how to solve this issue

I can't see any useful message. Maybe you should check your configuration file. Also, you need change the output path in the configuration file.

I launch the launch file.However, I meet the problem:Failed to open configuration file.how to solve the problem?

Please show your ic_gvins.yaml.

It seems that the first configuration is wrong. outputpath: "outputpath: "/home/bobododo/GNC/SLAM/gvins_ws/src/IC-GVINS-main/output/" Maybe the correct configuration is: outputpath: "/home/bobododo/GNC/SLAM/gvins_ws/src/IC-GVINS-main/output/"
