本文为大家分享了TensorFLow用Saver保存和恢复变量的具体代码,供大家参考,具体内容如下 建立文件tensor_save.py,保存变量v1,v2的tensor到checkpoint files中,名称分别设置为v3,v4。 import tensorflow as tf # Create some variables. v1 = tf.Variable(3,name="v1") v2 = tf.Variable(4,name="v2") # Create model y=tf.add(v1,v2) # Add an op to initialize the variables. init_op = tf.initialize_all_variables() # Add ops to save and restore all the variables. saver = tf.train.Saver({'v3':v1,'v4':v2}) # Later,launch the model,initialize the variables,do some work,save the # variables to disk. with tf.Session() as sess: sess.run(init_op) print("v1 = ",v1.eval()) print("v2 = ",v2.eval()) # Save the variables to disk. save_path = saver.save(sess,"f:/tmp/model.ckpt") print ("Model saved in file: ",save_path) 建立文件tensor_restror.py,将checkpoint files中名称分别为v3,v4的tensor分别恢复到变量v3,v4中。 import tensorflow as tf # Create some variables. v3 = tf.Variable(0,name="v3") v4 = tf.Variable(0,name="v4") # Create model y=tf.mul(v3,v4) # Add ops to save and restore all the variables. saver = tf.train.Saver() # Later,use the saver to restore variables from disk,and # do some work with the model. with tf.Session() as sess: # Restore variables from disk. saver.restore(sess,"f:/tmp/model.ckpt") print ("Model restored.") print ("v3 = ",v3.eval()) print ("v4 = ",v4.eval()) print ("y = ",sess.run(y)) 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持编程小技巧。 您可能感兴趣的文章:
