no sandbox.cuda

[yuval-harpaz]

Hi following the Guided Backpropagation recipe/example I had error for: if theano.sandbox.cuda.cuda_enabled because, I guess, I use newer theano / lasagne versions with CuDNN etc. I have no cuda under theano.sandbox. two solutions:

1. skip the if and use the else option: maybe_to_gpu = lambda x: x
2. use gpu with gpuarray.dnn maybe_to_gpu = theano.gpuarray.dnn.as_gpuarray_variable x = maybe_to_gpu(x,None) and then a few lines below (as above, add None as second input argument): outp = maybe_to_gpu(self.nonlinearity(inp),None) Thanks for the examples
