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

问题

I am trying to do OCR using pytesseract but getting an Windowserror. Kindly help.

from PIL import Image
from pytesseract import image_to_string
import matplotlib.pyplot as plt

Loading the images

im = Image.open('image_112472.jpg') # the second one
im.load()

Printing the text

print(image_to_string(im,lang='eng'))

I am getting the following error

Traceback (most recent call last):


 File "C:/Users/amuly/PycharmProjects/P1/Teeth_detection/test1.py", line 17, in <module>
    print(image_to_string(im,lang='eng'))

You have to make sure tesseract.exe is on your computer (for example by installing Tesseract-OCR), then add the containing folder to your PATH environment variable, or declare it's location using

import pytesseract
pytesseract.pytesseract.tesseract_cmd attribute
