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): File "ismar-score.py", line 72, in trajectory_base_dir + '/' + seq_name) File "ismar-score.py", line 39, in select_round return ape_list.index(np.percentile(ape_list, 50, interpolation='nearest')) File "/home/cgnerds/anaconda3/envs/demo6/lib/python3.7/site-packages/numpy/lib/function_base.py", line 3707, in percentile a, q, axis, out, overwrite_input, interpolation, keepdims) File "/home/cgnerds/anaconda3/envs/demo6/lib/python3.7/site-packages/numpy/lib/function_base.py", line 3826, in _quantile_unchecked interpolation=interpolation) File "/home/cgnerds/anaconda3/envs/demo6/lib/python3.7/site-packages/numpy/lib/function_base.py", line 3405, in _ureduce r = func(a, *kwargs) File "/home/cgnerds/anaconda3/envs/demo6/lib/python3.7/site-packages/numpy/lib/function_base.py", line 3908, in _quantile_ureduce_func r = take(ap, indices, axis=axis, out=out) File "/home/cgnerds/anaconda3/envs/demo6/lib/python3.7/site-packages/numpy/core/fromnumeric.py", line 189, in take return _wrapfunc(a, 'take', indices, axis=axis, out=out, mode=mode) File "/home/cgnerds/anaconda3/envs/demo6/lib/python3.7/site-packages/numpy/core/fromnumeric.py", line 56, in _wrapfunc return getattr(obj, method)(args, **kwds) IndexError: cannot do a non-empty take from an empty axes.

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!
