title: How to use saved model to resume training in google colab?
body: <p>I am trying to train a TensorFlow object detection model on a custom dataset on google colab and I have a saved model trained for 5000 steps, is it possible to use saved model to resume training? I am planning to train for another 20000 steps. I am using google colab for training and the training will take around 36 hours, so I'm planning to use checkpoint. How to store best model checkpoints and use them when session runs out?</p>
