Given the information as follows:
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
solve:
Download chromedriver, on the specified path, and add the path to the path environment variable (Properties - Advanced System Settings - Advanced - Environment Variables)
Download: https://sites.google.com/a/chromium.org/chromedriver/downloads
PS: Note view your chrome version, you need to download the version with chrome consistent chromedriver
否则会报错：selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version XX
