Tensorflow TPU 数据转换器工具示例中的 image_utils 来自哪里?

Where does image_utils come from in Tensorflow TPU data converter tool example?

我正在尝试转换图像分类数据集以用于 Cloud TPU(如 here) and in the examples that they give, there is this file (https://github.com/tensorflow/tpu/blob/master/tools/data_converter/image_classification/image_classification_data.py 所示)。第 44 行有这个导入:

import image_utils as image

我找不到这个 image_utils 的来源。非常感谢帮助。

您所指的image_utils定义为here.
