既载入模型结构(Graph)，也载入参数值
import tensorflow as tf
# importing graph
saver = tf.train.import_meta_graph("/home/jagger/workspace/tmp/model.ckpt.meta")
with tf.Session() as sess:
# loading variable value to sess
saver.restore(sess, "/home/jagger/workspace/tmp/model.ckpt")
result = tf.get_default_graph().get_tensor_by_name("add:0")
print(sess.run(result))
