使用Python Tesseract从图像获取文本，但出现错误

Question

I'm attempting to use to Python Tesseract to get text fron an image on my macos desktop and am running into an error that I cannot figure out. I'm running macos High Sierra 10.3.2

My directory is set to my desktop (where the image lives) and I already specified the path to my tesseract executable.

I'm running

print(pytesseract.image_to_string(Image.open('test.png')) 

and getting the following error:

File "/Users/name/anaconda2/lib/python2.7/site-packages/pytesseract/pytesseract.py", line 140, in run_and_get_output
    run_tesseract(**kwargs)
  File "/Users/name/anaconda2/lib/python2.7/site-packages/pytesseract/pytesseract.py", line 116, in run_tesseract
    raise TesseractError(status_code, get_errors(error_string))
pytesseract.pytesseract.TesseractError: (1, u'File "/var/folders/cp/dg2snlxn2631h8jx1bwb7jk80000gn/T/tess_cK4lka.PNG", line 1 SyntaxError: Non-ASCII character \'\\x89\' in file /var/folders/cp/dg2snlxn2631h8jx1bwb7jk80000gn/T/tess_cK4lka.PNG on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details')

Any idea what might be causing this and how to get around it? Would be happy to provide any clarifying details.

Thanks!

Answer 1

Seems like you are trying to render a Non-ASCII character. Try adding this to the top of your .py file to ensure UTF-8 encoding:

# -*- coding: utf-8 -*- 

As stated by the error message, see this for more details.

User the unidecode library

from unidecode import unidecode
    .
    .
    .
    print unidecode(pytesseract.image_to_string(Image.open('test.png')))
