🔒 "Error" when i'm creating a .exe file

[opaque patrol]

python 2.7 because of dependence

i have a basic code that list my scanners and its working when i execute on my pc: py ws.py
but when i create a .exe file of this code, doenst give any error apparently, but doesnt list the devices. I'm creating the .exe file with this: py -m PyInstaller --onefile .\ws1.py

-- coding: utf-8 --

import twain

try:
src_manager = twain.SourceManager(0)
devices = src_manager.GetSourceList()
print("Aqui4", devices)
except ValueError:
print(ValueError)

When i execute the code local, it gives me
Qt: Untested Windows version 6.2 detected!
('Aqui4', ['TWAIN2 FreeImage Software Scanner'])

When i execute the code from .exe it gives me (this qt Untested Windows... doenst print)
('Aqui4', [])

• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

Are you sure you want to use twain? It's from 2010

!pip opencv-python

opencv-python v4.9.0.80

Wrapper package for OpenCV python bindings.

Released on <t:1704029648:D>.

And it's actually open source.

import cv2

index = 0
arr = []
while True:
    cap = cv2.VideoCapture(index)
    if not cap.read()[0]:
        break
    else:
        arr.append(index)
    cap.release()
    index += 1

print(arr)

Can i scan a document with this?

[opaque patrol]

i'm using because my boss sent me a project for this that uses twain, and i was triyng to execute, i'm dont code at python, learning just for this

[tall cairn]

If you're learning then you shouldn't learn something outdated.

This might help. https://pyimagesearch.com/2021/10/27/automatically-ocring-receipts-and-scans/

I agree, i was just triyng to run some code that uses this twain

[tall cairn]

Do you need to pyinstaller it?

[opaque patrol]

Probably something like this, because it is a communication between a site and the user machine to scan a document

The solution that i found was to create a websocket to install on client side and then communicate with the website
