running python script by php give null result on macOS

Question

so I'm trying to execute a python file version 3.9 file using php via VScode and safari browser I spent hours trying to figure out what is the problem because it keep giving me null result

here is my code on php file

I tried other python file with only print command and they worked just fine so my connection is fine but I can't figure out what is the problem

my python code is

#!/usr/bin/python3



#import the required libraries
import cv2

import joblib

from sys import exit


from sklearn.feature_extraction.text import CountVectorizer
import pandas as pd




# function to detect face from image
def face_detection(image_to_detect):
    #converting the image to grayscale since its required for eigen and fisher faces
    image_to_detect_gray = cv2.cvtColor(image_to_detect, cv2.COLOR_BGR2GRAY)
    
    # load the pretrained model for face detection
    # haarcascade is recommended for Eigenface  
    face_detection_classifier = cv2.CascadeClassifier('php/fr/models/haarcascade_frontalface_default.xml')

    
    # detect all face locations in the image using classifier
    all_face_locations = face_detection_classifier.detectMultiScale(image_to_detect_gray)
    
    # if no faces are detected
    if (len(all_face_locations) == 0):
        return None, None
    
    #splitting the tuple to get four face positions
    x,y,width,height = all_face_locations[0]
    #[0] cuz we assume we have only one face on our data set
    
    #calculating face coordinates
    face_coordinates = image_to_detect_gray[y:y+width, x:x+height]
    
   
    #for traning and testting all images should be at same size (for egien)
    face_coordinates = cv2.resize(face_coordinates,(500,500)) #we can use any number fit for us
    
    #return the face detected and face location
    return face_coordinates, all_face_locations[0] #all_face_locations[0] beacuse there is only one face in each image

names =[]
names.append("steve jobs")   
names.append("ali alramadan") 
names.append("hillary clinton")


#########load recognition model for later use ###########
face_classifier = cv2.face.EigenFaceRecognizer_create()

face_classifier.read("php/fr/models/our model.yml")

        
######## prediction ##############
#path of the image we want to test and predict 
image_to_classify = cv2.imread("php/fr/dataset/testing/load.jpg")




#make a copy of the image cuz we dont want to ruin the actual image by writing on it
image_to_classify_copy = image_to_classify.copy()

#get the face from the image
face_coordinates_classify, box_locations = face_detection(image_to_classify_copy)  

#if no faces are returned
if face_coordinates_classify is None:
    print("There are no faces in the image to classify")
    exit()
    
#if face is returned then predict the face
name_index, distance = face_classifier.predict(face_coordinates_classify) #if distance is big then there is big different between the train image and test image

name = names[name_index]
distance = abs(distance)

print(name)


#draw bounding box and text for the face detected
(x,y,w,h) = box_locations
cv2.rectangle(image_to_classify,(x,y),(x+w, y+h),(0,255,0),2)
cv2.putText(image_to_classify,name,(x,y-5),cv2.FONT_HERSHEY_PLAIN,2.5,(0,255,0),2)



#show the image in window
cv2.imshow("Prediction "+name, cv2.resize(image_to_classify, (500,500)))
cv2.waitKey(0)
cv2.destroyAllWindows()

any suggestions please?
