解决cuda库引用缺少文件导致的错误

1、错误

example1：

Could not load library libcudnn_ops_infer.so.8. Error: libcudnn_ops_infer.so.8: cannot open shared object file: No such file or directory
Please make sure libcudnn_ops_infer.so.8 is in your library path!

example2：

W0824 08:12:09.782843 16027 dynamic_loader.cc:267] The third-party dynamic library (libcudnn.so) that Paddle depends on is not configured correctly. (error code is libcudnn.so: cannot open shared object file: No such file or directory)

2、解决

出现该类问题，主要原因还是cuda各种库文件缺少，按照下面操作即可

（1）下载库文件

cudnn-10.1-linux-x64-v8.0.2.39.tgz

（2）解压库文件后

路径位置：/home/username/demo/cuda

 （3）设置库的路径

export LD_LIBRARY_PATH=.:/usr/local/cuda-10.2/lib64:/home/username/demo/cuda/lib64

（4）再次执行
