A question about convert_fer2013_to_images_and_landmarks.py

[YanGuangyou]

hello,prof!
when I run convert_fer2013_to_images_and_landmarks.py, and I want to save images,so I make --jpg=yes,but the images are not enough,for example,in PrivateTest folder,the number of images only 8.
This is my command.
python convert_fer2013_to_images_and_landmarks.py --jpg=yes --landmarks=yes --hog=yes --hog_windows=yes --hog_images=yes --onehot=yes --expressions=0,1,2,3,4,5,6
