Then you should use pip or setuptools to install the zbarlight wrapper.
How To use ZbarLight
from PIL import Image
import zbarlight
file_path = './tests/fixtures/one_qr_code.png'
with open(file_path, 'rb') as image_file:
image = Image.open(image_file)
image.load()
converted_image = image.convert('L') # Convert image to gray scale (8 bits per pixel).
image.close()
raw = converted_image.tobytes() # Get image data.
width, height = converted_image.size # Get image size.
code = zbarlight.qr_code_scanner(raw, width, height)
