Instalando o theano no Windows 8 com GPU ativada
Entendo que o suporte Theano ao Windows 8.1 está apenas em fase experimental, mas será que alguém teve sorte em resolver meus problemas. Dependendo da minha configuração, recebo três tipos distintos de erros. Presumo que a resolução de qualquer um dos meus erros resolva meu problema.
Instalei o Python usando o sistema WinPython de 32 bits, usando o MinGW, conforme descritoaqui. O conteúdo do meu.theanorc arquivo são os seguintes:

flags=-LC:\TheanoPython\python-2.7.6\libs
compiler_bindir=C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\
[blas]

Quando eu corroimport theano o erro é o seguinte:
nvcc fatal : nvcc cannot find a supported version of Microsoft Visual Studio.
Only the versions 2010, 2012, and 2013 are supported

No último erro, várias janelas pop-up perguntam como eu gostaria de abrir o arquivo (.res) antes que o erro seja gerado.
cl.exe está presente nas duas pastas (ou seja, VS 2010 e VS 2013).
Por fim, se eu definir o VS 2013 no caminho do ambiente e definir.theanorc conteúdo da seguinte forma:

Se eu correrimport theano sem a opção GPU ativada, ele é executado sem problemas. As amostras CUDA também são executadas sem problemas.
