The blobFromImage function returns an abnormal result #2095

This is my code,the width and height of the blob are always -1. Mat img = opencv_imgcodecs.imread(imagePath); Mat blob = opencv_dnn.blobFromImage(img, 1.0, new Size(640, 640), new Scalar(0.0), true, false, CV_32F);

That's probably normal if the blob has 4 dimensions.
