出这种错误一般是直接"pip install tensorflow-gpu"的原因。直接安装会安装最新的版本，但是注意到装tensorflow有2个坑。

1. 是cuda和cudnn版本的对应性问题。
2. 是cuda、cudnn和tensorflow版本的对应性问题。
   具体查看：TensorFlow对应的支持库。这里有对应的版本，确保自己所安装的版本都是一一对应的。不然只能卸载重装。
   我的电脑室cuda9余cudnn7，安装TensorFlow1.12，除了这种错误，降版本安装就行了。降成：

pip install tensorflow-gpu==1.10.0

解决这个问题。
但然，别的版本我没有测试，有兴趣的可以试试。
