到运行python的所在目录下,打一下命令:
$ tensorboard --logdir="logs/"
再在网页中输入链接:127.0.1.1:6006 即可获得展示: 推荐使用friefox浏览器,我电脑上chrom浏览器打不开
所以我们可以简单的写几行Pyhton,加载Graph,只在logdir里,输出Graph结构数据,并可以查看其图结构。
可参考:http://www.tensorfly.cn/tfdoc/how_tos/summaries_and_tensorboard.html
https://www.tensorflow.org/get_started/summaries_and_tensorboard
你可以在jupyter里操作,代码如下:
import tensorflow as tf
from tensorflow.python.platform import gfile
# 这是从二进制格式的pb文件加载模型
graph = tf.get_default_graph()
graphdef = graph.as_graph_def()
graphdef.ParseFromString(gfile.FastGFile("/data/TensorFlowAndroidMNIST/app/src/main/expert-graph.pb", "rb").read())
_ = tf.import_graph_def(graphdef, name="")
#这是从文件格式的meta文件加载模型
_ = tf.train.import_meta_graph("model.ckpt.meta")
summary_write = tf.summary.FileWriter("/data/TensorFlowAndroidMNIST/logdir" , graph)
然后再启动tensorboard:
tensorboard --logdir /data/TensorFlowAndroidMNIST/logdir --host 你的ip --port 你端口(默认6006)

$ tensorboard --logdir="logs/"

比如,从他人处获得一个Graph,想看看它的结构,怎么弄?
Google提供了一个工具,TensorBoard,它能以图表的方式分析你在训练过程中汇总的各种数据,其中包括Graph结构。所以我们可以简单的写几行Pyhton,加载Graph,只在logdir里,输出Graph结构数据,并可以查看其图结构。
