summary_writer.add_graph(sess.graph)#添加graph图

tf.summary.scalar('loss', loss)

tf.summary.scalar('accuracy', accuracy)

sum_ops = tf.summary.merge_all()#自动管理

metall = sess.run(sum_ops, feed_dict={X: batch_x_test, Y: batch_y_test, keep_prob: 1.})

summary_writer.add_summary(metall, global_step=step) # 写入文件
