python - OSError: [Errno 2] No such file or directory using pytesser

Question

This is my problem, I want to use pytesser to get a picture's contents. My operating system is Mac OS 10.11, and I have already installed PIL, pytesser, tesseract-ocr engine, and other supporting libraries like libpng and so on. But when I run my code, as below, error occurs.

from pytesser import *
import os
image = Image.open('/Users/Grant/Desktop/1.png')
text = image_to_string(image)
print text

Next is the error message

Traceback (most recent call last):
File "/Users/Grant/Documents/workspace/image_test/image_test.py",    line 10, in <module>
text = image_to_string(im)
File   "/Users/Grant/Documents/workspace/image_test/pytesser/pytesser.py", line   30, in image_to_string

File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1335, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

Besides, tesseract-ocr engine runs well on my Mac, I can run it in terminal and get the result. Below is the test picture result. tesseract result

Can anyone help me with this question,please?

Answer 1

Luckily, I solved this one.

At first, I run the command

pip install pytesseract

to install the package.

But I get the error message of 'No such file or directory using pytesser'.

Then I read this link: image_to_string doesn't work in Mac So, just run the following script:

brew link libtiff 
brew link libpng 
brew link jpeg
brew install tesseract

Worked for me ~
