[Question] Error opening log file error

[LimHyungTae]

Is it normal that the dpgo window showed red errors before detecting loop closures?

Because I'm still on the debugging.

Since at first when I run the Kimera-Multi, I got imprecise multi-session results as follows:

So now, I speeded down the rate and re-run the code.

fyi - each kimera_vio_ros/optimized_trajectory looks fine.

For the log file error, it most likely means the log_dir_path is set to a directory that doesn't exist in the file system.

For the trajectory results, is the visualized trajectory published by dpgo_ros or kimera_distributed? Reducing the rosbag replay rate is a good idea for debugging.

@LimHyungTae has this been resolved?
