The type annotation npt.NDArray[np.int_] violates Python Guide typing requirements. Use typing_extensions for back-porting newer typing features and add from __future__ import annotations. Additionally, np.int_ is deprecated in newer numpy versions and should be replaced with specific integer types like np.int64.
