tensorflow学习1

1.图的创建与选择

import tensorflow as tfg1 = tf.Graph()with g1.as_default():    v = tf.get_variable("v", [1], initializer = tf.zeros_initializer()) # 设置初始值为0g2 = tf.Graph()with g2.as_default():    v = tf.get_variable("v", [1], initializer = tf.ones_initializer())  # 设置初始值为1    with tf.Session(graph = g1) as sess:    tf.global_variables_initializer().run()    with tf.variable_scope("", reuse=True):        print(sess.run(tf.get_variable("v")))with tf.Session(graph = g2) as sess:    tf.global_variables_initializer().run()    with tf.variable_scope("", reuse=True):        print(sess.run(tf.get_variable("v")))

结果：
