newer ones on the PYTHONPATH so your subsequent, successful installations are not being used.

I'm running into some issues after upgrading scikit-image, so I tried uninstalling and reinstalling, and it just doesn't seem to work.
When I try to import skimage.feature, I run into the following issue:

Same thing happens with filters and filter

Importing skimage.viewer gives me:
ImportError: cannot import name _coords_inside_image
Those are all that I have tried. skimage.utils works fine.
I'm running the numpy and scipy packages provided by Ubuntu, and have tried both installing scikit-image using the pip packages as well as downloading from github then installing pip.
Would be great if someone could shed some light on this.
