Answer 1

Quite late, but for future reference. I stumbled upon this thread trying to run an OpenBLAS test script on the CPU. It worked fine on the GPU but the CPU gives me the same errors as the OP. I tried the suggestions here, but that didn't work. Turns out that the line in .theanorc:

ldflags=-LE:\OpenBLAS-v0.2.14-Win64-int32/bin -lopenblas

shouldn't have the space after bin and before -l. So it should be:

ldflags=-LE:\OpenBLAS-v0.2.14-Win64-int32/bin-lopenblas

Now everything works. Tried it on:

Windows 10
Python 3.5
Theano 0.9
Cuda 8 (with CudaMEM and CudaDNN)
Visual Studio 2015 Community
