ubuntu/Linux下安装：

仅使用CPU:

$ pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

仅使用GPU：

$ pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl
启用GPU支持：
需要设置LD_LIBRARY_PATH 和 CUDA_HOME环境变量。
假定CUDA安装目录为usr/local/cuda，将下面两个命令添加到～/.bash_profile文件中： 

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64"

export CUDA_HOME=/usr/local/cuda

训练自己的第一个TensorFlow神经网络：
从源代码的根路径执行：

$cd tensorflow/models/image/mnist


$python convolutional.py
