The older functions like skflow.TensorFlowDNNClassifier had methods .save and .restore. These were supposedly migrated over to the contrib.learn functions, but there are no longer save and restore methods that I can find. Is there a new protocol for saving the graph and variables with the new contrib.learn package?


@ispirmustafa Could you take a look at this please?

Hi, any news on this? , im having hard times trying to save a DNNClassifier , followed some examples using train.Saver() but it says (No variables to save)


@ispirmustafa any thoughts? Assigning @martinwicke since @ispirmustafa is not in the TensorFlow org.


Checkpoints are saved automatically, and if you specify the same directory when you create another Estimator (of the same kind/same parameters), it will load the checkpoints and you can continue training.

There is currently a bug which prevents you from using the restored Estimator for inference without running at least one step of training.

I will close this issue -- for detailed questions, please ask on StackOverflow, we can track questions and answers better over there.
