`tesseract_get_version` returns cached result after version change

The @run_once decorator on pytesseract.tesseract_get_version() means that if the version is switched via

pytesseract.pytesseract.tesseract_cmd = 'tesseract5'

for example, after pytesseract.tesseract_get_version() has been called, it no longer returns correct results.

As a complete example:

import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'Tesseract/tesseract4'
print(pytesseract.get_tesseract_version())
pytesseract.pytesseract.tesseract_cmd = 'Tesseract/tesseract5'
print(pytesseract.get_tesseract_version())

gives the following (even though I have switched from version 4 to version 5)

4.1.3

Apart from the fact that Windows usually has a different package management, yes. All downloads/installers seem to be unofficial though in this case: https://tesseract-ocr.github.io/tessdoc/Downloads.html

DISTRIB_ID=Ubuntu DISTRIB_RELEASE=18.04 It actually is. Thanks, I’ll look for it.

btw, Is it the same procedure for windows to update to tesseract 5.0.0 though?
