WinError 5 PermissionError on Windows 10

[Supharerk Thawillarp]

I'm new to tesseract and trying to follow tutorial on Windows 10 using the code below

import cv2
import pytesseract
from pytesseract import Output
pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files\\Tesseract-OCR\\tesseract.exe'


img=cv2.imread('images/invoice-sample.jpg')


d=pytesseract.image_to_data(img,output_type=Output.DICT)




print(d.keys)

The problem is, I keep getting error PermissionError: [WinError 5] Access is denied: 'from implementing image_to_data and image_to_string in Windows 10.

Only resource I found in stackoverflow is to set tesseract_cmd, PATH and TESSDATA_PREFIX which did not work for me. Not even using the administrative cmd works. 

After spending a couple hours I found setting permission for tesseract.exe (right click, select property and go to security tab) by checking Full control and Modify below to make it works.

Hope this will help some people strugglingthe same problem.

Can you replicate problem with command line /"pure" tesseract? e,g,

'C:\\Program Files\\Tesseract-OCR\\tesseract.exe'   images/invoice-sample.jpg invoice-sample

No, the tesserect successfully run with output generated in textfile.

This means there is problem with pytesseract/python permissions.

Can you get output for pytesseract.get_tesseract_version()?

Sure

1. Make sure you have the latest version of tesseract.

Then try this script and provide exact/full error message:

import tempfile

import cv2
import pytesseract
from PIL import Image

from pytesseract import Output

pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files\\Tesseract-OCR\\tesseract.exe'
img = cv2.imread('images/invoice-sample.jpg')

# check temp file
temp_file = tempfile.NamedTemporaryFile(prefix='tess_')
print(temp_file.name)
image = Image.fromarray(img)
image.save(temp_file.name + '.png', format='png', **image.info)
temp_file.close()

if img.any():
    print("Image shape:", img.shape)
    data_dict = pytesseract.image_to_data(img, output_type=Output.DICT)
    n_boxes = len(data_dict['level'])
    for i in range(n_boxes):
        (x, y, w, h) = (data_dict['left'][i], data_dict['top'][i], data_dict['width'][i], data_dict['height'][i])
        cv2.rectangle(img, (x, y), (x + w, y + h), (255, 125, 125), 2)
    cv2.imshow('img', img)
    cv2.waitKey(0)
else:
    print("Can not open input file")

Hello,

I am not able to reproduce error, errors come from here [1] where pytesseract tries to cleanup temporary files.

You should report it to pytesseract project as there is no option to skip this code.

Maybe you can try to modify this part of pytesseact code[2]:

finally:
    cleanup(f.name)

to 

finally:
    f.close()
    cleanup(f.name)

After diving in pytesseract.py I found one possible related issue in the NamedTemporaryFile.

According to the post in stackoverflow (https://stackoverflow.com/questions/55081022/python-tempfile-with-a-context-manager-on-windows-10-leads-to-permissionerror), I added the delete=False argument in the NamedTemporaryFile function in pytesseract.py.

@contextmanager

#https://stackoverflow.com/questions/55081022/python-tempfile-with-a-context-manager-on-windows-10-leads-to-permissionerror

def save(image):

    try:

        with NamedTemporaryFile(prefix='tess_',delete=False) as f:

            if isinstance(image, str):

                yield f.name, realpath(normpath(normcase(image)))

                return

It's working since then.

I will forward this thread and issue to pytesseract. 

Thanks for you help.

anyway report it to pytesseract project, so it can be fixed - otherwise next update will bring it once again.
