Put this in

import os.path
HERE = os.path.dirname(os.path.abspath(__file__))

You may also need

HERE = os.path.realpath(HERE)


Almost every module has a global variable __file__. It points to the 
path from which the module was loaded. os.path.abspath() gives you the 
absolute path to the module. os.path.dirname() strips away the file part 
and gives you the path to the directory. os.path.realpath() migt be 
required to eliminate all symbolic links.
