IndexError: list index out of range for synchronize_frames

[behroozbc]

I want to synchronize frames with ref to camera, but I got this error message

list index out of range
  File "/home/behro/work/uni/convertfiles/broeas-prepare-script/main.py", line 15, in <module>
    seq.synchronize_frames(ref='camera')
IndexError: list index out of range

I got this error on these datasets boreas-2020-12-04-14-00 and boreas-2021-01-26-10-59. the script

bd = BoreasDataset(pathtodset, verbose=True)
for seq in bd.sequences:
    seq.synchronize_frames(ref='camera')

This is the console message at loading datasets.

I think this error is related to the package not my script, because my script does not do anything at that moment!

I need more information to help

[behroozbc]

What information do you need? Can you give me a list?

[keenan-burnett]

I noticed you're missing radar data for the two sequences that have errors, does it work for the sequences with radar data?

I need to see the folder structure for the sequences that are giving you errors

I have problem with this datasets boreas-2020-12-04-14-00 ,boreas-2021-01-26-10-59 and boreas-2021-10-05-15-35. Now I see I think I can be related to radar dataset, I am going to download completing my datasets and send the result. my folder structure is the same as downloading with aws and I did not change anything. I run the command like this

$root=.
aws s3 sync s3://boreas/boreas-2021-04-29-15-55  $root/boreas-2021-04-29-15-55 --exclude "*"  --include "lidar/*" --include "camera/*" --include "applanix/*" --include "calib/*"

I got the command from the website download section!

Can you provide the full stack trace of your error?

[behroozbc]

I downloaded the radar dataset and the error is not showing up. It definitely related to radar dataset.

[keenan-burnett]

okay, so we can close this issue as resolved?

[behroozbc]

I found the problem, but I think it is good to fix this issue on code. Also, I found two more errors, which I will report it.

[keenan-burnett]

I'm marking this issue as resolved. Please open another issue if you find a new problem.
