How to compile and install cupy on Windows 10 x64

When I use pip to install cupy on windows 10, the following error reported, I am pretty sure that cupy 1.0.3 can install on windows.

C:\WINDOWS\system32>pip install cupy
Collecting cupy

    Complete output from command python setup.py egg_info:

We now provide wheels of development releases for Windows. Try pip install cupy-cuda92 etc. as in the installation docs.

I tried:

PS E:\Anaconda3python\Scripts> .\pip install .\fastrlock-0.3-cp36-cp36m-win_amd64.whl
Processing e:\anaconda3python\scripts\fastrlock-0.3-cp36-cp36m-win_amd64.whl
Installing collected packages: fastrlock
Successfully installed fastrlock-0.3

then

PS E:\Anaconda3python\Scripts> .\pip install .\cupy-4.0.0b3-cp36-cp36m-win_amd64.whl
Processing e:\anaconda3python\scripts\cupy-4.0.0b3-cp36-cp36m-win_amd64.whl

and it worked for me (Win10 x64). Thanks @hknerdgn
