each subgraph, recording the test inputs and export options, as
      well as the validation results.
  Parameters:
     **options** (*Optional**[**VerificationOptions**]*) -- The
     verification options.

find_partition(id)
  Find the *GraphInfo* object with the given id.

  Return type:
     *Optional*[*GraphInfo*]

has_mismatch()
  Return True if the subgraph has output mismatch between torch
  and ONNX.

  Return type:
     bool

pretty_print_mismatch(graph=False)
  Pretty print details of the mismatch between torch and ONNX.

  Parameters:
     **graph** (*bool*) -- If True, print the ATen JIT graph and
     ONNX graph.

pretty_print_tree()
  Pretty print *GraphInfo* tree.

  Each node represents a subgraph, showing the number of nodes in
  the subgraph and a check mark if the subgraph has output
  mismatch between torch and ONNX.

  The id of the subgraph is shown under the node. The *GraphInfo*
