I was using theano (0.9.0.dev_RELEASE) with pygpu (0.6.9). If I switch to
gpuarray backend (device=cuda), RuntimeError happens 'error doing
operation: CUDNN_STATUS_INTERNAL_ERROR', but device=gpu is OK.
How to deal with it ?

Update to the dev version of Theano. We have work around many such case.

I download the latest version of theano
from https://github.com/Theano/Theano. I even tried theano-0.10.0.dev but
the same error remains.
