Error in TextDetectorCNN_create

edit

Hi experts

I am running opencv 4.1.0 Windows 10 64 bit with python 3.7.

My code is:

img = cv2.imread('C:/projects/kort/Hjerter/IMG_2383.jpg')

det = cv2.text.TextDetectorCNN_create("c:/projects/Caffe/textbox.prototxt", "c:/projects/Caffe/TextBoxes_icdar13.caffemodel")

rects, probs = det.detect(img)

But I get the following error below. Any hints?

rects, probs = det.detect(img)
Traceback (most recent call last):
