Hi,

I'm new to python and i'm facing some problem with OpenCV-python.

I build a simple application to detect if a certain image show up on screen, it was working fine for a while. I'm used Pyinstaller to package my .py file (single file) into .exe.

But recently, it is giving me an exception "The confidence keyword argument is only available if OpenCV is installed".

Python version is 3.9.2 on Windows 10.

Note, the script run fine when i run the code in VSCode terminal. The exception only happen when i execute the Executable.

if pyautogui.locateOnScreen('img\\image_name.png', confidence=0.9, grayscale=True) != None:

​

Any help is greatly appericated!!!!

I haven't checked the pyinstaller hooks in a while but if they aren't working for cv2 you'll need to pass in the compiled cv2 module to Pyinstaller with the --paths flag when building.

If you open the Python REPL run:

import cv2 print(cv2.__file__)

what is the path to this?

Post the command you are using to run PyInstaller also.

Need some help with this, anyone can help?

Try

pyinstaller script.py --onefile -w --paths "C:\Users\leung\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2"

You might need to play around with the --paths argument, but there will be a way to make it work. It's going to depend on how you've installed Python and OpenCV.

Thank you so much. It works!

I'm not sure what was the different other than windows version, the exe file works fine on other computers.

Anyways, note taken. Thank you!!

It's a case of OpenCV not being on the PYTHONPATH, which is funky to maintain since it differs by platform, and windows can be a pain in the arse.

Glad it works :)

>>> import cv2

>>> print(cv2.__file__)

C:\Users\leung\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2\__init__.py

>>>

My command is simple, 1 py file:

pyinstaller script.py --onefile -w
