Cannot use gpu in Theano

I installed from AUR cudnn & python-theano.

But I cannot use my gpu:

$ python
In [1]: import theano
WARNING (theano.sandbox.cuda): CUDA is installed, but device gpu0 is not available  (error: Unable to get the number of gpus available: unknown error)

How can I fix this issue?

Here are some diagnostics:

$ lspci | grep -i nvidia
01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 770] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller (rev a1)

$ nvidia-smi

Re: Cannot use gpu in Theano

I've run into exactly the same issue, except for using virtualenv installed theano and not python-theano. I've also tried tensorflow with GPU and it doesn't work as well, saying CUDA is installed, but GPU is not available.

Anyone manaegd to resolve this?
