'import pyzbar.pyzbar - Unable to find zbar shared library
I want to make a script for detecting and reading QR codes from photos. I would like to use PyZbar for that, but I have a problem with some errors.
I'm working in google colaboratory
!sudo apt install tesseract-ocr
!pip install pytesseract
!pip install pyzbar[scripts]
import shutil
import os
import random
import re
import cv2
import numpy as np
import pytesseract
from pytesseract import Output
%matplotlib inline
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.pylab as pylab
import glob
import pyzbar.pyzbar
from PIL import Image
this is an error I'm struggling with:
ImportError Traceback (most recent call last)
<ipython-input-25-d8758fa4db37> in <module>()
24 import glob
25 # ZBAR - Bar Code Reader is an open source software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors

/usr/local/lib/python3.6/dist-packages/pyzbar/zbar_library.py in load()

64 if not path:

66 libzbar = cdll.LoadLibrary(path)

ImportError: Unable to find zbar shared library
Thank You ind advance for your answers

Before you can !pip install pyzbar
, you need to install libzbar with this command.
!apt install libzbar0
Then, pyzbar should work.

I had the same issue working on Amazon SageMaker, these commands worked for me
# First install zbar
!sudo apt-get install libzbar-dev -y
!sudo yum install zbar-devel -y
# Then install pyzbar
!pip install pyzbar

This solved it for me on Mac:
mkdir ~/lib
ln -s $(brew --prefix zbar)/lib/libzbar.dylib ~/lib/libzbar.dylib
