CuDNN install error

I’m setting up CUDA v7.5,and cuDNN v5 Library for Windows 7 with Anaconda2 in windows 8.
I want to use chainer 1.18.0.
And I copied CuDNN files to some folders in “\NVIDIA GPU Computing Toolkit”.

python -c “import chainer”
python -c “import cupy”
In spite of there was no problem with this command,

python -c “import cupy.cudnn”
that command didn’t succeed ,and I got this massage.

File “”, line 1, in
File “C:\Users\MyNAME\Anaconda2\lib\site-packages\cupy\”, line 10, in
from cupy.cuda import cudnn
ImportError: cannot import name cudnn

I tried using “pip install chainer” after “pip uninstall chainer”,but I cannot solve it.

Please teach me how to solve this problem.
