     其中，`OPENCV_DIR`为opencv编译安装的地址；`LIB_DIR`为下载(`paddle_inference`文件夹)或者编译生成的Paddle预测库地址(`build/paddle_inference_install_dir`文件夹)；`CUDA_LIB_DIR`为cuda库文件地址，在docker中为`/usr/local/cuda/lib64`；`CUDNN_LIB_DIR`为cudnn库文件地址，在docker中为`/usr/lib/x86_64-linux-gnu/`。**注意：以上路径都写绝对路径，不要写相对路径。**

     Among them, `OPENCV_DIR` is the address where opencv is compiled and installed; `LIB_DIR` is the download (`paddle_inference` folder) or compiled Paddle prediction library address (`build/paddle_inference_install_dir` folder); `CUDA_LIB_DIR` is the cuda library file address , In docker, it is `/usr/local/cuda/lib64`; `CUDNN_LIB_DIR` is the address of the cudnn library file, in docker it is `/usr/lib/x86_64-linux-gnu/`. **Note: The above paths are written as absolute paths, do not write relative paths. **
