How to Enable GPU/CUDA Device for KokoroEngine?

[Loik00]

I'm trying to run KokoroEngine with GPU acceleration but can't find device
parameter documentation.

from RealtimeTTS import KokoroEngine

• This fails - no device parameter
  engine = KokoroEngine(device="cuda") # TypeError: unexpected keyword argument 'device'

Anyone knows how to force KokoroEngine to use CUDA/GPU instead of CPU?

Which OS are you using ?

Im using Windows 11 with laptop GPU (RTX 4060 8GB vram), CUDA 12.1 and PyTorch 2.5.1+cu121

Please try in WSL if not using it currently > Im using Windows 11 with laptop GPU (RTX 4060 8GB vram), CUDA 12.1 and PyTorch 2.5.1+cu121

I'm not, that will probably serve me well, thank you.

Turns out kokoro automatically checks for for cuda device, but the RealtimeTTS wrapper doesn't do that automatically, for me anyway. - Fix was to set torch.cuda.set_device(0)
