Why do I get the error `AttributeError: module 'cv2' has no attribute 'dnn_DetectionModel' when I try to run this code:

# get the weight configurations
 configPath = 
 '/Users/Rodne/MyComputerVision/Folder3/ssd_mobilenet_v3_large_coco_2020_01_14.pbtxt'
weightsPath = '/Users/Rodne/MyComputerVision/Folder3/frozen_inference_graph.pb'

# setting the bounding box
net = cv2.dnn_DetectionModel(weightsPath, configPath)
net.setInputSize(320, 320)

Error

I have upgraded my open cv by typing this in the terminal: pip install opencv-python --upgrade and this was the result

You can also try updating the opencv module once. It worked in my case, after I updated my opencv module to opencv 4. Try running this command and see if it works:

pip install --upgrade opencv-python
