cx_Freeze: Executable with pytesseract fails on other PC

问题 I've made an executable file from my Python - OCR program ( import pytesseract ) using cx_Freeze. The resulting .exe works fine on my own machine.

It seems like pytesseract isn't included in the executable / zip-folder. Here is the ErrorLog: The file is not a PNG-file: 20181108 Kontaktanzeigen-Er_sucht_sie.jpg The file is not a PNG

问题 I am using pytesseract, pillow,cv2 to OCR an image and get the text present in the image. Since my input is a scanned PDF document, I first converted it into an image (JPEG) format and then tried extracting the text. I am only half way there. The input is a table and the titles are not being displayed, since the titles have a black background. I also tried getstructuringelement but unable to figure out a way Here is what I did- import cv2 import os import numpy as np import pytesseract

问题 I'm creating a bot for a video game and I have to read some information displayed on the screen. Given that the information is always at the same position, I have no issue to take a screenshot and crop the picture to the right position. 90% of the time, the recognition will be perfect, but sometimes it will return something that seems totally random (see the example below). I've tried to turn the picture into black and white with no success, and tried to change the pytesseract config (config
