Answer 1

I was struggling with getting theano to work on Windows 10 x64 as well, and after reading several help guides, what worked for me in the end was the following:

1. Install Intel Distribution for Python (make sure c:\intelpython27\ and c:\intelpython27\scripts are in the PATH)
2. Open a command line and do: conda install mingw libpython
3. Then do: pip install theano
4. Download the precompiled libopenblas.dll from http://sourceforge.net/projects/openblas/files/v0.2.14/ (I got OpenBLAS-v0.2.14-Win64-int32.zip)
5. Download mingw64_dll.zip as well from http://sourceforge.net/projects/openblas/files/v0.2.14/mingw64_dll.zip/download
6. extract OpenBLAS-v0.2.14-Win64-int32.zip to c:\openblas, for example
7. extract mingw64_dll.zip to c:\openblas\bin
8. Add c:\openblas\lib and c:\openblas\bin to PATH
9. Create .theanorc.txt in c:\Users\{username}

10. Put the following in .theanorc.txt:

    [global]
    floatX = float32
    device = cpu
    
    [blas]
    ldflags = -LC:\\openblas\\bin -LC:\\openblas\\lib -lopenblas
    

Hope this helps someone.
