My first guess would the the PYTHONPATH... Could you have a look to see if adding scikits-image root directory makes any difference? Brian On Sep 23, 2012 8:48 AM, "bricklemacho" <bricklemacho@gmail.com> wrote:

I am trying to run the plot_hog.py demo an I get the error below. If I copy skimage/feature/hog.py and import form the current working directory the plot_hog.py runs.

The error seems to be something to do with importing match_template. Not sure where to start , all packages were installed via macports. Is this a scikits-image, scipy or a macports issue?

Any help appreciated, error message below.
