Python and JavaScript link

I was trying to link the Javascript Electron app with the python deep learning engine by using PYthon-shell. But I don't know where to go now.

This is the python code:

from keras.models import load_model
import cv2
import numpy as np
import os
from PIL import ImageTk, Image

from sklearn.preprocessing import label
import sys




model = load_model('model.h5')
model.compile(optimizer='adam', loss='binary_crossentropy',
                  metrics=['accuracy'])

img = cv2.imread('file/4/1.jpg')

img = np.reshape(img, [1, 28, 28, 3])
class1 = model.predict_classes(img)

print("the pridicted number is", class1 + 1)

sys.stdout.flush()

The javascript code looks like:

 let {PythonShell} = require('python-shell')
  var path = require('path');
function getPrediction() {
 
  
  let pyInput ={
    scriptPath : path.join('/../BackEnd/'),
    pyPaht :path.join( '/../BackEnd/')

  }


PythonShell = new PythonShell('numbers.py', pyInput);


pyshell.on('message', function(message) {
    alert(message);
  })

}

Here is the error output:

index.js:35 Uncaught ReferenceError: Cannot access 'PythonShell' before initialization
    at jsFunction

I'm pretty sure

PythonShell = new PythonShell('numbers.py', pyInput);

should read

pyshell = new PythonShell('numbers.py', pyInput);

Also you've misspelt alert as aler.
