机器人平台部署yolov5报错 [image_pub_node]: Source: ./config/target.jpg not exist!

[冬日可爱]

用户您好，请详细描述您所遇到的问题，这会帮助我们快速定位问题~

yolov5在机器人平台的板端部署基本根据文章里的操作

部署时出现一下问题

可以查看一下代码中加载的图片路径查看该路径下是否存在对应图片

[冬日可爱]

查看了，路径下有图片，依旧是报这个错误

[zhuk]

运行路径下执行ls ./config/target.jpg输出是什么？

运行的是手册哪一章节里的示例，执行命令和手册一致吗？

[冬日可爱]

root@ubuntu:~# cd /opt

root@ubuntu:/opt# cd tros

root@ubuntu:/opt/tros# cd lib

root@ubuntu:/opt/tros/lib# cd dnn_node_sample/

root@ubuntu:/opt/tros/lib/dnn_node_sample# ls

config dnn_node_sample

root@ubuntu:/opt/tros/lib/dnn_node_sample# ls ./config/target.jpg

./config/target.jpg

运行的是文档YOLOV5在地平线机器人平台的部署的板端部署下的机器人平台部署，执行命令和里面运行一致。

视频为地平线机器人平台应用系列-yolov5全流程部署

[zhuk]

这里的路径和你帖子里的路径不一致

[冬日可爱]

代码里边的路径是一致的，哎，搞不懂了

[冬日可爱]

可能是我把开发板里的图片删了，再放进去别的图片就不行了

[zhuk]

贴一下完整的log，先在运行路径下执行ls ./config/target.jpg命令在运行ros2 launch dnn_node_sample hobot_dnn_node_sample.launch.py。

另外这个示例是手册的哪一章节？

[冬日可爱]

代码为TogetheROS.Bot 用户手册的第三章，

运行的是文档YOLOV5在地平线机器人平台的部署的板端部署下的机器人平台部署，执行命令和里面运行一致。视频为地平线机器人平台应用系列-yolov5全流程部署

修改了hobot_dnn_node_sample.launch.py里边的图片路径也依旧没有改变

[zhuk]

按照刚才说的第一条，贴一下完整的log吧。
