This is my code:
# loading image from folder folders = glob.glob('path to folder ') imagenames_list =  for folder in folders: for f in glob.glob(folder+'/*.jpg'): imagenames_list.append(f) read_images =  for image in imagenames_list: read_images.append(cv2.imread(image, cv2.IMREAD_GRAYSCALE)) re_size = cv2.resize(read_images, (50,50), interpolation=cv2.INTER_LINEAR)
I get this error
Expected Ptr<cv::UMat> for argument '%s'
What does this mean and how can I fix it?
