Hi @piggy4eva ,
Graphics devices go through Vulkan rather than CUDA. You need to use vulkaninfo to figure out the id for your device. Here’s the note from the README:
graphics_device_id=GRAHPICS_DEVICE_ID- Which Vulkan graphics device ID to use for rendering. Defaults to 0. Note - this may be different from CUDA device ID, and does not follow PyTorch-like device syntax.
Take care,
-Gav
