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 Kits\10\Lib\10.0.14393.0\um\x64;C:\Program Files (x86)\Windows Kits\10\Lib\10.0.14393.0\ucrt\x64"

    add path "INCLUDE" = "C:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\ucrt";

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 14.0\VC\bin
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')
