Configuring Keras

Keras has a very minimalist configuration file. Let's load it with a vi session. The parameters are very simple:

Parameters	Values
image_dim_ordering	Can be either tf for the TensorFlow image ordering or th for Theano image ordering
epsilon	The epsilon value used during computation
floatx	Can be either float32 or float64
backend	Can be either tensorflow or theano

The image_dim_ordering of th value gives you a somewhat non-intuitive dimension ordering for images (depth, width, and height), instead of (width, height, and depth), for tf. The following are the default parameters in my machine:

Note

If you install a GPU-enabled TensorFlow version, then Keras will automatically use your configured GPU when TensorFlow is selected as the backend.
