Pose Graph doesn't converge

[Shubham-2302]

@gisbi-kim
When I am using aloam_velodyne_HDL-64.launch file the odometry is working great but I am getting this warning message

After the mini-kitti-publisher is done publishing the points the I recieve the optimized_poses.txt file but this is the output on my terminal and this doesn't converge even after leaving it for more than half an hour.

I am using Ros Melodic on VMware. Can you recommend what should I do ?

Let me know if you need more information.

Once again thank you for creating this repository.
