raise TesseractError(proc.returncode, get_errors(error_string))

I am trying to extact text from an image using the pytesseract module in Python but I keep getting an error when I execute my code below. There is a similar question that someone provided with this answer https://stackoverflow.com/a/54914105/12642523 ..... but I still get the same error. Any tips?

import pytesseract as py
from PIL import Image
cmd = py.pytesseract.tesseract_cmd =r'C:\Users\mortiz\AppData\Local\Programs\Python\Python37-32\Scripts\pytesseract.exe'
img=r"C:\Python\Images to text\databases.jpg"
py.image_to_string(img)

! apt install tesseract-ocr
! apt install libtesseract-dev

and set

pytesseract.pytesseract.tesseract_cmd = r'/usr/local/bin/pytesseract'

because tesseract is a binary installed on your computer and you need to point your pytesseract to it.

You are passing the string as image, not image. You have to change the tesseract call as:

img=r"C:\Python\Images to text\databases.jpg"
py.image_to_string(Image.open(img))

Alternately, You can use opencv to open the image. Works fine.

You can pip install opencv using.

pip install opencv-python

Once you have installed, you can read an image by

import cv2
import pytesseract
image=cv2.imread('path/to/image.jpg')
string=pytesseract.image_to_string(image)
