Input functions take an arbitrary data source (in-memory data sets, streaming data, custom data format, and so on) and generate Tensors that can be supplied to TensorFlow models. More concretely, input functions are used to: Configure how data is drawn during training (shuffling, batch size, epochs, etc.)
