Question

我正在尝试从Datalab实例中的TensorFlow contrib包导入Keras（我使用的是Tensorflow 1.1.0版本和Python 2.7）

from tensorflow.contrib.keras.python.keras.regularizers import l1,l2
from tensorflow.contrib.keras.python.keras.models import Sequential, load_model
from tensorflow.contrib.keras.python.keras.layers import Dense, Dropout, Activation
from tensorflow.contrib.keras.python.keras.constraints import max_norm
from tensorflow.contrib.keras.python.keras.optimizers import RMSprop, Adam
from tensorflow.contrib.keras.python.keras.layers.normalization import BatchNormalization

但是我收到以下错误：

ImportErrorTraceback (most recent call last)

ImportError: cannot import name activations

我尝试将Tensorflow升级到1.2.1版本，但它仍无效。

为什么我收到此错误的任何想法？谢谢！

我将回答我自己的问题：似乎每次重新启动实例时，安装在Datalab实例中的python包都被重置为默认包（我还没有发现为什么会发生这种情况），所以我正在执行代替1.0.0 tensorflow版本的代码。我刚刚在一个单元格中写道：

!pip install tensorflow==1.1.0

我重新启动了Datalab内核（重启会话按钮）。之后，一切正常，我可以从Tensorflow contrib包中导入Keras。

无法从Datalab中的TensorFlow contrib包导入Keras
