I am trying to create a webcrawler using Selenium, but I get this error when I try to create the webdriver object.
selenium.common.exceptions.SessionNotCreatedEx
You can find the older versions of chrome driver here.
I dont think it is a good idea to install chrome from sources other than the official channel and installation of the same can cause issues. See if the google update service is running in your PC. This will automatically update the chrome version to latest. Mine is running Version 71.0.3578.98 (Official Build) (64-bit).
