If :attr:`device` is a torch.device object, returns the device index if it is a MTIA device. Note that for a MTIA device without a specified index, i.e., ``torch.device('mtia')``, this will return the current default MTIA 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 MTIA device if :attr:`optional` is ``True``. )mtiacpuz(Expected a mtia or cpu device, but got: rz!Expected a mtia device, but got: ) isinstanceintstrtorchrtype ValueErrorZjitZ is_scriptingridx_torch_get_device_index)rrrrC/var/www/html/venv/lib/python3.8/site-packages/torch/mtia/_utils.pyr s       r)FF)typingrr Z torch._utilsrrboolr rrrrs
