class_docstr: CoreML internal representation of a torch IR node.
  Can construct itself from a provided torchIR node or manually constructed with
  args for testing.
  
  See InternalTorchIRGraph for the motivation behind this structure.
  
      Arguments:
          node: The torch._C.Node to convert, or None.
          parent: The InternalTorchIRGraph/Block this node belongs to.
          attr: If @node is not specified, the dict of named attributes.
          inputs: If @node is not specified, the list of input symbols.
          outputs: If @node is not specified, the list of output symbols.
          kind: If @node is not specified, the kind (op) of the node.
          blocks: If @node is not specified, the list of InternalTorchIRBlock.
