Question

I got following error when exciting this function, error: OpenCV(4.5.2) C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-1bq9o88m\opencv\modules\imgproc\src\resize.cpp:4051: error: (-215:Assertion failed) !ssize.empty() in function 'cv::resize

for img in os.listdir(folder):
    img_path = os.path.join(folder, img)
    img_arr  = cv2.resize(cv2.imread(img_path), (IMG_SIZE, IMG_SIZE))

Answer 1

What is the shape of you input images and what are the minimum and maximum pixel values. It appears cv2.imread is not reading the image. Try using debug code below:

for img in os.listdir(folder):
    img_path = os.path.join(folder, img)
    print (img_path)
    try:
        input_img=cv2.imread(img_path)
        img_shape=input_img.shape
        print ( img_shape)
    except:
        print(' image was not read in')
