2. Describe the bug

I am trying to do custom object detection training using ssd_mobilenet_v2_fpnlite_640x640_coco17_tpu-8 and I downloaded the checkpoint .gz file from the model zoo. But when I checked that folder the files are as below-

But in the ssd_mobilenet_v2_fpnlite_640x640_coco17_tpu-8.config file, the name of the checkpoint is different. I am not seeing any file name as mobilenet_v2.ckpt-1 in downloaded checkpoints-

Please tell me what should be the correct value in this line as per downloaded files from the model zoo-

3. Steps to reproduce

!python object_detection/model_main_tf2.py
--pipeline_config_path={PIPELINE_CONFIG_PATH}
--model_dir={MODEL_DIR}
--alsologtostderr
