Installing the backend engine

After installing the dependencies, it is necessary to select the backend engine and proceed with its installation. Keras developers recommend the TensorFlow backend. This is the one set by default.

Links to installation instructions for all the available backends are listed in the following list:

• TensorFlow installation instructions: https://www.tensorflow.org/install/
• Theano installation instructions: http://deeplearning.net/software/theano/install.html#install
• CNTK installation instructions: https://docs.microsoft.com/en-us/cognitive-toolkit/setup-cntk-on-your-machine

In all cases, we can use the pip command to install the correct packages.
