I am trying to train my custom object detection model using one of the ssd models. I got this error at the training step:

This is the command I used:
python C:\Users\user\tensorflow\model_main.py --pipeline_config_path=C:\Users\user\tensorflow\ssd_mobilenet_v2_fpnlite_640x640_coco17_tpu-8\pipeline.config --model_dir=C:\Users\user\tensorflow\workspace\training --alsologtostderr
Will be very thankful to anyone who can fix this.
