Backends (torch.backends) documentation/tutorial?

Is there any official documentation on torch.backends? I only recently discovered the existence of torch.backends.cudnn.benchmark. And now I’m wondering what else I’m missing. What’s more, there doesn’t seem to be anything in the documentation on torch.backends (searching for cudnn is the documentation turns up no results), and any Google searches I’ve tried only reveals disconnected forum answers and Github issues. Is there any real documentation for backends? If not, does anyone know of an unofficial tutorial or overview of backends that exists?


I have also encountered this problem rencently, and I have not figured out yet.
