pytesseract,WindowsError: [Error 2] The system cannot find the file specified

Question

I am new to text extraction.when i try to extract text from a png image using pytesseract as

from PIL import Image
import pytesseract
s=Image.open('d:\\test.png')
print(pytesseract.image_to_string(s))

I am getting error as Is this the problem of image(test.png).the test.png is the image of a number plate.Should i need to install anything else.

Can you seperate the Image.open() call from the image_to_string call to see where the error occurs? — tobspr, Apr 23 '16 at 16:25
What is in Line 3 - the `Image.open` call or the image_to_string_call? You need to be more precise. — tobspr, Apr 23 '16 at 16:32
@tobspr, then next entry of the traceback is in `image_to_string` so it is the tesseract that is raising an error — Tadhg McDonald-Jensen, Apr 23 '16 at 16:33
@tobspr I have edited question.Now line 4 causing Error.pytesseract.image_to_string is causing Error. — Emmanu, Apr 23 '16 at 16:35
@Ceem, it seems that pytesseract is trying to start a subprocess but the target of the subprocess (an executable file) is missing, can you try reintalling pytesseract?

according to the PyPi information there is a perquisite that you are missing:

Install google tesseract-ocr from http://code.google.com/p/tesseract-ocr/ . You must be able to invoke the tesseract command as "tesseract". If this isn't the case, for example because tesseract isn't in your PATH, you will have to change the "tesseract_cmd" variable at the top of 'tesseract.py'.

and that link redirected me to https://github.com/tesseract-ocr/tesseract

I'm frankly disappointed that the package doesn't give you a more informative message that you are missing this, anyway once you have installed the underlying tesseract command pytesseract should work correctly :)

@it worked.Thanks.I installed tesseract-ocr from https://sourceforge.net/projects/tesseract-ocr-alt/files/ — Emmanu, Apr 23 '16 at 18:02
