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``. )cudacpuz(Expected a cuda or cpu device, but got: r z!Expected a cuda device, but got: ) isinstanceintstrtorchrtype ValueErrorjit is_scriptingr idx_torch_get_device_index)rrrs BC:\Projects\Historical\venv\Lib\site-packages\torch/cuda/_utils.pyrr s &# &#&f%%&%,''K  K{/11 !TF!T!TUUU2 [F " "IIIJJ J 9 ! ! # # fej/ 0 0 :  "68Y ? ??)FF)typingrr torch._utilsrrboolr rrrs FEEEEE
