PyTesser simple usage error
ocr, python
Solution
This isn't as well documented as it could be, but if you are not on Windows you need to install the `tesseract` binary for your platform. On Ubuntu and other Debian based Linux distributions, `apt-get install tesseract-ocr`. Then you can run:
python pytesser.py
which uses the test files `phototest.tif`, `fnord.tif` and `fonts_test.png` to test the library.
Problem
I've downloaded PyTesser and extracted it. I was in the `pytesser_v0.0.1` folder and tried to run the sample usage code in the python interpreter: ``` from pytesser import * print image_file_to_string('fnord.tif') ``` and the 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` with `Python 2.7.3` can anyone help me understand this error, and what can I do to fix it ?
