clearly, I am doing something wrong.

Please help!

I had the same problem. Now the problem is fixed. (2020-05-31)


Visited the site pytorch.org
and find "QUICK START LOCALLY" on homepage of pytorch.org. ( it' can find by scroll down little )
Checking the environment form of your system
(ex: Windows, pip, python, ,,)
then, you can see the install command.
"pip install torch===.... "
Copy the install command
and Execute the command at your system.


Good Luck !!
