My first guess would the the PYTHONPATH... Could you have a look to see if adding scikits-image root directory makes any difference?

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.

Hey Brickle,

Do you get the same error if you just call:

    from scipy import signal

If so, you may need to rebuild scipy.
