solution:
in file gaussian_model_cf.py
in the end ,add this:

    elif len(out) == 5:
        rendered_image, radii, rendered_depth, rendered_alpha, n_touched= out

        rendered_image = rendered_image.clamp(0, 1)

        # Those Gaussians that were frustum culled or had a radius of 0 were not visible.
        # They will be excluded from value updates used in the splitting criteria.
        return {
            "image": rendered_image,
            "depth": rendered_depth,
            "viewspace_points": screenspace_points,
            "visibility_filter": radii > 0,
            "radii": radii,
            "n_touched": n_touched,
        }
