Can't install the required tesseract.exe for pytesseract to function

Replit Help

Is it possible to use pytesseract in replit?

It requires tesseract:

But sudo isn’t allowed in replit and apt-get doesn’t run without sudo either.

import pytesseract
from pytesseract import Output
import pandas as pd

from PIL import Image
import numpy as np

img = np.array(Image.open("img20230815_15015501.jpg"))

custom_config = (
    r" -l eng --oem 1 --psm 6  -c preserve_interword_spaces=1pip install opencv-python"
)
d = pytesseract.image_to_data(img, config=custom_config, output_type=Output.DICT)
df = pd.DataFrame(d)

Hi @AaronBuchanan3 , welcome to the forums!
Can you try entering pip install pytesseract into the Shell?
Hope this helps!

Hi @AaronBuchanan3 ! Caould you also try poetry add pytesseract if my above post’s answer doesn’t work?
Thanks!

I can pip install pytesseract, but if requires tesseract.exe and a languge file to exist in the path. It is the exe that I can’t figure out how to install. Without these the pytesseract wrapper is useless. Still trying to learn this environment.

Thanks

Hi @AaronBuchanan3 ! Replit does not support .exe files. Sorry.

Thanks,

Not being able to leverage tesseract seems to be a pretty big void in the tech stack. Hopefully they will add it to the solution. Image OCR seems to be a pretty common use case for python. Back to my local environment for a while.

Is this post of any use?

Thanks! This does get me closer. I did add the

deps = [
    pkgs.tesseract
    pkgs.python310Packages.tesserocr..

to my nix file, but it still doesnt have the language file.

tesseract is a two part install, first tesseract and then the language specific file. Found tesseract per your input but still can find the -eng langugae file to put int the path
