Hi Tony, You're absolutely right, that was the issue. Thanks very much. Now to learn how to use scikit-image :-) Best, Parand On Friday, December 14, 2012 11:37:32 AM UTC-8, Tony S Yu wrote:

Hi Tony,

Installation steps:

This is on OS X 10.8.2, Python 2.7.2:

- I setup a virtualenv and activated that virtual env. - I cloned the scikit-image git repository - I installed:

$ python ./setup.py install ... Installed /Users/parand/Projects/Receipts/pyenv/lib/python2.7/site-packages/scikit_image-0.8dev-py2.7-macosx-10.8-intel.egg Processing dependencies for scikit-image==0.8dev Finished processing dependencies for scikit-image==0.8dev

$ python Python 2.7.2 (default, Jun 20 2012, 16:23:33) [GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin

...

...

...

Hi Parand,

If those commands are exactly as you copied them above, it looks like you're running the python interpreter from within the root scikit-image directory. Since python prepends the path of the working directory to the python path, you're actually importing the skimage package from that directory---not the one you just installed (i.e. the one in site-packages). You can check which you're running with:

python -c 'import skimage; print skimage.__file__'

If you move up one directory and then start the python interpreter, does the rank import work?

Best, -Tony
