lasagne isn't running on CUDA (Windows 10) .theanorc setup

[f0k]

[ProjectRoot]\Lasagne\WinPython\settings\winpython.ini was missing "THEANORC=" variable and the 'device' variable should be equal to "cuda*" but the problem mantains and the API is still unable to run from the GPU.

Theano complains that it cannot find a C++ compiler, and that pygpu is not installed. For the former, you will need to make sure that a supported compiler is on your PATH (see Theano installation instructions). For the latter, follow the libgpuarray installation instructions. The "From Zero to Lasagne" guide was written before libgpuarray/pygpu became the new and only supported backend, that's why it doesn't mention how to install it, and still uses device=gpu (old GPU backend) instead of device=cuda (new backend).

(I'm setting things up on Win10 but I can also do it on ArchLinux)

Go for Linux if you have the option. The fastest way will be to install the nvidia driver, cuda toolkit, cudnn and conda, then use conda to install Theano, Lasagne, and pygpu.
