file naming in annotations.zip

[RohitKeshari]

annotations.zip has the following files.

• train:
  • train.json
• val:
  • all_classes.json
  • common_classes.json
  • uncommon_classes.json
  • first_frame_annotations.json
• test:
  • all_classes.json
  • common_classes.json
  • uncommon_classes.json
  • first_frame_annotations.json
• info:
  • categories.json
  • class_split.json

My question is: in train, does train.json is equivalent to all_classes.json or I downloaded old or wrong annotation?
