Failure on KITTI Dataset

[harisbinyousaf24]

Dear team members, I appreciate the work done by you guys and i am already a fan of your previous work related to lidar odometry. But the issue i am facing today is regarding lidar_visualizer:

The things is that i was trying to run bag file and it worked fine as long as frames were iterated over and over again but whenever frames ended it raised StopIteration error. Below i shared the snap shot of the error.

I wanted to know is this how it always end? i tried to debug but i couldn't find any mistake with my data. Also this is one case. Another case is when i tried to run my another bag file the visualizer opened but it was blank. (For some reasons i can't share the bag file) but i wanted to know is there specific format in which frames are interpreted for the visualizer?

Are you using the KITTI dataset or bagfiles? 🤔

@nachovizzo I actually downloaded one from this opensource link inside LIO-SAM repository (which to my understanding is KITTI data converted into bag file) and tried to visualize it. But for my own bag files I didn't see anything although input command line arguments were just fine. The lidar data comes from RSHelios 5515 lidar in my bag files.
