As mentionned in the official documentation, you cannot have this json file using ~/.keras/keras.json unless you have already run it at least once before. I suggest you to create on with the default configuration: 

{
    "image_dim_ordering": "tf",
    "epsilon": 1e-07,
    "floatx": "float32",
    "backend": "tensorflow"
}

  • Can you please explain where to put the json file in this post? Thanks! http://stackoverflow.com/questions/40310035/how-to-change-keras-backend – George Liu Oct 28 '16 at 17:22

If you have run Keras at least once, you will find the Keras configuration file at:

$HOME/.keras/keras.json

If it isn't there, you can create it.

NOTE for Windows Users: Please change $HOME with %USERPROFILE%.

Get a more recent version of tensorflow. The default tensorflow installed by conda is currently 0.9.0, which too old. Try upgrading for instance with conda upgrade -c conda-forge tensorflow or pip install tensorflow --upgradeif you don't use conda.
