NVIDIA deepstream 6.0 python apps 样例模型运行教程

开发硬件：NVIDIA Xavier NX developer kit ；开发软件：Jetson 4.6 ，deepstream 6.0.1

将Jetson镜像和deepstream部署到板子后，可通过deepstream官方提供的app对deepstream的运行与机制有初步了解。deepstream_python_apps下载地址于此，对这些文件的相关说明可参考第一层文件夹的README文件，或参考deepstream官网guide。

deepstream提供的python apps共有15个，每个模型的运行命令都不尽相同，需参考各自的README。

目录

运行前，请在模型所在文件夹视图，右键打开terminal（也可桌面打开然后cd到指定路径）。
