某天师妹要用gpu版本的tf1.1.0 , 于是将cpu版本的tf1.1.0 卸载之：
sudo pip unintall tensorflow # 注意 我之前也是使用pip 安装的
# 所以可以这样下载， 如果是源码安装的方式 ，不应该这样卸载
但是访问tensorflow.org的时候我发现只有0.12 版本的：
what? 怎么办？
还好细心的我发现 tf的下载链接很有规律：
tf的下载链接的格式一般是：
TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/{gpu|cpu}/tensorflow_{gpu|cpu}-{版本号}-cp{35|27}-{none|cp35m|cp27m}-linux_x86_64.whl
找出了规律以后，cp35是适合于python35的tf, cp27是适合python27的链接 ； 就是一个一个的尝试了，这里比较头大的是版本号： 1.1.0rc1 是我在一个cpu 版本的连接上找到的：
于是修改成这个：
TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.1.0rc1-cp27-none-linux_x86_64.whl
安装信息如下：
sudo pip install --ignore-installed --no-cache-dir --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.2.0rc1-cp27-none-linux_x86_64.whl
