ImportError: cannot import name 'cudnn'

Hi All,

I try to install Chainer (deep learning flame work, an API).

I did followind set ups;

  1. install Python3.6
    https://www.continuum.io/downloads#windows
    Anaconda3-4.2.0-Windows-x86_64.exe

  2. install CUDA8.0
    https://developer.nvidia.com/cuda-download
    cuda_8.0.44_win10_network.exe

  3. cuDNN
    https://developer.nvidia.com/cudnn
    3.1. cuDNN v5.1 Library for Windows 10
    cudnn-8.0-windows10-x64-v5.1.zip
    3.2. extracted “cuda” folder
    put 3 files under “C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0”

  4. install chainer
    pip install chainer

  5. verify the intalls
    5.1. python -c “import chainer” -> OK.
    5.2. python -c “import cupy” -> OK.
    5.3. python -c “import cupy.cudnn” -> Fail as follows;
    Traceback (most recent call last):
    File “”, line 1, in
    File “C:\Users\syouy\Anaconda3\lib\site-packages\cupy\cudnn.py”, line 10, in
    from cupy.cuda import cudnn
    ImportError: cannot import name ‘cudnn’

Does anyone know how to solve this issue?
