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: rz!Expected a cuda device, but got: ) isinstanceintstrtorchrtype ValueErrorjit is_scriptingridx_torch_get_device_index)rrrre/var/www/html/construction_image-detection-poc/venv/lib/python3.10/site-packages/torch/cuda/_utils.pyr s        r)FF)typingrr torch._utilsrrboolr rrrrs
