Python VW Hyperopt

Я пытаюсь найти гиперпараметры моей модели VW, используя VW Hyperopt https://github.com/VowpalWabbit/vowpal_wabbit/blob/master/utl/vw-hyperopt.py

Но после установки всех необходимых пакетов я все еще получаю эту ошибку:

Любые указания о том, как избавиться от этой ошибки, будут действительно полезны.Я использую Python2
