calling image_to_string errs at subprocess.py about pytesser

In this version of PyTesser, the installation files must be in the same 
directory as
the script importing PyTesser.  Later versions will be more suitable for 
installing
in site-packages, or at least more explicit about usage limitations.

I get this too. 

>>> from pytesser import *
>>> import Image
>>> im=Image.open('phototest.tif')
>>> text=image_to_string(im)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/home/shemtov/afik/pyt/pytesser.py", line 31, in image_to_string
    call_tesseract(scratch_image_name, scratch_text_name_root)
  File "/home/shemtov/afik/pyt/pytesser.py", line 21, in call_tesseract
    proc = subprocess.Popen(args)
  File "/usr/local/lib/python2.4/subprocess.py", line 542, in __init__

  File "/usr/local/lib/python2.4/subprocess.py", line 975, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

The installation files are in the same directory as the script i'm trying to, 
use,
and this should be even a moot point because I'm using the interpreter and it 
isn't
working. What am I missing?

It looks like you're using *NIX.  PyTesser was developed for Windows--it might 
work
in *NIX if you substitute a native Tesseract executable, but you'll have to be
careful about filenames.

I'm on Windows 7 and having exactly the same problem. I have tried setting 
tesseract.exe to run in compatibility with earlier versions of Windows, and as 
administrator.

This is just horrible... how is this not working in Linux in Python? Have you 
never heard of os independant path's? hm...

works fine in linux as long as tesseract executable is in PATH :)
Tested on Ubuntu 10.04 and CentOS 5.4

Another one of those "Doesn't work the way it's ****ing suppose to." A quick 
"I'll have this script ready in a few minutes" turned into a "My eyes are 
strained because I'v been staring at the damn screen for the past 3 hours 
trying to solve the same problem everybody else is experiencing above me"

It doesn't seem like anybody cared enough to guide us through a problem that's 
been going around since 2007 (it's 2011 now)....

There's an easy work around for this if you're using the pytesser directory as 
a submodule (you've added an empty __init__.py file):


Change this line in pytesser.py (line 13):
    tesseract_exe_name = 'tesseract'

to this:
    tesseract_exe_name = os.path.dirname(__file__) + '/tesseract' 


That way it will look in the correct place for the executable.

The program 'tesseract' is currently not installed.  You can install it by 
typing:

sudo apt-get install tesseract-ocr

Email #17 by [email protected] was the answer for me.

I know why this happend:

because the python script use the command: tesseract, accutally like this:  
./tesseract  input-image
but you do not install "tesseract", so it told you : The system cannot find the 
file specified

details:

1. I's not the python script who "read" the words from the picture,  It's a 
command:  "tesseract"
2. why subprocess?  because, the python execute the cmd use multi-process,  the 
equal effect codes are like this: 
    os.system("tesseract  -input_pic,  -output_words ) ,

For the next person who struggles with this, open pytesser.py and the first 
line that says:

    Import Image

Change this to 

    from PIL import Image


solved my issue.
