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\
[blas] ldflags = [global] floatX = float32 device = gpu # By default the compiled files were being written to my local network drive. # Since I have limited space on this drive (on a school‘s network), # we can change the path to compile the files on the local machine. # You will have to create the directories and modify according to where you # want to install the files. # Uncomment if you want to change the default path to your own. # base_compiledir = /local-scratch/jer/theano/ [nvcc] fastmath = True flags = -LE:\Anaconda\libs compiler_bindir=C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin [gcc] cxxflags = -IE:\Anaconda\MinGW [cuda] # Set to where the cuda drivers are installed. # You might have to change this depending where your cuda driver/what version is installed.
