No checkpoint specified (save_path=None); nothing is being restored.

https://github.com/tensorflow/models/blob/master/research/object_detection/exporter_main_v2.py

The checkpoints are saved under the training folder as ckpt-X.data-00000-of-00001 and ckpt-X.index. also a train folder is generated with the tfevent file but still the error comes that No checkpoint is specified, the training went well still there's issue with idenitification of checkpoints.

No checkpoint specified (save_path=None); nothing is being restored.-> This error is displayed
Expected Behaviour:
To get this exception https://github.com/tensorflow/models/issues/8841
To get a different exception under this but this exception is found no where else.

Bu instead getting this:-
