fix for crash when running #12924 without --device-id

        # enabling benchmark option seems to enable a range of cards to do fp16 when they otherwise can't

        # see https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/4407

        device_id = (int(shared.cmd_opts.device_id) if shared.cmd_opts.device_id is not None and shared.cmd_opts.device_id.isdigit() else 0) or torch.cuda.current_device()

        if torch.cuda.get_device_capability(device_id) == (7, 5) and torch.cuda.get_device_name(device_id).startswith("NVIDIA GeForce GTX 16"):
