1.下载tensorflow源码：
$ git clone https://github.com/tensorflow/tensorflow
2.安装JDK
$ sudo apt-get install openjdk-8-jdk
3.安装bazel（apt）：
$ echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list
$ curl https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -
$ sudo apt-get update && sudo apt-get install bazel
安装bazel（binary installer）：
$ sudo apt-get install pkg-config zip g++zlib1g-dev unzip python
Download bazel installer: https://github.com/bazelbuild/bazel/releases
$ chmod +x bazel--installer-linux-x86_64.sh
$ ./bazel--installer-linux-x86_64.sh --user
$ vim ~/.bashrc
添加：export PATH="$PATH:$HOME/bin"
4.安装依赖库：
# for Python 2.7
$ sudo apt-get install python-numpypython-dev python-pip python-wheel
# for Python 3.x
$ sudo apt-get install python3-numpy python3-dev python3-pip python3-wheel
5.配置：
$ cd tensorflow*
$ ./configure
安装命令行提示，逐个设置编译选项（最简单的版本一路默认，选no）
6.编译：
$ bazel build --config=opt --incompatible_load_argument_is_label=false //tensorflow/tools/pip_package:build_pip_package
7.生成whl包：
$ bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
8.安装生成的包：
$ sudo pip install /tmp/tensorflow_pkg/tensorflow-*.whl
9.重启：
$ sudo reboot
备注：
遇到“The following packages have unmet dependencies:”的问题：
$ sudo apt-get clean
$ sudo apt-get autoclean
$ sudo apt-get -f install
$ sudo dpkg --configure -a
$ sudo apt-get -f install
Bazel卸载：
$ sudo apt-get --purge remove bazel
$ sudo apt autoremove
Tensorflow修改源代码后重新编译：
#!/bin/bash
sudo pip uninstall tensorflow -y
bazel build --config=opt --incompatible_load_argument_is_label=false //tensorflow/tools/pip_package:build_pip_package
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
sudo pip install /tmp/tensorflow_pkg/tensorflow-*.whl
查看tensorflow版本和路径信息：
python环境执行：
>>> import tensorflow as tf
>>> tf.__version__
输出tensorflow版本信息
>>>tf.__path__
输出tensorflow安装路径
