Question

我正在Azure中建立循环神经网络：

model = Sequential()


model.add(GRU(units=512,
                return_sequences=True,
                input_shape=(None, x1,)))

  model.add(Dense(y1, activation='sigmoid'))

但是我得到了错误：

TypeError: while_loop() got an unexpected keyword argument 'maximum_iterations'

我不是cretin，但我认为我可能正在做一些当前版本的TensorFlow＆Keras中已贬值的事情，例如在this示例中，发生了类似的错误，并指出了此类错误。我正在Jupyter Azure平台中使用Python 3.6，这也意味着我不确定我正在使用哪个版本的Keras和TensoFlow。

我完整的断网错误消息是：

TypeError: while_loop() got an unexpected keyword argument 'maximum_iterations'

我还从this教程中学到了WARNING:tensorflow:From keep_dims is deprecated, use keepdims instead。如果这是有效的，我该怎么办？

这也许有些直截了当，但我很困惑，对此的帮助将不胜感激。

Answer 1

!pip uninstall keras
!pip install keras==2.1.2

现在可以正常工作

TypeError：while_loop（）在Jupyter Azure中获得了意外的关键字参数'maximum_iterations'
