Describe the problem

I am trying to train a SSD_mobilenet object detection model with Tensorflow object detection API. I have cloned the latest version and convert my dataset to tfrecord as the sample provided. Also I used sample config file and just changed the num_classes, fine_tune_checkpoint and path to train and test record.
after I run model_main.py after a few iterations the program stops with this error:
Traceback (most recent call last):
