（-215：断言失败）1 <= blobs.size（）&& blobs.size（）<= 2

Question

我正在尝试使用Caffe导入我自己的预训练的Googlenet OpenCV v.3.4.3模型，我使用模型部署文件训练后运行Caffe测试，一切正常。然而，当用图像blob喂食OpenCv网（加载之后）后，我得到一个例外。

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 ]
Exception in thread "main" CvException [org.opencv.core.CvException: cv::Exception: OpenCV(3.4.3) Z:\build tools\opencv-3.4.3\modules\dnn\src\layers\fully_connected_layer.cpp:73: error: (-215:Assertion failed) 1 <= blobs.size() && blobs.size() <= 2 in function 'cv::dnn::FullyConnectedLayerImpl::FullyConnectedLayerImpl'

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

“在Caffe-train-val-model.prototxt中没有来自Caffe-deploy-model.prototxt的loss3 / classifier_retrain。如果你试图在Caffe中多次运行这个模型，你会得到相同输入的不同输出，因为Caffe填充随机错过了重量。“
