windowsでanacondaを使って，cupyを実行したい

cupyを実装したいと思っています

conda install cupy
で，インストールまではできたのですが，
インタプリタで以下のように実行すると

python
1>>> import cupy as cp
2>>> A = cp.arange(9).reshape(3, 3).astype('f')
3C:\Users\ユーザ名\Anaconda3\envs\py3.5\lib\site-packages\cupy\creation\ranges.py:57: UserWarning: Please set the CUDA path to environment variable `CUDA_PATH`
