'ModuleNotFoundError: No module named 'keras.backend.tensorflow_backend'

I am trying to run the code

import keras

And I am getting this stack trace. I have tried reinstalling keras and tensorflow but nothing in working. Here is the stack trace.

ModuleNotFoundError: No module named 'keras.backend.tensorflow_backend'

Solution 1:^[1]

Try:

pip install tensorflow==2.2.0

and then

pip install Keras==2.2.0

This worked for me with Python 3.7.

Solution 2:^[2]

instead of use something like

    from keras.backend.tensorflow_backend import set_session

Try to use it like

    from keras.backend import set_session

Solution 3:^[3]

In Tensorflow 2.0.0+ versions you should just put "compat.v1" after tf and dont use "tensorflow_backend" name. Like this:

tf.keras.backend.tensorflow_backend.set_session() -> tf.compat.v1.keras.backend.set_session()

Solution 4:^[4]

I tried to use anaconda or pip to install tensorflow and keras, and each method met the same problem.

At last I found the problem is because the version of tensorflow or keras. When I install tensorflow==2.2 and keras==2.4.3(latest), no matter which tools I used I will meet this problem.When I install tensorflow==1.14 and keras==2.2, the code works well.

My python version is 3.5.2 under ubuntu 16.04

Solution 5:^[5]

Just install tensorflow 2.1.0 or 2.2.0 It already has Keras inside. Dont mix using pip and conda. Carry on with what you have started.

pip install tensorflow==2.2.0

or,

conda install tensorflow==2.2.0

Solution 6:^[6]

Uninstall Keras and reinstall the version 2.2.0 in your system, it will definately work with Tensorflow 2.2. Then you won't have to downgrade you tensorflow ie. less pain of changing codes ;)

pip uninstall keras
pip install Keras==2.2.0

For my case, I had Python 3.7(latest bug fix)

Solution 7:^[7]

for tensorflow==2.4.1 this works:

from tensorflow.python.keras.backend import set_session
