tf.keras.utils.HDF5Matrix
Representation of HDF5 dataset to be used instead of a Numpy array.
tf.keras.utils.HDF5Matrix(
    datapath, dataset, start=0, end=None, normalizer=None
)
  THIS CLASS IS DEPRECATED. Training with HDF5Matrix may not be optimized for performance, and might not work with every distribution strategy.
We recommend using https://github.com/tensorflow/io to load your HDF5 data into a tf.data Dataset and passing that dataset to Keras.
| Arguments | |
|---|---|
datapath | 
      string, path to a HDF5 file | 
dataset | 
      string, name of the HDF5 dataset in the file specified in datapath | 
start | 
      int, start of desired slice of the specified dataset | 
end | 
      int, end of desired slice of the specified dataset | 
normalizer | 
      function to be called on data when retrieved | 
| Raises | |
|---|---|
| ImportError if HDF5 & h5py are not installed | 
| Attributes | |
|---|---|
dtype | 
      Gets the datatype of the dataset. | 
ndim | 
      Gets the number of dimensions (rank) of the dataset. | 
shape | 
      Gets a numpy-style shape tuple giving the dataset dimensions. | 
size | 
      Gets the total dataset size (number of elements). |
