Hi, I am configuring the computer in order to work with GPU.
Without GPU theano worked well, but when I created the .theanorc with the
recomendated flags, it changed.
First of all I will tell you my nvidia, g++ and nvcc version:

nvcc: Cuda compilation tools, release 7.5, V7.5.17
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609
As you can see I use Ubuntu 16.04
Here is my error:

WARNING (theano.sandbox.cuda): CUDA is installed, but device gpu is not
available (error: cuda unavailable)
I can not show you my .theanorc file because I created it, but now I can
see it in its path, but I can not create another .theanorc file because a
message pops out telling that that name already exists.
Thank you very much for your help.
