  • Win10 Theano Install Guide

    basic install guide

    1. download miniconda

    2. conda install libpython mingw

    3. conda install theano

    now you can run theano correctly.

    Enable GPU

    1. download and install cuda8.0

    2. downlaod and install vs2015

    2. download and install Windows Kits

    3. add path "LIB" = "C:Program Files (x86)Windows Kits10Lib10.0.14393.0umx64;C:Program Files (x86)Windows Kits10Lib10.0.14393.0ucrtx64"

        add path "INCLUDE" = "C:Program Files (x86)Windows Kits10Include10.0.14393.0ucrt";

    4. add "C:/user/your_user_name/.theanorc.txt":

    1 [global] 
    2 profile_optimizer=True
    3 profile=True
    4 floatX = float32 
    5 device = gpu 
    6 [nvcc] 
    7 compiler_bindir=D:Program Files (x86)Microsoft Visual Studio 14.0VCin
    8 [dnn]
    9 enable=auto

    5. theano gpu cpu test:

     1 from theano import function,config,shared,sandbox
     2 import theano.tensor as T 
     3 import numpy 
     4 import time
     5 print config.profile
     6 
     7 vlen=10*30*768
     8 iters=1000
     9 rng=numpy.random.RandomState(22)
    10 x=shared(numpy.asarray(rng.rand(vlen),config.floatX))
    11 f=function([],T.exp(x))
    12 print (f.maker.fgraph.toposort())
    13 t0=time.time()
    14 for i in range(iters):
    15     r=f()
    16 t1=time.time()
    17 print("loop %d time took "% iters, t1-t0,'seconds')
    18 print("results is",r)
    19 if numpy.any([isinstance(x.op,T.Elemwise) for x in f.maker.fgraph.toposort()]):
    20     print ('used the cpu')
    21 else:
    22     print ('used the gpu')
