After 3 hours on a machine with 2 gpus, I reached this value

```
model_lib_v2.py:708] {
'Loss/classification_loss': 0.28390533,
'Loss/localization_loss': 0.26865262,
'Loss/regularization_loss': 57.277615,
'Loss/total_loss': 57.83017,
'learning_rate': 0.0}
```

I researched and the zero learning_rate means that there is nothing to learn, **but the train with model_main_tf2.py don’t end **

Please any help is appreciated.

Thanks
