我出现了报错
Could not find 'cudnn64_7.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Note that installing cuDNN is a separate step from installing CUDA, and this DLL is often found in a different directory from the CUDA DLLs. You may install the necessary DLL by downloading cuDNN 7 from this URL: https://developer.nvidia.com/cudnn
于是到这里去下载cuDNN 7，我是要下第7版，关键看CUDA的版本
https://developer.nvidia.com/cudnn 可能要你注册登录，这点麻烦还是要忍的
最后，就可以了，辛苦你了，hhh。
可以运行了，开心到飞起！！！开始我的NN图像识别之旅。
