operator fusion.
  * **strict** ("bool", optional) -- run the tracer in a strict
    mode or not (default: "True"). Only turn this off when you
    want the tracer to record your mutable container types
    (currently "list"/"dict") and you are sure that the container
    you are using in your problem is a "constant" structure and
    does not get used as control flow (if, for) conditions.

  * **example_kwarg_inputs** (*dict**, **optional*) -- This
    parameter is a pack of keyword arguments of example inputs
    that will be passed to the function while tracing. Default:
    "None". Either this argument or "example_inputs" should be
    specified. The dict will be unpacking by the arguments name of
    the traced function. If the keys of the dict don't not match
    with the traced function's arguments name, a runtime exception
    will be raised.

Returns:
      If func is nn.Module or "forward" of nn.Module, trace
