Documentation says to use a confidence parameter, but it throws an error

Question

Edit to include code snippet.

I am developing an app with pyautogui. I want to match a region on the desktop and click it. Calling the locateOnscreen function, I pass the filename containing the image to match, along with a confidence parameter, which throws an error.

import pyautogui as pag
button_login = pag.locateOnScreen("button_login.png", confidence=0.7)

File ".\test.py", line 23, in <module>
button_login = pag.locateOnScreen("button_login.png", confidence=0.7)
...
TypeError: _locateAll_python() got an unexpected keyword argument 'confidence'

Installed version is 0.9.47. The docs refer to version 1.0.0. I can't find this version anywhere including pypi and github.

could you also pls show a little bit of your code? – TornaxO7 Sep 07 '19 at 10:33 — TornaxO7, Sep 07 '19 at 10:33

This happens because the function locateOnScreen can reach two different functions (source code):

_locateAll_opencv if cv2 / OpenCV is installed
_locateAll_python if cv2 / OpenCV cannot be found or if you are using python3 with a version of cv2 inferior to 3

And _locateAll_python doesn't handle the confidence parameter.

So you can try to install/update OpenCV if you need this feature : https://pypi.org/project/opencv-python/

pip install opencv-python

Or if you have python 2 & 3 on your system:

pip3 install opencv-python

This worked for me too. using `pip3`. – JayRizzo Apr 15 '22 at 06:28

pip install opencv-python

pyautogui uses OpenCV in the back end to calculate confidence, and therefore it needs to be installed in Python before you can use the Confidence argument. Good luck.

Hi! This seems to be what the other answer that's already been there for a while recommends. Could you maybe edit your answer to clarify how your answer is different? – Alex Waygood Sep 18 '21 at 22:13
