AttributeError: module 'keras.engine' has no attribute 'input_layer'

问题

I am trying to use google colab!

But I keep running into the problem with keras where it says: AttributeError: module 'keras.engine' has no attribute 'input_layer'

However, checking their github library, there is a input_layer.py within keras/engine.

Also, this works locally, just not on google colab.

Any ideas?

回答1:

The above import works on your local device because you are not using any hardware accelerator (GPU) on your local device. I do not know the reason as to why this import does not work on GPU runtimes. Here are two workarounds for this.

Change the Colab runtime to None and this import will work fine.
I looked at the code of input_layer and found that it has a Input (function) and InputLayer (class). So, If you do not want to change the runtime, you need to refactor things.

Remove

from keras.engine import input_layer.InputLayer
from keras.engine import input_layer.Input

from keras.layers import InputLayer, Input

I wish both do the same thing

I have the same problem with google colab. The error I am getting is:

module 'tensorflow._api.v1.keras' has no attribute 'engine'.

Here is my code:

 import tensorflow as tf
 from tensorflow import keras
 from keras import backend as K

 def reinitLayers(model):
     session = K.get_session()
     for layer in model.layers: 
         if isinstance(layer,keras.engine.network.Network):
             reinitLayers(layer)
....

However there exist keras.engine: https://github.com/tensorflow/tensorflow/tree/master/tensorflow/python/keras/engine
