AttributeError: невозможно установить атрибут в python3

Question

Tring для запуска на Google Collab:

  params.dropoutkeepprobs = DropoutKeepProbs(
        self.q_conv_keep_prob,
        self.q_dense_keep_prob,
        self.q_gru_keep_prob
    )
    self.q = DeepSense(params, self.logger, self.sess, self.config, name=Q_NETWORK)

полная программа: https://github.com/samre12/deep-trading-agent/blob/master/code/model/agent.py

Я пытался запустить https://github.com/samre12/deep-trading-agent в Python 3 на Google Colab, появилась эта ошибка. работает на python2 все нормально

 self._price_blocks.append(normalized_block.as_matrix())
