To Reproduce
import ocrmypdf
import os
input_file='nachtrag.pdf'
output_file='out_'+input_file
in_path=os.path.join(r"C:\Users\fkhalil\primeStone\docrecog\sampleDocs",input_file)
out_path=os.path.join(r"C:\Users\fkhalil\primeStone\docrecog\sampleDocs",output_file)
ocrmypdf.ocr(in_path,out_path,language='deu')
System:
- python version 3.8
- windows 10
- pdf created from MS words with scanned pictures
Sample file
Sorry, I can't help with this. I really don't know anything about cx_freeze or how to use it. I suggest going to the cx_Freeze support forums for guidance. ocrmypdf is a worst case scenario for packaging in that it uses multiprocessing, threads, subprocesses, signals, and C library calls.
If you want to make a pull request to facilitate executable packaging I would generally be interested.
Its old but i had the same problem. The solution for me was:
if __name__ == '__main__':
#your code#
