New in numpy version 2: numpy int types aren't promoted to bigger types.
    >>> np.uint8(1) + 255
    <python-input-21>:1: RuntimeWarning: overflow encountered in scalar add
    np.uint8(0)

    >>> np.__version__
    '2.2.4'


The old numpy 1.24 used to promote numpy int types to 64-bit:

    >>> type(np.uint8(1) + 1)
    <class 'numpy.int64'>
    >>> np.__version__
    '1.24.2'
