Selenium undetected chromedriver with different chrome-versions?

I have the following code which works fine on a computer where chrome 122 is installed currently -

import undetected_chromedriver as uc
driver = uc.Chrome()
driver.get('https://ballzy.eu/en/men/sport/shoes')

But when I run this code on a computer where a different chrome-version is installed like 120, I get the following error -

(selenium) C:\DEV\Fiverr\ORDER\stefamn_jan669_jankore_janxx2\Ballzy>python test3.py
Traceback (most recent call last):
  File "C:\DEV\Fiverr\ORDER\stefamn_jan669_jankore_janxx2\Ballzy\test3.py", line 2, in <module>

    self.error_handler.check_response(response)
  File "C:\DEV\.venv\selenium\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 229, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:50596
from session not created: This version of ChromeDriver only supports Chrome version 122
Current browser version is 120.0.6099.200

Is it somehow possible that the correct chromedriver is automatically downloaded?

(when I use the normal selenium driver - I just use the following driver-definition, and it works fine with that on several computers)

srv=Service()
  driver = webdriver.Chrome (service=srv, options=options)

How can i do this also with the undetected chromedriver so it is working on differnt chrome version installations on different computers?

Complementing @Michael Mintz 's approach,here's a possible fix I tried and worked: Automatically set the version_main from the Error log Using a regular Expression as shown in the snippet below:

import re
import undetected_chromedriver as uc
def initialize_session():
        try: 
            sess = uc.Chrome()
        except Exception as e: 
            main_version_string = re.search(r"Current browser version is (\d+\.\d+\.\d+)", str(e)).group(1)
            main_version = int(main_version_string.split(".")[0])
            sess = uc.Chrome(version_main=main_version)
        return sess

With undetected-chromedriver, you have to update the version_main arg of uc.Chrome() if you don't want to use the latest available driver version to match Chrome. Eg:

import undetected_chromedriver as uc

driver = uc.Chrome(version_main=120)

Alternatively, you can use https://github.com/seleniumbase/SeleniumBase with UC Mode, which is basically undetected-chromedriver with some improvements, such as automatically getting a version of chromedriver that is compatible with your version of Chrome. Set uc=True to activate UC Mode in a SeleniumBase script. Here's an example:

from seleniumbase import Driver

driver = Driver(uc=True)

There's some documentation about it here: https://github.com/seleniumbase/SeleniumBase/issues/2213

Here's a larger script:

from seleniumbase import Driver

driver = Driver(uc=True)
driver.get("https://nowsecure.nl/#relax")
# DO MORE STUFF
driver.quit()

For customizing the reconnect time when loading a URL that has bot detection services, you could swap the get() line with something like this:

driver.uc_open_with_reconnect("https://nowsecure.nl/#relax", reconnect_time=5)

(The reconnect_time is the wait time before chromedriver reconnects with Chrome. Before the time is up, a website cannot detect Selenium, but it also means that Selenium can't yet issue commands to Chrome.)

Here is one way:

pip install selenium chromedriver_autoinstaller

In code:

import chromedriver_autoinstaller as chromedriver
chromedriver.install()
dr = webdriver.Chrome()
