トレーニングされた TensorFlow モデルを保存および復元するにはどうすればよいですか?

import tensorflow as tf

# Create a saver object to save all variables
saver = tf.train.Saver()

# Save the graph with the specified global step
saver.save(sess, 'my_test_model', global_step=1000)

import tensorflow as tf

sess = tf.Session()

# Restore graph and weights using meta graph and restore operation
saver = tf.train.import_meta_graph('my_test_model-1000.meta')
saver.restore(sess, tf.train.latest_checkpoint('./'))

# Retrieve saved variables and operations
