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
