Tensorflow Object Detection API 源码分析之 builders/model_builder.py

# 在model_lib.py 中 通过以下方式 创建 检测模型
# detection_model_fn = functools.partial(
#      model_builder.build, model_config=model_config)
# 此文件很重要，最重要的就是 build 函数

"""A function to build a DetectionModel from configuration."""
import functools

# 导入模型各个部分，有各种feature_extractor以及其他
