参考window下启动tensorboard

import tensorflow as tf  
with tf.name_scope('input1'):  
    input1 = tf.constant([1.0,2.0,3.0],name="input1")  
with tf.name_scope('input2'):  
    input2 = tf.Variable(tf.random_uniform([3]),name="input2")  
output = tf.add_n([input1,input2],name="add")  
writer = tf.summary.FileWriter("D://log",tf.get_default_graph())  
writer.close()

运行后会在D盘下新建log文件夹。打开cmd，输入“tensorboard --logdir=D://log”，得到网址，在浏览器中输入该网址，进入TensorBoard界面。

遇到的问题：1）代码为

writer = tf.summary.FileWriter("D://log",tf.get_default_graph()

时可显示图，但原来为

writer = tf.summary.FileWriter("/path/to/log",tf.get_default_graph())

简易版，参考tensorboard

import tensorflow as tf
a=tf.constant(2)
b=tf.constant(3)
x=tf.add(a,b)
with tf.Session() as sess:
    writer=tf.summary.FileWriter('./graphs',sess.graph)
    print(sess.run(x))
writer.close()

命令行下输入

python [yourprogram].py

tensorboard --logdir="./graphs" --port 6006
