docstring: Get the inputs of given node according to partition graphs.
  
      Args:
        node_name: Name of the node.
        is_control: (`bool`) Whether control inputs, rather than non-control
          inputs, are to be returned.
        device_name: (`str`) name of the device. If there is only one device or if
          node_name exists on only one device, this argumnet is optional.
  
      Returns:
        (`list` of `str`) inputs to the node, as a list of node names.
  
      Raises:
        LookupError: If node inputs and control inputs have not been loaded
           from partition graphs yet.
