No module named 'cupy.cudnn'

See original GitHub issue

Hi all, please help.

I installed CUDA 9.0, cuDNN 7, Chainer 3.2.0, CuPy 2.2.0, Python 3.6 on Ubuntu 16.04 LTS

but when i check print(chainer.cuda._resolution_error) in python, i got this message: No module named 'cupy.cudnn'

I also check may installed CuDNN, here the result

$ ls /usr/include/cudnn.h
/usr/include/cudnn.h

$ ls /usr/lib/x86_64-linux-gnu/libcudnn*
/usr/lib/x86_64-linux-gnu/libcudnn.so
/usr/lib/x86_64-linux-gnu/libcudnn.so.5
/usr/lib/x86_64-linux-gnu/libcudnn.so.5.1.10
/usr/lib/x86_64-linux-gnu/libcudnn.so.7
/usr/lib/x86_64-linux-gnu/libcudnn.so.7.0.5
/usr/lib/x86_64-linux-gnu/libcudnn_static.a
/usr/lib/x86_64-linux-gnu/libcudnn_static_v7.a

I also reinstall CuDNN with this in command line

$ sudo dpkg -i libcudnn7_7.0.5.15-1+cuda9.0_amd64.deb

but when i check chainer in python, i got this result:

False

What should i do?

If you install cupy-cuda** as @kmaehashi suggested, make sure unintall cupy because of name conflict. Or, if you reinstall cupy, make sure pip install cupy --no-cache-dir (don’t miss –no-cache-dir).

@kmaehashi i did pip install cupy-cuda90, and pip uninstall cupy

$ pip freeze | grep cupy
cupy-cuda90==4.2.0

when i check chainer in python, i got this result:

>>> import chainer
>>> chainer.cuda.available
True
>>> chainer.cuda.cudnn_enabled
True

But this version of cupy-pycoda90 not compatible with installed Chainer 3.2.0, i got this error message when i train my neural net model: module 'cupy.cuda.cudnn' has no attribute 'getConvolutionForwardAlgorithm'
