trying to call python function using jupyter notebook, does not acknowledge function declaration

Question

I am running a function in a Python program I am writing on Jupyter notebook.

When I try to call it does not recognize the name in the function call.

Here is the function declaration:

def object_detection_api(img_path, threshold=0.5, rect_th=3, text_size=3,text_th=3): 
     boxes, pred_cls = get_prediction(img_path, threshold) 
     # Get predictions 
     img = cv2.imread(img_path) 
      # Read image with cv2 
     img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)

etc.

Here is where I call it in the same python file, earlier in the code:

for images in os.listdir(folder_dir):

  # check if the image ends with png
 #if (images.endswith(".png")):
    #print(images)
  boxes, classes =  object_detection_api(, imagesthreshold=0.5, rect_th=3, text_size=3, text_th=3)

 print("boxes length: ", len(boxes))
 print("boxes type: ", type(boxes), " ", type(boxes))
 print("classes type: " , type(classes))

 #retrieve data from these results 

 #data.append(thisImageData)
 #thisImageData = {"quantity": 0, "area": 0}
 break

I tried to find a spelling mistake but I am just not saying it. Does not complain of the wrong arguments or wrong return types.

Error message:

NameError: name 'object_detection_api' is not defined

I don't know if I made an indent error or declaring it or messed up the scope somehow.

Try run your definition cell first to add your function to jupyter context, also, you need to check the return of object_detection_api,the call to object_detection_api within the loop has a syntax error: there is a comma before imagesthreshold=0.5 which should be part of the function arguments, try add image_path. Then run again your code
