tensorflow 加载部分变量的实例讲解

import tensorflow as tf
 
v1= tf.Variable(tf.random_normal([784, 200], stddev=0.35), name="v1")
v2= tf.Variable(tf.zeros([200]), name="v2")
saver = tf.train.Saver()
with tf.Session() as sess:
 init_op = tf.global_variables_initializer()
 sess.run(init_op)
 saver.save(sess,"checkpoint/model_test",global_step=1)
