I have Theano working fine on Windows 10 without GPU support. I have a new GTX 1080 and want to get Theano running on it. This requires the latest CUDA 8.0 Toolkit from NVIDIA. I have installed everything according to http://deeplearning.net/software/theano/install_windows.html allowing for some minor software version differences. Whenever I try to simply 'import theano' with GPU support enabled via .theanorc.txt I get compilation errors.
Cuda 8.0 can work fine with Theano-master according to this thread: https://github.com/Theano/Theano/issues/4558
Running WinPython 64bit 2.7.10.3, scipy 0.161, numpy 1.9.3, Microsoft Visual Studio 12.0 and theano-master from June 16.
Latest attempt results in this list of errors:
