Question

我正在尝试使用 OpenCV v.3.4.3 导入我自己的预训练 Caffe Googlenet 模型，其中我运行在训练后进行 Caffe 测试使用模型部署文件，一切正常。但是，当使用图像 blob 向 OpenCv 网络（加载后）提供异常时，我得到一个异常。

OpenCv代码：

Net net = Dnn.readNetFromCaffe("deploy.prototxt","bvlc_googlenet.caffemodel");
Mat image = Imgcodecs.imread(input.getAbsolutePath(), Imgcodecs.IMREAD_COLOR);
Mat blob = Dnn.blobFromImage(image);
System.out.println(image);
System.out.println(blob);
net.setInput(blob);
Mat result = net.forward().reshape(1);

输出错误：

Mat [ 24*15*CV_8UC3, isCont=true, isSubmat=false, nativeObj=0x1bcd0740, dataAddr=0x1a9d1880 ]
Mat [ -1*-1*CV_32FC1, isCont=true, isSubmat=false, nativeObj=0x1bcd0eb0, dataAddr=0x1a4e4340 ]

我在这里解决了这个问题： https://github.com/opencv/opencv/issues/12578#issuecomment-422304736

"there is no loss3/classifier_retrain from Caffe-deploy-model.prototxt in Caffe-train-val-model.prototxt. If you tried to run this model several times in Caffe you'll get different outputs for the same input because Caffe fills missed weights randomly."
