Errors when converting nuScenes dataset

Hello, thanks for the great work!
I'm trying to convert the nuScenes dataset, however I got several errors:
- There are scenes with velocity >50 and causing the assertion error. Is there something wrong for velocity measurement or is the velocity correct?
- I then got error of
ValueError: could not broadcast input array from shape (193,3) into shape (191,3)
at this line https://github.com/metadriverse/scenarionet/blob/e9c1419a91c42e67fe176a538d2984cf1d9e0f93/scenarionet/converter/nuscenes/utils.py#L206C13-L206C81 What's the issue of this? - How do you deal with multiprocessing's OOM error (shows "killed")?
Thanks for your time!

Hi, sorry for the late reply. I didn't watch this repo until now...
For your questions:
-
nuScenes data is actually collected in a low frequency, so I interpolate the data to make them 10hz. To make sure the interpolation won't generate some outliers, I add that some assert. Just ignore them for free.
-
Could you tell me which nuScenes split you are using? There must be something wrong in the interpolation process. It is currently tested on the nuPlan-mini only. I will fix the bugs and update the progress soon.

Lower the number of workers can solve this like 'num_workers=2'
