Installing Keras

In the sections to follow, we will show how to install Keras on multiple platforms.

Step 1 — install some useful dependencies

First, we install the numpy package, which provides support for large, multidimensional arrays and matrices as well as high-level mathematical functions. Then we install scipy, a library used for scientific computation. After that, it might be appropriate to install scikit-learn, a package considered the Python Swiss army knife for machine learning. In this case, we will use it for data exploration. Optionally, it could be useful to install pillow, a library useful for image processing, and h5py, a library useful for data serialization used by Keras for model saving. A single command line is enough for installing...
