Quick Demo on KITTI

To quickly get a sense of our method's performance on the KITTI dataset, one can run the following command after installation of the code. This step does not require you to download any dataset (a small set of data is already included in this code repository).

for a demo, it's not to download any dataset.

When I want to use the quick demo code, I received the same error FileNotFoundError: [Errno 2] No such file or directory: '/home/abc/work/AB3DMOT/AB3DMOT_libs/../data/KITTI/tracking/training/oxts/0001.txt'. What should I do?

I encountered the same issue, can you explain how this problem was resolved? @Leozyc-waseda @xyllq999 @koswjjnd @cclauss @akretz

That filepath is being created here but I cannot provide further insight on how to fix this.

It appears that the issue was due to the dataset not being downloaded. Upon reading the 'kitti.md' file, I found that there were no instructions for downloading the dataset. However, the 'readme.md' file mentioned that the quick demo doesn't require downloading the dataset. Nevertheless, when running the quick demo, I couldn't find directories and files like 'data/kitti/tracking/training/oxts/*.txt'.

Thank you for your assistance. I believe I need to download the dataset and give it another try. @cclauss
