Amandeep, adding '..' to sys.path is an unusual thing to do. That's
relative to the current working directory. What's the source for this?

plain text version:

    import sys
    import os

    if __name__ == '__main__':
        sys.path.insert(0, "..")
    else:
        sys.path.insert(0, os.path.join(
            os.path.split(__file__)[0], '..'))
