I am new to VGG19 and image processing in python. I am trying to test my trained VGG19 model for predicting an image. I am getting this error:-

```
ValueError: Input 0 is incompatible with layer functional_3: expected shape=(None, 224, 224, 3), found shape=(None, 240, 240, 3)

```

My tensorflow code for predicting is:-

```
import os
os.environ['CUDA_VISIBLE_DEVICES'] = '-1'
import numpy as np
import cv2
import tensorflow as tf
from tensorflow.keras.models import load_model
model = load_model('VGG19.h5')
CATEGORIES = ["Pneumonia", "Non-Pneumonia"]
img = cv2.imread('person1_bacteria_1.jpeg')
img = cv2.resize(img,(240,240))     # resize image to match model's expected sizing
img = np.reshape(img,[1,240,240,3]) # return the image with shaping that TF wants.
prediction = model.predict(img)
prediction

```

But in the case of .ipynb file I simply get a warning regarding this:-
