Question

我想制作一个脚本，用于检测和读取照片中的QR码。我想为此使用PyZbar，但存在一些错误。

我在google实验室工作

!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

这是我正在努力解决的错误：

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
---> 26 import pyzbar.pyzbar
     27 # PIL - Python Imaging Library
     28 from PIL import Image

     63         path = find_library('zbar')
     64         if not path:
---> 65             raise ImportError('Unable to find zbar shared library')
     66         libzbar = cdll.LoadLibrary(path)
     67         dependencies = []

ImportError: Unable to find zbar shared library

感谢您提前提出答案

Answer 1

在!pip install pyzbar之前，您需要使用此命令安装libzbar。

!apt install libzbar0

然后，pyzbar应该可以正常工作。

导入pyzbar.pyzbar-无法找到zbar共享库
