Tensorflow: how to save/restore a model?

Question

After you train a model in Tensorflow:

1. How do you save the trained model?
2. How do you later restore this saved model?

Answer 1

Use tf.train.Saver to save a model, remerber, you need to specify the var_list, if you want to reduce the model size. The val_list can be tf.trainable_variables or tf.global_variables.
