Hi,
Open up conda prompt from anaconda installation path, then run this command:
conda install pytorch torchvision cudatoolkit=10.0 -c pytorch

Or open oup Powershell (windows native shell) then run the command.
By the way, the PyTorch doc is easy to follow and almost complete, a google query would be great!
