pip install cupy エラー

前提・実現したいこと

pip install cupy がエラーで実現できません。

とりあえず下記環境で利用しようとしています
Windows 10
Visual Studio 2015　Community
CUDA　9.0
CuDNN 7.0

Cupy がインストールできたら、Chainer のインストールをを行う予定ですが、うまく実現できません。インストール方法についてご教授ください。

よろしくお願いいたします。

発生している問題・エラーメッセージ

-> Check your CFLAGS environment variable.
CFLAGS の環境変数をしなおす必要があるように思うのですが、CFLAGS がどこにあるのかわかりません。また、設定の仕方がわかりません。

試したこと

WINDOWS - SYSTEM - 詳細設定　－　環境変数　に
変数名　CFAGS
変数値　C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\include

と設定してみましたが効果はありませんでした。

補足情報（FW/ツールのバージョンなど）

上記の通りです。

エラーの原因は

ERROR: CUDA could not be found on your system.

とあるようにCUDAがみつからないことにあるようです。既にインストール済みということなので、CUDAのインストール場所などを示す環境変数の設定が不足していることが原因と思われます。
エラーメッセージによると

Please refer to the Installation Guide for details:
https://docs-cupy.chainer.org/en/stable/install.html

ということで参照にしてはいかがでしょうか。
念のためにCUDAインストール時に参照内容をチェックして環境変数が正しく設定されていることを確認したほうがいいでしょう。

ご回答ありがとうございます。 CUDA　9.0、CuDNN 7.0　を入れなおした結果、あと少しというところまで進められるようになりました。もう少しだと思うのですが、まだ完了はしておりません。ーーーーーーーーーーーーーーーーーーーーーーーー PS C:\Users\harus> pip install cupy==2.3.0 --no-cache-dir Collecting cupy==2.3.0 Downloading https://files.pythonhosted.org/packages/51/ce/9c4789dd570935c5fd8c9f71aa4e0761aaaef195ef1f017e4174e7c266dc/cupy-2.3.0.tar.gz (1.9MB) 100% |################################| 1.9MB 1.6MB/s Requirement already satisfied: numpy>=1.9.0 in c:\users\harus\anaconda2\lib\site-packages (from cupy==2.3.0) (1.11.1) Requirement already satisfied: six>=1.9.0 in c:\users\harus\anaconda2\lib\site-packages (from cupy==2.3.0) (1.10.0) Requirement already satisfied: fastrlock>=0.3 in c:\users\harus\anaconda2\lib\site-packages (from cupy==2.3.0) (0.3) Installing collected packages: cupy Running setup.py install for cupy ... error Complete output from command c:\users\harus\anaconda2\python.exe -u -c "import setuptools, tokenize;__file__='c:\users\harus\appdata\local\temp\pip-install-qzwcb4\cupy\setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record c:\users\harus\appdata\local\temp\pip-record-rx3ndg\install-record.txt --single-version-externally-managed --compile: ************************************************** *** WARNING: Cannot find nvToolsExt. nvtx was disabled. ************************************************** Options: {'profile': False, 'annotate': False, 'linetrace': False, 'no_cuda': False} Include directories: ['C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\include', 'C:\Program Files\NVIDIA Corporation\NvToolsExt\include'] Library directories: ['C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin', 'C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\lib\x64', 'C:\Program Files\NVIDIA Corporation\NvToolsExt\lib\x64'] a.cpp C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\include\cuda_runtime.h : warning C4819: The file contains a character that cannot be represented in the current code page (932).
