class_docstr: 3D Keypoints containing Nx3 or BxNx3 points.
  
  Args:
      keypoints: Raw tensor or a list of Tensors with the Nx3 coordinates
      raise_if_not_floating_point: will raise if the Tensor isn't float
code: def clone(self) -> "Keypoints3D":
      return Keypoints3D(self._data.clone(), False)
