tensors or (possibly nested) tuples that contain tensors. When a
      module is passed torch.jit.trace, only the "forward" method is
      run and traced (see "torch.jit.trace" for details).
Keyword Arguments:
      * example_inputs (tuple or torch.Tensor or None,
        optional) -- A tuple of example inputs that will be passed
        to the function while tracing. Default: "None". Either this
        argument or "example_kwarg_inputs" should be specified. The
        resulting trace can be run with inputs of different types and
        shapes assuming the traced operations support those types and
        shapes. example_inputs may also be a single Tensor in which
        case it is automatically wrapped in a tuple. When the value is
        None, "example_kwarg_inputs" should be specified.
  * **check_trace** ("bool", optional) -- Check if the same inputs
    run through traced code produce the same outputs. Default:
