[FIXED] OpenCV(4.1.0) error: (-215:Assertion failed)

Issue

I am following this tutorial series: https://www.youtube.com/watch?v=A4K6D_gx2Iw&list=PLQVvvaa0QuDfhTox0AjmQ6tvTgMBZBEXN&index=6

When I try to use the model outside the program by prediction it gives me the following error: error: OpenCV(4.1.0) /Users/travis/build/skvark/opencv-python/opencv/modules/imgproc/src/resize.cpp:3718: error: (-215:Assertion failed) !ssize.empty() in function 'resize'

Below the code when loading the model:

import cv2
import tensorflow as tf

CATEGORIES = ["Dog", "Cat"]
    import cv2
import tensorflow as tf

CATEGORIES = ["Dog", "Cat"]

def prepare(filepath):
    IMG_SIZE = 50
    img_array = cv2.imread(filepath, cv2.IMREAD_GRAYSCALE)
    #return img_array.reshape(-1, IMG_SIZE, IMG_SIZE, 1)

    new_array = cv2.resize(img_array, (IMG_SIZE, IMG_SIZE))
    return new_array.reshape(-1, IMG_SIZE, IMG_SIZE, 1)
#
model = tf.keras.models.load_model('iyad')
#
predication = model.predict([prepare("Dog.jpg")])

print(predication)

Solution

It tells you the size of the original image is 0, corresponding to when you read from img_array = cv2.imread(filepath, cv2.IMREAD_GRAYSCALE). Check if you do have that picture Dog.jpg loaded.
