出這種錯誤一般是直接"pip install tensorflow-gpu"的原因。直接安裝會安裝最新的版本，但是注意到裝tensorflow有2個坑。

1. 是cuda和cudnn版本的對應性問題。
2. 是cuda、cudnn和tensorflow版本的對應性問題。
   具體查看：TensorFlow對應的支持庫。這裏有對應的版本，確保自己所安裝的版本都是一一對應的。不然只能卸載重裝。
   我的電腦室cuda9餘cudnn7，安裝TensorFlow1.12，除了這種錯誤，降版本安裝就行了。降成：

pip install tensorflow-gpu==1.10.0

解決這個問題。
但然，別的版本我沒有測試，有興趣的可以試試。
