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:</div>

<div><br></div><div>&nbsp; &nbsp; python -c 'import skimage; print skimage.__file__'</div><div><br></div><div>If you move up one directory and then start the python interpreter, does the rank import work?</div><div><br></div>

<div>Best,</div><div>-Tony</div></div>
