我正在使用opencv_traincascade进行对象检测.我试着在照片上找到眼镜.为此,我已经下载了830张图片:http: //pi1.lmcdn.ru/product/V/I/VI060DWIHZ27_1_v2.jpg

然后,我已经下载了许多模特穿着连衣裙或只是连衣裙照片,1799张照片.

然后我用参数启动opencv_traincascade:opencv_traincascade -data Feature/classifier -vec samples.vec -bg negatives.txt -numStages 10 -minHitRate 0.999 -maxFalseAlarmRate 0.5 -numPos 830 -numNeg 1799 -w 60 -h 90 -mode ALL - precalcValBufSize 1024 -precalcIdxBufSize 1024

但是在第4步之后,我有一条消息:临时阶段的训练数据集无法填充.分支培训终止.

完整的堆栈跟踪是:

?  pictureFeature opencv_traincascade -data Feature/classifier -vec samples.vec -bg negatives.txt -numStages 10 -minHitRate 0.999 -maxFalseAlarmRate 0.5 -numPos 830 -numNeg 1799 -w 60 -h 90 -mode ALL -precalcValBufSize 1024 -precalcIdxBufSize 1024

PARAMETERS:
cascadeDirName: Feature/classifier
vecFileName: samples.vec
bgFileName: negatives.txt
numPos: 830
numNeg: 1799
numStages: 10
precalcValBufSize[Mb] : 1024 …

我想在我的django项目中创建一个auth模块.但是,当我打开我的网站url时,我有一个错误:'WSGIRequest'对象没有属性'user'

我试图找到有关此问题的信息,有人说问题出在MIDDLEWARE_CLASSES中,但我无法理解.

这是我的MIDDLEWARE_CLASSES:

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    #'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
