title: Tensorflow Object-Detection API - Early Stopping
body: <p>I work with the TF OD API and I want to use the early stop function within the offical repo. </p>
  
  <p>I found a custom code snippet (<a href="https://github.com/hongym7/early_stopping/blob/master/model_main.py" rel="nofollow noreferrer">https://github.com/hongym7/early_stopping/blob/master/model_main.py</a>) and I found another issue on Stackoverflow related to the same topic (<a href="https://stackoverflow.com/questions/56116229/tensorflow-object-detection-api-hyperparameter-tuning-grid-search">Tensorflow Object-Detection API - Hyperparameter Tuning &amp; Grid Search</a>). However, it seems like there is something missing. </p>
  
  <p>I have the same issue. I want to use the early stop function provided by Hong (see first link) but it does not work for me as well. Does anybody has a clue what is wrong? I did the same as described in scope of the Stackoverflow issue.</p>
  
  <p>Or is there a more convinient way how to implement a simple version of early stop that aborts training if no changes are detected anymore? </p>
  
  <p>Thanks</p>
