OSError: [WinError 193] %1 is not a valid Win32 application Python

Question

i'm trying to setup a simple OCR with python, I'm now doing tests. I use notepad++, Python 3.10.1, PIP, Pillow, pytesseract. This is my code :

import pytesseract
import numpy 
from PIL import Image, ImageEnhance, ImageFilter

pytesseract.pytesseract.tesseract_cmd = 'Lib/site-packages/pytesseract/pytesseract.py'
im = Image.open(r"C:\Users\Leonid\AppData\Local\Programs\Python\Python310\Lib\site-packages\pytesseract\test.jpg") # Ouverture du fichier image

# Filtrage (augmentation du contraste)
im = im.filter(ImageFilter.MedianFilter())
enhancer = ImageEnhance.Contrast(im)
im = enhancer.enhance(2)
im = im.convert('1')

# Lancement de la procédure de reconnaissance
text = pytesseract.image_to_string(im)
print(text)

When I execute the code, i get this error :

Traceback (most recent call last):

OSError: [WinError 193] %1 n’est pas une application Win32 valide

I tried to install numpy cause i've seen on forums that it solves the problem, and import it ("Import numpy" , line 2). But it still don't work.

What can cause this error and how to fix it?

The problem is this line:

pytesseract.pytesseract.tesseract_cmd = 'Lib/site-packages/pytesseract/pytesseract.py'

You need to set pytesseract.pytesseract.tesseract_cmd to the location of the Tesseract executable. You have instead set it to some Python script.

See this question for some examples of what this should be set to.
