Recently,I need to install pytorch ,when I check out the website :
download pytorch using pip 1
It shows four different version 9.2,10.1,10.2,11.0 to choose ,And I have cuda version 10.0 and driver version 450 installed on my computer,I thought it would fail to enable gpu when using pytorch ,After I choose 10.1 and use pip to install pytorch and try torch.cuda.is_available() and it returns True
I have two questions:

Why does everything turn out to be working even my cuda version is not the same as any of one I mentioned ?
What’s the difference between choosing cuda verison 9.2,10.1,10.2,11.0 ?
