class_docstr: A context manager that ensures that an MXNet network is operating in a
  hybridized / not hybridized mode.
  
  Parameters
  ----------
  net
      The network whose hybrid mode has to be modified within the enclosing
      context.
  hybridize
      A boolean flag indicating whether the hybrid mode should be set or
      not.
  kwargs
      A dictionary of optional arguments to pass to the `hybridize()` call
      of the enclosed `HybridBlock` network.
code: def __init__(
      self,
      net: mx.gluon.HybridBlock,
      hybridize: bool,
      data_batch: Optional[List[mx.nd.NDArray]] = None,
      **kwargs,
  ) -> None:
      self.net = net
      self.required_mode = hybridize
  
      self.original_mode = getattr(net, "_active", False)
      self.data_batch = data_batch
      self.kwargs = kwargs
