从检查点Tensorflow对象检测API还原后重新初始化的参数

Question

我正在尝试在我的GPU上使用tensorflow（1.14）对象检测API来训练对象检测器。 因此，我使用tf模型动物园的预训练模型

培训配置为：

fine_tune_checkpoint: "/home/daniel/Desktop/venv/models_latest/research/object_detection/training/experiments/faster_rcnn_3/model.ckpt"
  from_detection_checkpoint: true
  num_steps: 1
  load_all_detection_checkpoint_vars: true
  fine_tune_checkpoint_type: "detection"

一旦我为一个步骤训练一个图像，这就是输出：

看起来这些参数是从检查点恢复的，但我猜“运行local_init_op”会以某种方式覆盖它们吗

此外，大的负权重意味着什么
