This error message...

SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81

...implies that the ChromeDriver v81 was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser where is version is other then 81.0.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• You mentioned about using chromedriver=80 and chrome=80 but somehow while your program execution ChromeDriver v 81.0 is used.

• So, it's quite evident your have chromedriver=81.0 present within your system and is present within the system PATH variable which gets invoked while you:

  driver = webdriver.Chrome()

Solution

There are two solutions:

• Either you upgrade chrome to Chrome Version 81.0 level. (as per ChromeDriver v81.0 release notes)

• Or you can override the default chromedriver v81.0 binary location with chromedriver v80.0 binary location as follows:

  from selenium import webdriver
  
  driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe')
  driver.get('http://google.com/')
