Configure Theano in Windows 8.1
1. Install CUDA Toolkit:
CUDA 6.5: https://developer.nvidia.com/cuda-toolkit-65
Choose Windows 8.1 Desktop 64-bit EXE
2. Install Python and Theano related packages:
Install Anaconda: https://www.continuum.io/downloads#_windows
Choose Python 2.7 64-bit version.
3. Anaconda may not include MinGW package, install manually using Conda if nessesary:
Script: conda install -c https://conda.anaconda.org/anaconda mingw
4. Install Theano using PIP
Script: pip install theano
5. Check using test script:
import theano.tensor as T
from theano import function
x = T.dscalar('x')
y = T.dscalar('y')
z = x + y
f = function([x,y],z)
print f(2,3)
If error like 'undefined reference to `__imp__Py_TrueStruct' occured, consider: https://github.com/Theano/Theano/issues/2867
Execute:
gendef python27.dll
dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libpython27.a --input-def python27.def
Copy libpython27.a to Anaconda\libs
Extra: configurarion file for Theano:
create .theanorc.txt file under C:\Users\UserName\

Just in case you want to install Keras:
Update Theano: pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git
