使用tensorflow的对象检测来训练我的模型，ckpt文件的时间戳已经超过4小时没有变化了

我在windows 10上使用anaconda(python3.6)和tensorflow(1.9.0)来训练我的模型。 我使用这个命令来训练模型: Anaconda提示符输出以下信息。

在我的模型文件夹中，ckpt文件的时间戳从未改变。 ssd_mobilenet_v1_coco中的内容。配置喜欢这个:

# SSD with Mobilenet v1 configuration for MSCOCO Dataset.
# Users should configure the fine_tune_checkpoint field in the train config as
# well as the label_map_path and input_path fields in the train_input_reader and
# eval_input_reader. Search for "PATH_TO_BE_CONFIGURED" to find the fields that
# should be configured.

为什么模型文件的时间戳没有变化?哪里出错了? 当我使用这个命令训练: 错误信息为: 问题来源StackOverflow 地址：/questions/59384999/use-object-detection-of-tensorflow-to-train-my-model-the-time-stamp-of-the-ckpt
