在Ubuntu中从源码编译TensorFlow

这里展示从源码编译得TensorFlow的过程。

原版教程在github上https://github.com/tensorflow/tensorflow/blob/master/tensorflow/g3doc/get_started/os_setup.md#installing-from-sources

首先是安装构建工具Bazel（http://www.bazel.io/docs/install.html#install-on-ubuntu）

Install on Ubuntu

Install JDK 8

If you are running Ubuntu Wily (15.10), you can skip this step. But for Ubuntu Trusty (14.04 LTS) users, since OpenJDK 8 is not available on Trusty, please install Oracle JDK 8:

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
Note: You might need to sudo apt-get install software-properties-common if you don‘t have the add-apt-repository command. See here.

1. Add Bazel distribution URI as a package source (one time setup)

$ echo "deb http://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list
$ curl https://storage.googleapis.com/bazel-apt/doc/apt-key.pub.gpg | sudo apt-key add -
If you want to use the JDK 7, please replace jdk1.8 with jdk1.7 and if you want to install the testing version of Bazel, replace stable with testing.

2. Update and install Bazel

$ sudo apt-get update && sudo apt-get install bazel

Once installed, you can upgrade to newer version of Bazel with:

$ sudo apt-get upgrade bazel
