您好，我运行roslaunch turtlebot3sim single_robot_origin.launch 时报错 *[ INFO] [1731569430.698439536]: I1114 15:30:30.000000 170794 map_builder_bridge.cc:136] Added trajectory with ID '0'.

Sorry for the problem. These lines are used for recording the experiment results. So, you can just remove all the lines that write data to your computer.

I also pushed a new version of _mappadding.py. You can pull this repository again or just change that file.

If you get any problem, do not hesitate to contact me. I am glad to see my work receive your attention.

thanks！现在可以成功运行了，但还是会报一些warn和error，对结果有影响吗

this is a not a big problem, I do not meet this problem when I was running on my computer. This problem seems to be related to the tf in ROS, and the SLAM module can lead to this problem. You can check the related part if you want to solve it.
