下载Inception v-3模行 观察网络模型

下面的代码是下载Incetion v-3的代码：

# coding: UTF-8
import tensorflow as tf
import os
import tarfile
import requests

# inception模型下载地址
inception_pretrain_model_url = 'http://download.tensorflow.org/models/image/imagenet/inception-2015-12-05.tgz'

# 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)

# 获取文件名，以及文件路径
filename = inception_pretrain_model_url.split('/')[-1]
filepath = os.path.join(inception_pretrain_model_dir, filename)

# 下载模型
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)

# 解压文件
tarfile.open(filepath, 'r:gz').extractall(inception_pretrain_model_dir)

# 模型结构存放文件
log_dir = 'inception_log'
if not os.path.exists(log_dir):
    os.makedirs(log_dir)

# classify_image_graph_def.pb为google训练好的模型
inception_graph_def_file = os.path.join(inception_pretrain_model_dir, 'classify_image_graph_def.pb')

with tf.Session() as sess:
    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='')
    # writer = tf.summary.FileWriter(log_dir, sess.graph)
    writer = tf.train.SummaryWriter(log_dir, sess.graph)
    writer.close()

代码中有较好的注释，我们下面看一下Inception v-3的模型
