TensorFlow的安装

TensorFlow的安装方式有多种，包括Anaconda安装，方法如下：

1. 安装Anaconda

2. 创建一个叫做tensorflow的conda环境

# Python 2.7
$ conda create -n tensorflow python=2.7

3. 激活conda环境，用pip在该环境里安装TensorFlow

$ source activate tensorflow
(tensorflow)$  # Your prompt should change

# Ubuntu/Linux 64-bit, CPU only, Python 2.7:
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

# Ubuntu/Linux 64-bit, GPU enabled, Python 2.7. Requires CUDA toolkit 7.5 and CuDNN v4.
# For other versions, see "Install from sources" below.
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

# Mac OS X, CPU only:
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.8.0-py2-none-any.whl

4. conda环境激活后，就可以测试tensorflow是否安装成功了。

5. 用完tensorflow后，关闭环境。

(tensorflow)$ source deactivate

$  # Your prompt should change back

6. 再次需要使用tensorflow时，再激活环境。

$ source activate tensorflow
(tensorflow)$  # Your prompt should change.
# Run Python programs that use TensorFlow.
...
# When you are done using TensorFlow, deactivate the environment.
(tensorflow)$ source deactivate
