Code before:
        Determines whether a tip is added to the end of the line.
    tip_width : :class:`float`
        The width of the tip.
    tip_height : :class:`float`
        The height of the tip.
    include_numbers : :class:`bool`
        Determines whether numbers are added to tick marks. The number of decimal places is determined
        by the step size, this default can be overridden by ``decimal_number_config``.
    label_direction : Union[:class:`list`, :class:`numpy.ndarray`]
        The specific position to which number mobjects are added on the line.
    line_to_number_buff : :class:`float`
        The distance between the line and the number mobject.
    decimal_number_config : :class:`dict`
        Arguments that can be passed to :class:`~.numbers.DecimalNumber` to influence number mobjects.
    numbers_to_exclude : Union[:class:`list`, :class:`numpy.ndarray`]
        An explicit list of numbers to not be added to the line.
    number_scale_value : :class:`float`
        The size scaling factor for the number mobjects.
    kwargs : Any
        Additional arguments to be passed to :class:`~.Line`.

    Examples
    --------
    .. manim:: NumLineExample

        class NumLineExample(Scene):
            def construct(self):
                l0 = NumberLine(x_range=[-10, 10, 2], length=10, color=BLUE, include_numbers=True, label_direction=UP)
                l0.shift(2 * UP)

                l1 = NumberLine(x_range=[-10, 10, 2], unit_size=0.5, numbers_with_elongated_ticks=[-2, 4], include_numbers=True, number_scale_value=0.5)
                l1.shift(UP)
                num6 = l1.get_number_mobject(6).set_color(RED)

                l2 = NumberLine(
                    x_range=[-2.5, 2.5 + 0.5, 0.5], length=12, decimal_number_config={"num_decimal_places": 2}, unit_size=1.25, include_numbers=True
                )
                l2.shift(DOWN)

                l3 = NumberLine(x_range=[-5, 5 + 1, 1], length=6, include_tip=True, include_numbers=True, rotation=10 * DEGREES)
                l3.shift(2.75 * DOWN)

                self.add(l0, l1, num6, l2, l3)

    Returns
    -------
    NumberLine
        The constructed number line.

This should make the docs render.
