        <br>
        Many thanks for this information.<br>
        <br>
        I had intended to abandon PyQt5 and use PyQt4 only, but your
        message below leads to another try.<br>
        <br>
        I have installed PyQt4, from the binary, and when I attempt to
        download PyQt5, from the binary, I get a message "A copy of
        PyQt4 for Python v3.3 is already installed in Python 33 and must
        be uninstalled first".<br>

    <big>In these circumstances, is there workaround so that one may use
