I download the gpu version from  http://download.pytorch.org/whl/cu80/torch-0.4.0-cp36-cp36m-win_amd64.whl  3(C:\ProgramData\Anaconda3)
rename it and install it with
E:\software\pylib>pip install torch-0.4.0-cp36-cp36m-win_amd64_cu80.whl
Error occurs:
torch-0.4.0-cp36-cp36m-win_amd64_cu80.whl is not a supported wheel on this platform.
