When sift is not present sift.py creates an empty .sift file. This empty file raises than an exception the next time learn.py is run even if the sift executable is now present.

Example error message: IOError: /..../data_scv/train/Leopards/image_0001.jpg.sift wrong file path or file empty

Bug is caused by using a pipe > to write the output of sift to a file. Bug location in sift.py
