爬取百度图片各种狗狗的图片,使用caffe训练模型分类
tag:
selenium PhantomJS sklearn BeautifulSoup caffe
部分依赖文件见当前目录 *.py
caffe的安装等配置请自行查阅,可以先只编译一个only cpu的
1. 代理获取
爬一些提供免费代理的网站,获取到的代理要根据速度要求等check, 可扩展爬取的网站,这里只简单爬了两个,代理质量一般,也可以用 Tor不过好像也不怎么好使了

2. 狗狗分类数据获取
import SpiderBdImg
爬虫的可设置项:
- g_enable_show: 是否使用有界面浏览器还是使用PHANTOMJS
- g_enable_proxy: 浏览器的进程是否启用代理,默认不需要,下载原图一定是使用代理没有开关
- g_enable_debug: 单进程,单线程调试模式可以debug断点
- g_enable_stream: 使用流下载图片
- K_SCROLL_MOVE_DISTANCE = 200: 模拟js window下滑距离,增大提高爬取速度
- K_SCROLL_SLEEP_TIME = 3
- K_COLLECT_PROCESS_CNT = 3: 同时启动进程个数
由于使用了线程池控制max线程数,所以就算你提高K_SCROLL_MOVE_DISTANCE,K_SCROLL_SLEEP_TIME也不会有下载速度的提升, 需要修改线程池初始化现在设置了3倍代理数量,具体详看代码: with ThreadPoolExecutor(max_workers=len(self.back_proxys) * 3) as executor:
默认启动google有界面浏览器了,因为代理质量太差,所以就起了三个进程,如果要启动多个进程在乎效率,代理质量够好,要使用PHANTOMJS
n_jobs = 3
if g_enable_debug:
n_jobs = 1
parallel = Parallel(
n_jobs=n_jobs, verbose=0, pre_dispatch='2*n_jobs')
parallel(delayed(do_spider_parallel)(proxy_df, ind, search_name) for ind, search_name in enumerate(search_list))
使用selenium配合BeautifulSoup,requests爬取图片,达到目标数量或者到所有图片停止 具体请参考SpiderBdImg
SpiderBdImg.spider_bd_img([u'拉布拉多', u'哈士奇', u'金毛', u'萨摩耶', u'柯基', u'柴犬',
u'边境牧羊犬', u'比格', u'德国牧羊犬', u'杜宾', u'泰迪犬', u'博美', u'巴哥', u'牛头梗'],
use_cache=True)
makedirs ../gen/baidu/image/金毛
makedirs ../gen/baidu/image/哈士奇
makedirs ../gen/baidu/image/拉布拉多
makedirs ../gen/baidu/image/萨摩耶
makedirs ../gen/baidu/image/柯基

makedirs ../gen/baidu/image/博美
makedirs ../gen/baidu/image/巴哥
makedirs ../gen/baidu/image/牛头梗
3. 清洗数据
人工大概扫一下图片,把太过份的删了,不用太仔细,太概扫扫就完事, 这工具其实也是可以自动识别的,先自己扫扫吧
4. 数据标准化
为caffe的lmdb做准备将图片都转换成jpeg,具体参考ImgStdHelper
运行成功后所有图片为jpeg后缀名称
import ImgStdHelper
ImgStdHelper.std_img_from_root_dir('../gen/baidu/image/', 'jpg')
5. 准备训练模型
!../sh/DogType.sh
data_path = '../gen/dog_judge/data.txt'
print(open(data_path).read(400))
哈士奇/001e5dd0f5aa0959503324336f24a5ea.jpeg 1

生成数字类别对应的label文件
import pandas as pd
import numpy as np
class_map = pd.DataFrame(np.array([[1, 2, 3, 4, 5, 6], ['哈士奇', '拉布拉多', '博美', '柴犬', '德国牧羊犬', '杜宾']]).T,
columns=['class', 'name'],
index=np.arange(0, 6))
class_map.to_csv('../gen/class_map.csv', columns=class_map.columns, index=True)
生成训练、测试数据集
import TrainValSplit
TrainValSplit.train_val_split(data_path, n_folds=10)
train_path = '../gen/dog_judge/train_split.txt'
with open(train_path) as f:
print('train set len = {}'.format(len(f.readlines())))
val_path = '../gen/dog_judge/val_split.txt'
with open(val_path) as f:
print('val set len = {}'.format(len(f.readlines())))
train set len = 9628
val set len = 1066
生成lmdb
!../sh/DogLmdb.sh
生成去均值文件
!../sh/DogMean.sh
更改train_val.prototxt
见目录sh下pb/train_val.prototxt文件。
更改solver.prototxt
见目录sh下pb/solver.prototxt文件。
7. 训练模型
使用bvlc_googlenet的solver.prototxt,train_val.prototxt训练自己的数据
根据训练数据及测试数据的量修改solver.prototxt,train_val.prototxt
由于测试数据大概1000 -> batch_size=50, test_iter: 20
训练数据大概10000 -> test_interval: 1000
display: 100 snapshot: 5000(其实snapshot大点没事,反正没次crl + c结束时会生成mode), 如过需要多留几个做对比,可调小
可以把test的mirror设置true反正数据不算多
修改DogTrain.sh 中CAFEBIN=/root/caffe/build/tools/caffe为你的caffe路径
修改solver.prototxt,train_val.prototxt中所有绝对路径为你的路径,没法使用相对路径除非想对caffe路径,那样更麻烦
详情请参考solver.prototxt,train_val.prototxt
之后使用!../sh/DogTrain.sh开始训练数据,由于要打太多日志,就不在ipython中运行了,单独启个窗口来, 生成caffemodel
8. 使用生成的模型进行分类
更改deploy.prototxt
见pb/deploy.prototxt文件。
加载模型
import caffe
caffe.set_mode_cpu()
model_def = '../pb/deploy.prototxt' # 模型文件
model_weights = '../gen/dog_judge/dog_judge_train_iter_5000.caffemodel' # 训练结果
model_mean_file = '../gen/dog_judge/mean.binaryproto' # 均值文件
net = caffe.Net(model_def, model_weights, caffe.TEST)
# 均值处理
mean_blob = caffe.proto.caffe_pb2.BlobProto()
mean_blob.ParseFromString(open(model_mean_file, 'rb').read())
mean_npy = caffe.io.blobproto_to_array(mean_blob)
mu = mean_npy.mean(2).mean(2)[0]
print('mu = {}'.format(mu))
# 颜色格式处理
transformer = caffe.io.Transformer({'data': net.blobs['data'].data.shape})
transformer.set_transpose('data', (2,0,1))
transformer.set_mean('data', mu)
transformer.set_raw_scale('data', 255)
transformer.set_channel_swap('data', (2,1,0))
