python - PyTesser simple usage error -

-

i've downloaded pytesser , extracted it.

i in pytesser_v0.0.1 folder , tried run sample usage code in python interpreter:

from pytesser import * print image_file_to_string('fnord.tif')

and output:

traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "pytesser.py", line 44, in image_file_to_string     call_tesseract(filename, scratch_text_name_root)   file "pytesser.py", line 21, in call_tesseract     proc = subprocess.popen(args)   file "/usr/lib/python2.7/subprocess.py", line 679, in __init__     errread, errwrite)   file "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child     raise child_exception oserror: [errno 2] no such file or directory

note: i'm in ubuntu 12.10 python 2.7.3

can me understand error, , can fix ?

this isn't documented be, if not on windows need install tesseract binary platform. on ubuntu , other debian based linux distributions, apt-get install tesseract-ocr. can run:

python pytesser.py

which uses test files phototest.tif, fnord.tif , fonts_test.png test library.
