TensorFlow(十四)：谷歌圖像識別網絡inception-v3下載與查看結構

上代碼：

import tensorflow as tf
import os
import tarfile
import requests

#inception模型下載地址
inception_pretrain_model_url = 'http://download.tensorflow.org/models/image/imagenet/inception-2015-12-05.tgz'
# inception_pretrain_model_url = 'http://download.tensorflow.org/models/inception_v4_2016_09_09.tar.gz'

#模型存放地址
inception_pretrain_model_dir = "inception_model"
if not os.path.exists(inception_pretrain_model_dir):
    os.makedirs(inception_pretrain_model_dir)
    
#獲取文件名，以及文件路徑
filename = inception_pretrain_model_url.split('/')[-1]
filepath = os.path.join(inception_pretrain_model_dir, filename)

#下載模型
if not os.path.exists(filepath):
    print("download: ", filename)
    r = requests.get(inception_pretrain_model_url, stream=True)
    with open(filepath, 'wb') as f:
        for chunk in r.iter_content(chunk_size=1024):
            if chunk:
                f.write(chunk)
print("finish: ", filename)
#解壓文件
tarfile.open(filepath, 'r:gz').extractall(inception_pretrain_model_dir)
 
#模型結構存放文件
log_dir = 'inception_log'
if not os.path.exists(log_dir):
    os.makedirs(log_dir)

#classify_image_graph_def.pb爲google訓練好的模型
inception_graph_def_file = os.path.join(inception_pretrain_model_dir, 'classify_image_graph_def.pb')
# inception_graph_def_file = os.path.join(inception_pretrain_model_dir, 'inception_v4.ckpt')
with tf.Session() as sess:
    #建立一個圖來存放google訓練好的模型
    with tf.gfile.FastGFile(inception_graph_def_file, 'rb') as f:
        graph_def = tf.GraphDef()
        graph_def.ParseFromString(f.read())
        tf.import_graph_def(graph_def, name='')
    #保存圖的結構
    writer = tf.summary.FileWriter(log_dir, sess.graph)
    writer.close()

結構：

打開cmd，進入inception_log目錄：執行：tensorboard --logdir='C:\Users\FELIX\Desktop\tensor學習\inception_log'查看結構。
