TL;DR

Bamboo is a mega-scale and information-dense dataset for classification and detection pre-training. It is built upon integrating 24 public datasets (e.g. ImagenNet, Places365, Object365, OpenImages) and added new annotations through active learning. Bamboo has 69M image classification annotations (4 times larger than ImageNet) and 32M object bounding boxes (2 times larger than Object365).

Label sytem

We provide the hierarchy for our label system at HERE. This JSON file includes the following attrubutes of each concept. We hope this information will be beneficial for your research.

We take concept/class dog as an example.

• Load JSON file

  #input
  with open('PATH-TO-JSON-FILE.json') as f:
  bamboo = json.load(f)
  print(bamboo.keys())
  

  #output
  'father2child', 'child2father', 'id2name', 'id2desc', 'id2desc_zh', 'id2name_zh'
  

• Check the id (n02084071) of the dog on HERE.
• Get the attrubutes you need.
  • Hypernyms bamboo['child2father']['n02084071']: domestic_animals, canine.
  • Hyponyms bamboo['father2child']['n02084071']: husky, griffon, shiba inu and etc.
  • Description bamboo['id2desc']['n02084071']: a member of the genus Canis (probably descended from the common wolf) that has been domesticated by man since prehistoric times; occurs in many breeds.
  • Included in which public dataset bamboo['id2state']['n02084071']['academic']: openimage, iWildCam2020, STL10, cifar10, iNat2021, ImageNet21K, coco, OpenImage, object365.

Special meta file

Downloading the whole dataset might be unnecessary for most purposes. We provide meta files based on the following dimension.

• Class-wise (e.g. dog, car, boat and etc.)
• Superclass-wise (e.g. animal, transportation, structure and etc.): HERE

How to download files from Google drives in the terminal?

• Install gdown

  pip install gdown
