AttributeError: module 'keras.backend' has no attribute 'backend'

Question

I have TensorFlow installed of version 1.14.0 on my Ubuntu machine. I am trying to run a code with

import keras 

and I get an error

AttributeError: module 'keras.backend' has no attribute 'backend'

I have tried installing specific version of Keras (2.0.8) because I have seen an answer which says Keras 2.0.8 is required for TensorFlow 1.14.0 . But still I get the error.

Answer 1

Seems you have a file in your codebase that interferes with python's own modules, this file is code.py and is being imported inside a system file (pdb.py), rename your code.py to something else and it will probably solve the issue.
