Обнаружение лица OpenCv: ошибка подтверждения с использованием model.forward ()

Question

Я просматриваю среднюю страницу для обнаружения лиц, все работает нормально, пока я не дохожу до детали model.forward (), где я получаю сообщение об ошибке -215 assertionfailed

import os
import cv2
import numpy as np
import os.path




print(os.path.dirname(os.path.abspath("__file__")))
base_dir = os.path.dirname(os.path.abspath("__file__"))


prototxt_path = os.path.join(base_dir + '/modeling/deploy.prototxt')
print(prototxt_path)
caffemodel_path = os.path.join(base_dir + '/modeling/weights.caffemodel')

model = cv2.dnn.readNetFromCaffe(prototxt_path, caffemodel_path)

# Create directory 'updated_images' if it does not exist
if not os.path.exists('updated_images'):
    print("New directory created")
    os.makedirs('updated_images')

# Create directory 'faces' if it does not exist
if not os.path.exists('faces'):
    print("New directory created")
    os.makedirs('faces')


# Loop through all images and save images with marked faces
for file in os.listdir(base_dir + '/images'):
    file_name, file_extension = os.path.splitext(file)
    if (file_extension in ['.png','.jpg']):
        print("Image path: {}".format(base_dir + '/images/' + file))

#detecting faces
image = cv2.imread(base_dir + '/images/'+ "IMG_3452.jpg")

(h, w) = image.shape[:2]
print(h,w)
blob = cv2.dnn.blobFromImage(cv2.resize(image, (300, 300)), 1, (300, 300), (104, 177, 123))

model.setInput(blob)

detection = model.forward()

Это ошибка, которую я получаю, когда достигаю model.forward ()

detection = model.forward()
Traceback (most recent call last):
