could not create cudnn handle: CUDNN_STATUS_NOT_INITIALIZED

今天我在运行keras版本的cnn rnn classifier的时候，报了如下的错误：

totalMemory: 10.91GiB freeMemory: 10.20GiB

百思不得其解，查了很多资料都行不通，我的环境是cuda 9.0,ubuntu 16.04，然后我看到cudnn错误的地方好像跟cudnn有关，我的cuda是9.0,于是下载了一个cudnn 7.0,

tar zxvf cudnn-9.0-linux-x64-v7.tgz
sudo cp cuda/include/cudnn.h /usr/local/cuda/include
sudo cp cuda/lib64/* /usr/local/cuda/lib64

然后发现程序能够正常的运行了，我分析这可能是我在更新cuda后，忘记把cudnn也更新到7.0引起的，我这里记录下来，希望帮助到大家。
