Model config 준비

• 기본적인 template은 ./models참조
• 사용하고자 하는 Model에 맞춰서 config값 수정
  • 모듈에 따라 hyper-parameter값이 다양해지기 때문에 해당 모듈의 code를 참조하여 수정 할 것을 권장

Data config 준비

• 기본적인 template은 ./datasets 참조
• 사용하고자 하는 Dataset에 맞춰서 config값 수정
  • workers_per_gpu (int) : dataloader work 갯수
  • batch_size_per_gpu (int): GPU당 batch size
  • img_size (int): 모델의 image size (img_size, img_size) → 추후 업데이트 예정
  • train, val, test (dict): 각 dataset의 config
    • type: dataset의 type
    • data_root: data의 root path
    • ann: annotation 파일의 path
    • augmentation: data augmentation세팅
      • CV2 모듈들이 먼저 적용되고 pytorch(torchvision) 모듈 적용됨
      • top down 순서대로 적용

지원 하는 package Tools
