ImportError when importing skimage subpackages

[Weixun Goh]

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.
