TensorFlow 升级之后出现：

ImportError: cannot import name 'abs'

在 GitHub 中按照如下方式进行卸载重装：

pip uninstall tensorflow tensorflow-gpu protobuf --yes
pip install --ignore-installed --upgrade --ignore-installed tensorflow-gpu

依然出现上述错误！！！

大家有遇到这种情况每？

哈哈，打扰了！我解决了这个问题！

  1. 运行以下命令卸载 tensorflow 和 protocl
pip uninstall tensorflow tensorflow-gou protocol --yes
  1. 重新安装 tensorflow-gpu 1.9.0
pip install tensorflow-gpu==1.9.0

最新的 1.10.0 版本学习了吗?

哈哈哈。我昨天也遇到了。卸了重装就好了。楼主优秀，自问自答～哈哈哈

问题就是 tensorflow 和 tensorflow-gpu 版本不对应，重装或升级这俩即可。
