Error when training LorA

I want to train my LorA IN kohya, I have Pytorch and Xformers installed and it shows TRUE in the address bar, but when training I get these errors:

ValueError: torch.cuda.is_available() should be True but is False. xformers’ memory efficient attention is only
available for GPU

What have i do?(in Dreambooth i haven`t this problem but there are other problems)

(Windows 10)

Whoever developed the code you’re using stated that it’s only available for GPU. Do you have a GPU and do you have the appropriate Nvidia drivers installed?

Reinstal kohya and it works…)
