i'm kinda new in python and i wanna know why i can't run this cloud function in my self-hosted appwrite cloud function.
this is my code for image processing, it works on locale runs but i don't know how to make it work on cloud.

import cv2
import dlib
import numpy as np
import pytesseract
from PIL import Image


# Load the detector
detector = dlib.get_frontal_face_detector()

def extract_face(image_path, output_path, padding=35):
    # Load the image
    img = cv2.imread(image_path)
    # Convert to grayscale
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    # Use the detector to find faces
    faces = detector(gray)
    for i, face in enumerate(faces):
        # Extract the face with some padding to make the image larger
        x1, y1, x2, y2 = face.left() - padding, face.top() - padding, face.right() + padding, face.bottom() + padding
        # Ensure the coordinates are within the image boundaries
        x1, y1 = max(0, x1), max(0, y1)
        x2, y2 = min(img.shape[1]-1, x2), min(img.shape[0]-1, y2)
        # Crop the face out of the image
        crop = img[y1:y2, x1:x2]
        return crop

In the console in the appwrite self-host it logs
Docker Error: tar: short read

Summary

Developers are facing issues running a cloud function in self-hosted Appwrite. The issue might be due to an error in the Docker build process. The provided code for image processing seems to work in local runs but not on the cloud. Check the Docker logs for errors like "tar: short read" which could be causing the problem.

also part 2 of the code:

def passportProcessing(image_path):
   # Reading the image
    img = cv2.imread(image_path)

    # Convert to gray scale
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

    # Adaptive thresholding
    adaptive_thresh = cv2.adaptiveThreshold(gray, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C,
                                            cv2.THRESH_BINARY, 11, 2)

    # Morphological operations to enhance text
    kernel = np.ones((1, 1), np.uint8)
    img_morph = cv2.morphologyEx(adaptive_thresh, cv2.MORPH_OPEN, kernel)
    img_morph = cv2.morphologyEx(img_morph, cv2.MORPH_CLOSE, kernel)

    if img is not None:
        text = pytesseract.image_to_string(img_morph,lang='eng+ara')
        texts = text.split('\n')
        # Applying the cleaning function to each text and filtering out single character or empty entries
        filtered_texts_corrected = [clean_text(text) for text in texts if text.strip() and len(text.strip()) > 1]

        return filtered_texts_corrected
    else:
        print("Image not loaded correctly. Check the file path and file format: {image_path}")
        
def clean_text(text):
    return ''.join(char for char in text if char not in ('\u200f', '\u200e'))

def main(req, res):
  client = Client()
  
  print('Hello from Appwrite Function!')
  print("Variables",req.variables)

  # You can remove services you don't use
  database = Databases(client)
  users = Users(client)

  if not req.variables.get('APPWRITE_FUNCTION_ENDPOINT') or not req.variables.get('APPWRITE_FUNCTION_API_KEY'):
    print('Environment variables are not set. Function cannot use Appwrite SDK.')
  else:
    (
    client
      .set_endpoint(req.variables.get('APPWRITE_FUNCTION_ENDPOINT', None))
      .set_project(req.variables.get('APPWRITE_FUNCTION_PROJECT_ID', None))
      .set_key(req.variables.get('APPWRITE_FUNCTION_API_KEY', None))
      .set_self_signed(True)
    )
  
  return res.json({
    "areDevelopersAwesome": True,
  })

How can i run this cloud function in python.

Need support?_
