backend = gs.vulkan for AMD Radeon

[Quantonamor]

Hey there,
i am new to anything AI and setup everything - however, as i only have a Radeon RX 5700 i cannot use CUDA. I tried to set gs.vulkan (as it is stated in the documentary) but it just says "genesis.GenesisException: cuda device not available". After checking the code a bit, i just saw that it checks only for cuda if one does not set backend = gs.cpu (In Utils/misc.py get_gpu_device()). Is it not supported or do i do anythinf wrong?
Thanks!
