class_docstr: Deserializer for HDF5 format.
  
  This is the standard deserializer in Chainer. This deserializer can be used
  to read an object serialized by :class:`HDF5Serializer`.
  
  Args:
      group (h5py.Group): The group that the deserialization starts from.
      strict (bool): If ``True``, the deserializer raises an error when an
          expected value is not found in the given HDF5 file. Otherwise,
          it ignores the value and skip deserialization.
code: def __getitem__(self, key):
      name = self.group.name + "/" + key
      try:
          group = self.group.require_group(name)
      except ValueError:
          # require_group raises ValueError if there does not exist
          # the given group and the file is read mode.
          group = None
      return HDF5Deserializer(group, strict=self.strict)
