IndexError: cannot do a non-empty take from an empty axes.
Closed this issue · 2 comments
when I try to run my result,it seems to have some issues:
I run:python3 ismar-score.py --round 0 --is_vislam 0 --trajectory_base_dir ~/the/MY-SLAM/ --gt_base_dir ~/the/Data
and the MY-SLAM/ is just trajectory file folders
and this is the error(specific):
Traceback (most recent call last):

I need some help,where is wrong?
Maybe there is something wrong with select_round in ismar-score.py. Can you please try ./bin/accuracy at first? If this is ok, you can send trajectory folder to challenge_chairs@ismar19.org, and I will try to figure out the problem.
Currently, ismar-score.py is a prototype of overall scoring, which may not be able to handle incorrect inputs.
I just try ./accuracy. it can get some result and it seems that it has no problem.
but my pose file is wrong,the file are the poses after final global optimization,so I have to change it now.
I don't know if it will cause this issue,or just have other reasons.
I will try it again when I get right poses
thanks!
