### model config:
YOLOX:
  backbone: CSPDarkNet
  neck: YOLOCSPPAN
  head: YOLOXHead
  size_stride: 32
  size_range: [10, 20] # multi-scale ragne [320*320 ~ 640*640]


### reader config:
# Note: YOLOX-tiny/nano uses 416*416 for evaluation and inference.
#       And multi-scale training setting is in model config, TrainReader's operators use 640*640 as default.
