question: Pytorch Lightning doesn't have CUDA?
context: 🐛 Bug
  Hello, I'm trying to use Pytorch Lightning in order to speed up my ESR GAN renders on Windows 10.
  However, when I ran the installation code and attempt to run Cupscale (which I use as a GUI for ESR GAN), I get an error saying "Pytorch compiled without CUDA".
  Is there a way to choose to install specifically the CUDA version of Pytorch with Lightning install, or are the two incompatible? If the latter is the case, that's not good to hear. If the former, can I have such a code?
answer: @TrocelengStudios ho this seems like you do not have CUDA installed, can you run nvidia-smi?
