The key is to keep your environment clean and do not try to install through PyCharm because it is using PyPI on which the win packages are not hosted.

Remove any python that appears in PATH (Not needed if you use conda).
Install Anaconda3 / MiniConda3 / Python >= 3.5.0 / 3.6.1 / 3.7.0 (For conda ones, don’t add them into PATH).
Open Anaconda Prompt if you use conda.
Type in the commands using the wizard in https://pytorch.org/ 105 (Conda ones are preferred.)
If you want to use PyCharm, don’t forget to set the environment to the newly-installed one.
