Pretrained Model not loading

[raghavlite]

While I try to load the pretrained model, I get the following error.

E0903 21:29:51.073421 46912496399232 error_handling.py:75] Error recorded from prediction_loop: Unable to open table file ./trained_models/corefqa_trained/bert_finetune_
model_7_1800.bin: Data loss: not an sstable (bad magic number): perhaps your file is in a different file format and you need to use a different restore operator?

Can you please help
