Converted EXE file size is too large

[Rajasekaran]

I have converted the python script to exe format using the below command, but the exe file size is too large. So when executing the exe file, it is taking a long time to start the execution. Could you please help us to solve this issue. Thanks in Advance.

pyinstaller.exe --onefile tiff-2-txt.py

Script File Size: 1.90 KB
Converted EXE file size: 153 MB

Python = 3.8
Pyinstaller Version = 5.8.0

import os.path
import cv2
import pytesseract



'''
- language will be defined in "lang.ini" file in the same path of input files.
- language code should be three digit iso code, multiple language should be add by separation of "+" symbol. e.g.: eng+hin
- Tesseract version 5 should be installed in "C:\Program Files\Tesseract-OCR"
