I am trying to run neural network on chainer by GPU. but it seems to be just not working. I tried some version of cuda already, 9.0, 10.1, 10.0. Before I had some problem cupy installation. Now I am just install cupy through Anaconda environment. cuda.to_gpu and cupy.array seems to work
I have no clue about the problem now.
Exception in main training loop: module 'cupy.cudnn' has no attribute 'softmax_forward'

Will finalize trainer extensions and updater before reraising the exception.

Followed by @corochann suggestion. I have reinstall and update chainer, but now I cant install cupy. below is chainer.print_runtime_info().
