OP mentioned in a comment that he's using Python 3.6.4, so PIL won't actually help him, and I'm guessing that he'll need a Python 3 alternative.Daniel Li– Daniel Li2018-04-17 00:14:50 +00:00Commented Apr 17, 2018 at 0:14

@ZeBirdeh Hopefully he's going to incorporate that information into the post because, as it stands, the question needs work.chb– chb2018-04-17 00:49:41 +00:00Commented Apr 17, 2018 at 0:49

You should take a look at the openCV library.
import cv2
img = cv2.imread('image.jpg', flags=cv2.IMREAD_COLOR)

ModuleNotFoundError: No module named 'cv2' || I can't use cv2, there is no option to import it. I have Python3.6.4

You should install the opencv module first for this to work. pypi.org/project/opencv-python
You can use the python library: PIL & numpy. Click here to learn more about image handling in python.
import numpy
import PIL
img = PIL.Image.open("foo.jpg").convert("L")
imgarr = numpy.array(img)

- You can use this code to convert your image to array
# Import the necessary libraries
from PIL import Image
from numpy import asarray
# load the image and convert into
# numpy array
img = Image.open('test.jpg')
arraydata = asarray(img)
# data
print(arraydata)
