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. Best, -Tony
