The schema is inferred from the
    function's type hints, and can be used to define a new operator.

    We make the following assumptions:

    * None of the outputs alias any of the inputs or each other.
    * | String type annotations "device, dtype, Tensor, types" without library specification are
      | assumed to be torch.*. Similarly, string type annotations "Optional, List, Sequence, Union"
      | without library specification are assumed to be typing.*.
    * | Only the args listed in ``mutates_args`` are being mutated. If ``mutates_args`` is "unknown",
      | it assumes that all inputs to the operator are being mutates.

    Callers (e.g. the custom ops API) are responsible for checking these assumptions.

    Args:
        prototype_function: The function from which to infer a schema for from its type annotations.
        op_name (Optional[str]): The name of the operator in the schema. If ``name`` is None, then the
            name is not included in the inferred schema. Note that the input schema to
            ``torch.library.Library.define`` requires a operator name.
        mutates_args ("unknown" | Iterable[str]): The arguments that are mutated in the function.

    Returns:
        The inferred schema.

    Example:
        >>> def foo_impl(x: torch.Tensor) -> torch.Tensor:
        >>>     return x.sin()
        >>>
        >>> infer_schema(foo_impl, op_name="foo", mutates_args={})
        foo(Tensor x) -> Tensor
        >>>
        >>> infer_schema(foo_impl, mutates_args={})
        (Tensor x) -> Tensor
