keras Dealing with large training datasets using Keras fit_generator, Python generators, and HDF5 file format
Introduction
Machine learning problems often require dealing with large quantities of training data with limited computing resources, particularly memory. It is not always possible to load an entire training set into memory. Fortunately, this can be dealt with through the use of Keras' fit_generator method, Python generators, and HDF5 file format.
Remarks
This example assumes keras, numpy (as np), and h5py have already been installed and imported. It also assumes that video inputs and labels have already been processed and saved to the specified HDF5 file, in the format mentioned, and a video classification model has already been built to work with the given input.
