Tensorflow, what is saved with tf.train.Saver?
<p>I am wondering what exactly is saved when I use a tf.train.Saver() to save my model after every training epoch.  The file seems kind of large compared to what I am used to with Keras models.  Right now my RNN takes up 900 MB at each save.  Is there any way to tell the saver to only save the trainable parameters?  I would also like a way to save only part of the model.  I know I can just get the variables I define and save them using the numpy format but when I use the RNN classes I don't directly have access to their weights and I looked through the code and there is nothing like get_weights that I can see.</p>
