请问这该怎么解决

Answer 1

可以尝试以下解决方案：

检查launch文件中是否有缺失的参数或者节点，检查是否有输入输出节点名称错误。

检查是否有需要启动的其他节点或者功能没有启动。

检查是否有缺失的依赖库，并确保它们已经正确安装。

检查是否有权限问题，确保程序运行时有足够的权限。

尝试重新编译程序并重新启动。

检查是否有其他程序或进程占用了所需的端口或资源。

检查是否有其他的错误信息或警告，尝试解决它们。

可以尝试查看ros服务器上的日志文件 /home/lad/.ros/log/8e05f104-94bb-11ed-b8dc-08002717c910/iris_0_ego_planner
