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)
