AttributeError: module 'zbar' has no attribute 'ImageScanner'

Question

I try to run this code

import pyqrcode
from qrtools import qrtools
from PIL import Image
import zbar
qr = pyqrcode.create("She got two litle horns and they get me a litle bit")
qr.png("horn.png", scale=6)
qr = qrtools.QR()
scanner = zbar.Scanner()
qr.decode("horn.png")
print(qr.data)

And it says to me

AttributeError: module 'zbar' has no attribute 'ImageScanner'

Im running the latest ubuntu x64 and have all dependencies installed mayby is because im trying on python3

Can you add the output of a `pip3 freeze`? It looks like the `zbar` package on PyPI was last updated in 2009, so it's certainly possible it doesn't work under Python 3. https://pypi.org/project/zbar/ — Taylor D. Edmiston, May 26 '18 at 01:02
Just open a terminal and run these 2 commands: `pip2 freeze` and `pip3 freeze`. And also `python --version`. — Taylor D. Edmiston, May 26 '18 at 01:05
Edit: Okay it looks like you've installed the package `zbar-py` (different than the `zbar` one I mentioned above) in the Python 3 virtual environment but not the Python 2 one. But in the Python 2 one you have separately installed a different package called `zbar`. If you run your script using `python3 foo.py` do you still get the error? — Taylor D.

Okay, it looks like zbar-py installed on python 3 includes zbar (https://github.com/zplab/zbar-py/blob/master/README.md). Can you verify that your Ubuntu version includes the iconv library required by zbar-py? — Taylor D. Edmiston, May 26 '18 at 01:17
Try running `sudo apt-get install libzbar-dev` then re-running with python3. — Taylor D. Edmiston, May 26 '18 at 01:20
libzbar-dev is already the newest version (0.10+doc-10.1build2). — Ben, May 26 '18 at 01:21
Hmm. It seems like you have everything setup correctly. You might open an issue on the zbar-py library on GitHub and link them back here to see if we've missed something. — Taylor D. Edmiston, May 26 '18 at 01:23
Also try this `sudo apt-get install libc6-dev`. https://askubuntu.com/questions/898826/why-is-there-no-libiconv-package-in-ubuntu — Taylor D. Edmiston, May 26 '18 at 01:25
Hmm. That seems right. Maybe `sudo apt-get install libzbar0`. https://www.learnopencv.com/barcode-and-qr-code-scanner-using-zbar-and-opencv/ — Taylor D. Edmiston, May 26 '18 at 01:30
It looks like there's another alternative zbar PyPI wrapper package for Python 3 - `pyzbar`. Try that one instead. https://github.com/NaturalHistoryMuseum/pyzbar — Taylor D. Edmiston, May 26 '18 at 01:31
The code has run to anoter problem now Traceback (most recent call last): File "project.py", line 7, in qr = qrtools.QR() AttributeError: module 'qrtools' has no attribute 'QR' but i will check it later — Ben, May 26 '18 at 01:33

Apparently you have to use python2 and install zbar with ubuntu package manager

sudo apt-get install python-zbar

I tested it on my Ubuntu 17.10 machine and it worked with python2. Python3 doesn't seem to work though, see here, they have the same issue: Can't install zbar

Make sure you are running the right python version by typing this in the terminal:

 python --version

It has to say: Python 2.7.X where X is 14 on my machine
