Unfortunately, from the PyQt website's FAQ:

Do I need the commercial version of PyQt?
 The easiest way to answer this is to ask "Am I using the commercial edition
of Qt?". If so then you also need the commercial version of PyQt. If you
are using the GPL version of Qt, then you only need the GPL version of
PyQt.
