  # 若有多个输入节点, 则应使用';'进行分隔
  # -------------------------------------------------------------------------------------------------
  # the directory where reference images of model quantization are stored
  # image formats include JPEG, BMP etc.
  # should be classic application scenarios, usually 20~100 images are picked out from test datasets
  # in addition, note that input images should cover typical scenarios

  # 如果输入的图片文件尺寸和模型训练的尺寸不一致时，并且preprocess_on为true，

  # otherwise user must keep image size as that of in training in advance

# 编译器相关参数

  # 优化等级可选范围为O0~O3
  # O0不做任何优化, 编译速度最快，优化程度最低,
  # O1-O3随着优化等级提高，预期编译后的模型的执行速度会更快，但是所需编译时间也会变长。
  # 推荐用O2做最快验证
  # ----------------------------------------------------------------------------------------------------------
  # optimization level ranges between O0~O3
  # O0 indicates that no optimization will be made 
  # the faster the compilation, the lower optimization level will be
  # O1-O3: as optimization levels increase gradually, model execution, after compilation, shall become faster
  # while compilation will be prolonged
  # it is recommended to use O2 for fastest verification
