Deep Learning: win7安装Theano,配置GPU

1. 安装 AnacondaCE:

下载地址:http://repo.continuum.io/archive/index.html 和 http://repo.continuum.io/anaconda3/ 

我是win64,选择Anaconda-1.4.0-Windows-x86_64.exe安装

Anaconda会自动安装python.exe和theano的所有依赖项


2. 安装 Theano:

下载地址:https://github.com/Theano/Theano-wininstaller/raw/master/bin/theano_installer_latest.msi

默认安装完成之后,会在cmd的根目录下(打开cmd时显示的目录)生成一个 theanorc_default.txt文件,里面的内容为:

[global]
openmp=False

[blas]
ldflags=

为了使用GPU,我们将theanorc_default.txt文件名改为theanorc.txt,同时将其中的内容改为:

[blas]
ldflags =

[gcc]
cxxflags = -ID:\Anaconda\MinGW

[nvcc]
fastmath = True
flags=-LD:\Anaconda\libs
compiler-bindir=D:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin
base_compiledir=path_to_a_directory_without_such_characters

[global]
floatX = float32
device = gpu0


3. 配置GPU:

4. 下载DeepLearningTutorials测试代码

按照上述安装,theano里除了convolutional_mlp.py以外的所有代码都可以运行,当运行convolutional_mlp.py时出现以下错误:

ValueError: Was not able to allocate output!
WARNING (theano.gof.compilelock): Overriding existing lock by dead process '5216' (I am process '5488')
Error allocating 5760000 bytes of device memory (unknown error).

调试之后发现是theano库中function_module.py代码出现了问题,于是用自己下载的theano-mater中的theano子文件夹(【Theano-master下载】)替换掉theano_installer_latest.msi自动安装的theano(Anaconda\Lib\site-packages\theano),问题解决~~
