I am getting a file not found error for my basic python script that interprets an image as a 2d array. This is the source code

import os
from PIL import Image
import numpy as np

def image_to_array(image_path):
    # Open an image file
    with Image.open(image_path) as img:
        # Convert the image to grayscale (optional, for simplicity)
        img = img.convert('L')
        # Convert the image to a numpy array
        img_array = np.array(img)
    return img_array

def main():

    script_dir = os.path.dirname(__file__)
    image_path = os.path.join(script_dir, 'retro_Image', 'Example.jpg')  
    img_array = image_to_array(image_path)
    print(img_array)

if __name__ == '__main__':
    main()

`

I tried to use os to join the file path and have it be the correct path but it did not work
