    object, a Python integer, or ``None``.

    If :attr:`device` is a torch.device object, returns the device index if it
    is a CUDA device. Note that for a CUDA device without a specified index,
    i.e., ``torch.device('cuda')``, this will return the current default CUDA
    device if :attr:`optional` is ``True``. If :attr:`allow_cpu` is ``True``,
    CPU devices will be accepted and ``-1`` will be returned in this case.

    If :attr:`device` is a Python integer, it is returned as is.

    If :attr:`device` is ``None``, this will return the current default CUDA
    device if :attr:`optional` is ``True``.
