tf.keras.utils.Sequence() Base object for fitting to a sequence of data, such as a dataset. Every Sequence must implement the __getitem__ and the __len__ methods. If you want to modify your dataset between epochs you may implement on_epoch_end . The method __getitem__ should return a complete batch. Notes:

Sequence keras.utils.data_utils.Sequence() 序列数据的基类，例如一个数据集。 每个Sequence必须实现__getitem__和__len__方法. 下面是一个例子： from skimage.io import imread from skimage.transform import resize import numpy as np __Here, `x_set` is list of path to the images__ # and `y_set` are the associated classes.

keras.utils.io_utils.HDF5Matrix (datapath, dataset, start=0, end=None, normalizer=None) Representation of HDF5 dataset which can be used instead of a Numpy array. Example X_data = HDF5Matrix ('input/file.hdf5', 'data') model.predict (X_data) Providing start and end allows use of a slice of the dataset.
