首页 / 操作系统 / Linux / Ubuntu 15.04下TensorFlow源代码方式安装

本文介绍TensorFlow源代码方式安装。安装的系统为 Ubuntu 15.04。

获取TensorFlow源代码

1git clone --recurse-submodules https://github.com/tensorflow/tensorflow
使用 --recurse-submodules 选项来获取 TensorFlow 需要依赖的 protobuf 库文件。

安装 Bazel

遵从以下 指令 来安装 bazel 依赖。bazel 安装文件:下载地址 bazel 缺省需要使用JDK1.8,如你使用JDK1.7,请下载相应的安装包。 安装 Bazel 其他所需依赖:
1sudo apt-get install pkg-config zip g++ zlib1g-dev unzip
执行如下命令来安装Bazel:
12chmod +x PATH_TO_INSTALL.SH./PATH_TO_INSTALL.SH --user
  记住把 PATH_TO_INSTALL.SH 替换为你下载的Bazel安装文件名,如:
1./bazel-0.1.4-installer-linux-x86_64.sh  --user

安装其他依赖

1sudo apt-get install python-numpy swig python-dev

配置安装

运行 tensorflow 根目录下的 configure 脚本。这个脚本会要求你输入 python 解释器的安装路径,并允许你可选择安装CUDA库。 如果不安装CUDA,则这一步主要是定位python和numpy头文件所在位置:
12./configurePlease specify the location of python. [Default is /usr/bin/python]:
  如果要安装CUDA,则除了指定 python 外,还需指定 CUDA 安装位置:
12345678910111213141516./configurePlease specify the location of python. [Default is /usr/bin/python]:Do you wish to build TensorFlow with GPU support? [y/N] yGPU support will be enabled for TensorFlow Please specify the location where CUDA 7.0 toolkit is installed. Refer toREADME.md for more details. [default is: /usr/local/cuda]: /usr/local/cuda Please specify the location where the cuDNN v2 library is installed. Refer toREADME.md for more details. [default is: /usr/local/cuda]: /usr/local/cuda Setting up Cuda includeSetting up Cuda lib64Setting up Cuda binSetting up Cuda nvvmConfiguration finished

构建支持GPU的Tensorflow 

在tensorflow 根目录下执行如下命令:$ bazel build -c opt --config=cuda --spawn_strategy=standalone //tensorflow/cc:tutorials_example_trainer$ bazel-bin/tensorflow/cc/tutorials_example_trainer --use_gpu# Lots of output. This tutorial iteratively calculates the major eigenvalue of# a 2x2 matrix, on GPU. The last few lines look like this.000009/000005 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]000006/000001 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]000009/000009 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]Note that "--config=cuda" is needed to enable the GPU support.更多Ubuntu相关信息见Ubuntu 专题页面 http://www.linuxidc.com/topicnews.aspx?tid=2本文永久更新链接地址
