How to import keras from tf.keras in Tensorflow?

Question

import tensorflow as tf
import tensorflow 

from tensorflow import keras
from keras.layers import Dense

I am getting the below error

from keras.layers import Input, Dense
Traceback (most recent call last):

  File "<ipython-input-6-b5da44e251a5>", line 1, in <module>
    from keras.layers import Input, Dense

ModuleNotFoundError: No module named 'keras'

How do I solve this?

Note: I am using Tensorflow version 1.4

Answer 1

Use the keras module from tensorflow like this:

import tensorflow as tf

Import classes

from tensorflow.python.keras.layers import Input, Dense

or use directly

dense = tf.keras.layers.Dense(...)

EDIT Tensorflow 2

from tensorflow.keras.layers import Input, Dense

and the rest stays the same.

Answer 2

I have a similar problem importing those libs. I am using Anaconda Navigator 1.8.2 with Spyder 3.2.8.

My code is the following:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from tensorflow.python.keras.models import Sequential
from tensorflow.python.keras.layers import InputLayer, Input
from tensorflow.python.keras.layers import Reshape, MaxPooling2D
from tensorflow.python.keras.layers import Conv2D, Dense, Flatten

I get the following error:

from tensorflow.python.keras.models import Sequential

ModuleNotFoundError: No module named 'tensorflow.python.keras'

I solve this erasing tensorflow.python

With this code I solve the error:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from keras.models import Sequential
from keras.layers import InputLayer, Input
from keras.layers import Reshape, MaxPooling2D
from keras.layers import Conv2D, Dense, Flatten

Answer 3

Try from tensorflow.python import keras

with this, you can easily change keras dependent code to tensorflow in one line change.

You can also try from tensorflow.contrib import keras. This works on tensorflow 1.3

Edited: for tensorflow 1.10 and above you can use import tensorflow.keras as keras to get keras in tensorflow.

To make it simple I will take the two versions of the code in keras and tf.keras. The example here is a simple Neural Network Model with different layers in it.

In Keras (v2.1.5)

from keras.models import Sequential
from keras.layers import Dense

def get_model(n_x, n_h1, n_h2):
    model = Sequential()
    model.add(Dense(n_h1, input_dim=n_x, activation='relu'))
    model.add(Dense(n_h2, activation='relu'))
    model.add(Dropout(0.5))
    model.add(Dense(4, activation='softmax'))
    model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
    print(model.summary())
    return model

In tf.keras (v1.9)

import tensorflow as tf

def get_model(n_x, n_h1, n_h2):
    model = tf.keras.Sequential()
    model.add(tf.keras.layers.Dense(n_h1, input_dim=n_x, activation='relu'))
    model.add(tf.keras.layers.Dense(n_h2, activation='relu'))
    model.add(tf.keras.layers.Dropout(0.5))
    model.add(tf.keras.layers.Dense(4, activation='softmax'))
    model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
    print(model.summary())

    return model

or it can be imported the following way instead of the above-mentioned way

from tensorflow.keras.layers import Dense

The official documentation of tf.keras

Note: TensorFlow Version is 1.9

this worked for me in tensorflow==1.4.0

from tensorflow.python import keras

Answer 6

I had the same problem with Tensorflow 2.0.0 in PyCharm. PyCharm did not recognize tensorflow.keras; I updated my PyCharm and the problem was resolved!

Answer 7

Starting from TensorFlow 2.0, only PyCharm versions > 2019.3 are able to recognise tensorflow and keras inside tensorflow (tensorflow.keras). Francois Chollet himself (author of Keras) recommends that everybody switches to tensorflow.keras in place of plain keras.

There is also one important mentioning here:

IMPORTANT NOTE FOR TF >= 2.0

There (this) is an ongoing issue with JetBrains (in fact from TensorFlow side), it seems that this error comes up from time to time (https://youtrack.jetbrains.com/issue/PY-53599).

It sometimes happens that PyCharm is not able to correctly import/recognize keras inside tensorflow or other imports.

Depending on Python + TF + PyCharm versions, you may have to alternate between the following import types:

from tensorflow.keras.models import Model

OR

from tensorflow.python.keras.models import Model

Answer 8

Its not quite fine to downgrade everytime, you may need to make following changes as shown below:

Tensorflow

import tensorflow as tf

#Keras
from tensorflow.keras.models import Sequential, Model, load_model, save_model
from tensorflow.keras.callbacks import ModelCheckpoint
from tensorflow.keras.layers import Dense, Activation, Dropout, Input, Masking, TimeDistributed, LSTM, Conv1D, Embedding
from tensorflow.keras.layers import GRU, Bidirectional, BatchNormalization, Reshape
from tensorflow.keras.optimizers import Adam

from tensorflow.keras.layers import Reshape, Dropout, Dense,Multiply, Dot, Concatenate,Embedding
from tensorflow.keras import optimizers
from tensorflow.keras.callbacks import ModelCheckpoint

The point is that instead of using

from keras.layers import Reshape, Dropout, Dense,Multiply, Dot, Concatenate,Embedding

you need to add

from tensorflow.keras.layers import Reshape, Dropout, Dense,Multiply, Dot, Concatenate,Embedding
