在python中导入tesseract时无法安装qhull

Question

我想从一堆以图像形式存储的表中提取数据-

导入tesseract时提示安装Qhull(按照文档http://pytesseract.readthedocs.io/en/latest/tutorials.html)

代码-

> import Image 
> from tesseract import image_to_string
> print image_to_string(Image.open('test.png')) print
> image_to_string(Image.open('test-english.jpg'), lang='eng')

我得到以下提示，但我无法正确输入目录-

Please enter the path to an existing directory where qhull should be installed: 

我试着在引号中给出目录，也通过变量，但它一直给我无效目录错误

这应该是非常直接的，但我就是不明白。

Answer 1

用pytesseract代替

pip install pytesseract

Answer 2

You Need to change some lines of codes in
C:Python27Libsite-packagestesseractvoro.py file
in line after
    # Qhull installation 
    if config_parser.has_option('qhull','install-dir'):
        _qhulldir = config_parser.get('qhull','install-dir').strip()
    else:
    # Ask user for qhull directory
##    qstr = 'Please enter the path to an existing directory where qhull should be installed: 
        qstr = 'C:/Python27/Lib/site-packages/tesseract'
    ##    _qhulldir = os.path.expanduser(raw_input(qstr).strip())
        _qhulldir = os.path.expanduser(qstr)
