Python module "googletrans" not working in windows system

Question

I have written a python code that translates languages from tge following input types: text, inage and audio. I am using the googletrans api for translating but it is giving htis error on running : 'NoneType' object has no attribute 'group'. But this exact same code works fine on a linux system. I used the pip package manager in both the system to install the module.

import googletrans
import pytesseract
import speech_recognition as sr
import cv2  # OpenCV for camera access

def extract_text_from_image(image):
    text = pytesseract.image_to_string(image)
    return text

def translate_text(text, target_language):
    translator = googletrans.Translator()
    translation = translator.translate(text, dest=target_language)
    return translation.text

def translate_speech(target_language):
    recognizer = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        audio = recognizer.listen(source, timeout=5)
    
    try:
        recognized_speech = recognizer.recognize_google(audio)
        translation = translate_text(recognized_speech, target_language)
        return recognized_speech, translation
    except sr.UnknownValueError:
        return None, None

def main():
    input_type = input("Enter 'text', 'image', or 'audio' for input: ").lower()
    target_language = input("Enter the target language (e.g., 'fr' for French): ").lower()
    
    if input_type == "text":
        text = input("Enter the text to translate: ")
    elif input_type == "image":
        image_path = input("Enter the path to the image: ")
        frame = cv2.imread(image_path)
        
        if frame is not None:
            # Extract text from the image
            image_text = extract_text_from_image(frame)
            if image_text:
                print("Text extracted from the image:", image_text)
                text = image_text
            else:
                print("No text found in the image.")
                return
        else:
            print("Image not found or invalid path.")
            return
    elif input_type == "audio":
        recognized_speech, translation = translate_speech(target_language)
        if recognized_speech is not None:
            print("Recognized speech:", recognized_speech)
            print("Translated speech:", translation)
        else:
            print("Could not recognize speech.")
        return
    else:
        print("Invalid input type.")
        return
    
    translated_text = translate_text(text, target_language)
    print("Translated text:")
    print(translated_text)

if __name__ == "__main__":
    main()

The following error is displayed on ruunig the above code :

Answer 1

The most likely cause of your problem here is that the search(r.text) call is returning None on the Windows box, though it's hard to be certain without seeing the code of RE_TKK. If googletrans relies on a network call (I haven't used it), it could be the Windows machine isn't configured to allow your application to issue HTTP calls, in which case it wouldn't be surprising for the search results to be empty (and you won't see what's going on if you're catching I/O exceptions without logging them.)

Answer 2

This is an issue of googletrans itself: https://github.com/ssut/py-googletrans/issues/280

As noted in the top comment:

For anyone receives NoneType' object has no attribute 'group, if you are currently using googletrans==3.0.0, please switch to googletrans==3.1.0a0 for the temporary fix.
