chainer.serializers.save_hdf5(filename, obj, compression=4)[source]

Saves an object to the file in HDF5 format.

This is a short-cut function to save only one object into an HDF5 file. If you want to save multiple objects to one HDF5 file, use HDF5Serializer directly by passing appropriate h5py.Group objects.

  • filename (str) – Target file name.
  • obj – Object to be serialized. It must support serialization protocol.
  • compression (int) – Gzip compression level.


Currently save_hdf5() only supports writing to an actual file on file system due to a limitation of HD5F library. See h5py/h5py#687 for details.
