Issue Description

My code snippet

import numpy as np import argparse import cv2

print("[INFO] loading model...") net = cv2.dnn.readNetFromCaffe('pk.prototxt.txt','sd.caffemodel')

image = cv2.imread('f7.jpg')

(h, w) = image.shape[:2] blob = cv2.dnn.blobFromImage(cv2.resize(image, (300,300)), 1.0, (300,300), (104.0, 177.0, 123.0)) net.setInput(blob) detections = net.forward()

for i in range(0, detections.shape[2]):

extract the confidence (i.e., probability) associated with the

# prediction
confidence = detections[0, 0, i, 2]

if confidence > 0.5:
    box = detections[0, 0, i, 3:7] * np.array([w, h, w, h])
    (startX, startY, endX, endY) = box.astype("int")
    text = "{:.2f}%".format(confidence * 100)
    y = startY - 10 if startY - 10 > 10 else startY + 10
    cv2.rectangle(image, (startX, startY), (endX, endY),
        (0, 0, 255), 2)
    cv2.putText(image, text, (startX, y),
        cv2.FONT_HERSHEY_SIMPLEX, 0.45, (0, 0, 255), 2)

cv2.imshow("Output", image) cv2.waitKey(0)

I am getting this error OpenCV(3.4.2) C:\Miniconda3\conda-bld\opencv-suite_1534379934306\work\modules\dnn\src\layers\convolution_layer.cpp:212: error: (-215:Assertion failed) blobs.size() != 0 in function 'cv::dnn::ConvolutionLayerImpl::getMemoryShapes'

Please help its very urgent and important

There was a case on this forum with OpenCV DNN in 2018 that had a very similar error. The link below contains the advice that was given by a member of the support team.

I also faced this problem and i solved this problem by

Downloading the .caffemodel and .prototxt file from MobileNet-SSD-master repository. The file name on this repository is different so you will first rename these files according to the files you already have in your build folder. Then replace the downloaded files in your build folder. Hope it helps
