无法恢复预先训练网络Tensorflow

Question

我坚持着修复与Tensorflow预训练的网络....

import tensorflow as tf 
import os 
os.environ['TF_CPP_MIN_LOG_LEVEL']='2' 

sess=tf.Session() 
saver = tf.train.import_meta_graph('./model/20170512-110547/model-20170512-110547.meta') 
saver.restore(sess,'./model/20170512-110547/') 

我想用这是训练前训练的网络人脸识别，然后想添加一些图层进行转移学习。 （我从这里下载的模型。https://github.com/davidsandberg/facenet）

当我执行上面的代码，它显示了错误，

我不明白，为什么系统无法找到预先训练数据... 并且目录结构如下

USER-NO-的MacBook-PRO：Transfer_face用户$ LS -R

./model：

Answer 1

导入.pb文件。

import tensorflow as tf 
from tensorflow.python.framework import tensor_util 

with tf.gfile.GFile('20170512-110547.pb', "rb") as f: 
    graph_def = tf.GraphDef() 
    graph_def.ParseFromString(f.read()) 

#import into default graph 
tf.import_graph_def(graph_def) 

#print some data 
wts = [n for n in graph_def.node if n.op == 'Const'] 

for n in wts: 
    print(tensor_util.MakeNdarray(n.attr['value'].tensor))

您需要使用CKPT路径” ./model/20170512-110547/model-20170512 -110547.ckpt-250000“而不是文件夹路径。
