How to keep the trained model and how to read the generated files?

[Gu-Youngfeng]

In Tensorflow, we use object tf.train.Saver() to save the trained model, the generated files include

• checkpoint
• XX.ckpt.data-00000-of-00001
• XX.ckpt.index
• XX.ckpt.meta

Except for the first file(checkpoint), all the files cannot be opened by normal notepad. What do they mean and how can I use them?

1. How to keep the trained model?

# variables initialization
init = tf.global_variables_initializer()
# saver
saver = tf.train.Saver()
with tf.Session() as sess:
    sess.run(init)
    saver.save(sess, "models/lstm.ckpt") # save the model into lstm.ckpt

2. How to read the generated files?

saver = tf.train.import_meta_graph("models/nn.ckpt.meta")
with tf.Session() as sess:
    saver.restore(sess, "models/nn.ckpt")
    graph = tf.get_default_graph()
    ...
