How to use the coremltools.converters.nnssa.commons.builtins.annotate.annotate function in coremltools

        @annotate(delay_type.bool, other=delay_type_float)
        def __gt__(self, other):
            return bool(self.val > other.val)

        @annotate(delay_type.double)
        def __exp__(self):
            return math.exp(self.val)

        @annotate(delay_type.bool, other=delay_type_float)
        def __ne__(self, other):
            return bool(self.val != other.val)

        @annotate(delay_type.double)
        def __double__(self):
            return float(self.val)

        @annotate(delay_type_int, other=delay_type_int)
        def __add__(self, other):
            assert (isinstance(other, int))
            return int(self.val + other.val)

        @annotate(delay_type_float, other=delay_type_float)
        def __mod__(self, other):
            assert (isinstance(other, double))
            return double(self.val % other.val)

    @annotate(delay_type.bool, other=delay_type.bool)
    def __eq__(self, other):
        return bool(self.val == other.val)

        @annotate(delay_type_int, other=delay_type_int)
        def __mod__(self, other):
            assert (isinstance(other, int))
            return int(self.val % other.val)

        @annotate(delay_type_float)
        def __double__(self):
            return float(self.val)

        @annotate(delay_type_float, other=delay_type_float)
        def __mul__(self, other):
            assert (isinstance(other, double))
            return double(self.val * other.val)
