我想使用model_main.py从头开始重新训练MSCOCO数据集上的fast-rcnn。首先，我使用带有COCO2017 Detection的create_coco_tf_record.py生成tfrecord文件，然后得到了这样的train / val文件：coco_train.record-00000-of-00100。 之后，我运行了model_main.py，并且commang窗口输出了许多警告日志。然后我被困在将0的检查点保存到/data/code/vision_ori/my_checkpoints/model.ckpt中。
我仔细检查，发现在创建新的MonitoredSession对象时进程卡住了。
