I tried to switch Backend with Keras (from TensorFlow to Theano) but did not manage. I followed the temps described here but it doesn\'t work. I created a keras.json in the
For Linux systems, the hidden .keras directory will be created in the user’s home directory. To observe whether or not it has been created, run the following command from your home directory (the -a allows you to see hidden files and directories).
ls –a
If the directory is there, then cd into it and modify the keras.json file. If it’s not there, then create the directory with
mkdir .keras
Then create the file with
touch keras.json
Then edit the file to make the config changes you referenced to change the backend engine to Theano.
This process is covered fully in this video.
