Empty attribute_tokens in sample_annotation.json file

[chid_bot]

Hello,

I was exploring the sample_annotation.json file and found that there are some annotations without any attribute_tokens i.e “attribute_tokens” = []. Can you please let me know what these annotations are?

Thank you in advance,

Please check what classes these are from. We only have attributes for vehicles, cyclists and pedestrians. Barriers, cones etc. don’t have attributes.
