tensorflow的安装

1. binary安装(推荐)

注意需要能访问外网

Install pip (or pip3 for python3) if it is not already installed:

# Ubuntu/Linux 64-bit
$ sudo apt-get install python-pip python-dev

# Mac OS X
$ sudo easy_install pip

Install TensorFlow:

# Ubuntu/Linux 64-bit, CPU only:
$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.7.0-py2-none-linux_x86_64.whl

# Ubuntu/Linux 64-bit, GPU enabled:
$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.7.0-py2-none-linux_x86_64.whl

# Mac OS X, CPU only:
$ sudo easy_install --upgrade six
$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.7.0-py2-no

1. 源代码安装

   注意也是需要能访问外网，bazel编译tensorflow时候也需要访问外网

   2.1 下载最新的bazel(tensorflow采用bazel进行编译)

   https://github.com/bazelbuild/bazel/releases

   https://github.com/bazelbuild/bazel/releases/download/0.1.5/bazel-0.1.5-installer-linux-x86_64.sh

   2.2 下载最新的tensorflow代码

   git clone --recurse-submodules https://github.com/tensorflow/tensorflow

   一些编译依赖的python库安装(wheel安装.whl需要)

   $ sudo apt-get install python-numpy swig python-dev wheel

   cd tensorflow

   #CPU版本

   $ bazel build -c opt //tensorflow/tools/pip_package:build_pip_package

   #GPU版本

   $bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package

   编译大概需要10-15分钟

   #生成binary安装的whl

   $rm -rf /tmp/tensorflow_pkg

   $ ./bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg

   # The name of the .whl file will depend on your platform.
   $ sudo pip install /tmp/tensorflow_pkg/tensorflow*.whl

   cd ..

   ipython:

   import tensorflow as tf

   print tf.__version__

   另外在 https://www.tensorflow.org/versions/r0.7/get_started/os_setup.html>介绍了 使用 Virtualenv install 以及 Docker install

2. 如果是GPU机器建议可以直接pip install 一个GPU版本，然后用virtualevn安装一个CPU版本，这样方便对比实验。
