Windows using for fast AI

like a majority of people I do use windows 10 computer, please share how to install pytorch on windows.
I tried several advices from internet , but nohting works so far

I see from https://pytorch.org/ and https://medium.com/syncedreview/pytorch-releases-major-update-now-officially-supports-windows-2426c9f29d2d
they did it
if somebody tried? By the way how to find what CUDA version by computer has?
I have this
C:\Users\sndr\Anaconda3\pkgs\cudatoolkit-9.0-1
dose it mean I do have CUDA 9?
thanks
