I'm trying to import my own pre-trained Caffe googlenet model using OpenCV v.3.4.3, where i run a Caffe test after training using the model deploy file and everything was working fine. However when feeding the OpenCv net (after loading it) with image blob i get an exception.

OpenCv Code:

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

Output Error:

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 ]
