import the selenium and chrome.option to let chrom run in headlessmode

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

if you use chrome or chromiun as root user on linux you should add "--no-sandbox" option and set windows size to avoid some item no show because the window size is too small

chrome_options = Options()
chrome_options.add_argument("--headless") # headless mode
chrome_options.add_argument("--no-sandbox") # run as root user should add --no-sandbox option
chrome_options.add_argument("--window-size=1920x1080")

you can download the chrome driver from http://chromedriver.storage.googleapis.com the last version is 2.38

chrome_driver = "path to chromedriver"
# start the driver 
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=chrome_driver)
driver.get("https://www.google.com")

The error says it all :

File "<stdin>", line 1, in <module>

Seems the error occurs on the very first line which is as :

driver=webdriver.Chrome()

This is because here in this code block unless you import webdriver, the driver object is unable to properly initiate/handle the instance of WebBrowser i.e. Chrome Browser.

Solution :

While working with Selenium 3.x, ChromeDriver 2.33.x you need Chrome Browser v60-62 with Python 3.x bindings, and you have to do the following:

  • Download the chromedriver binary from this link.
  • Import the necessary modules
  • Provide the absolute path of the chromedriver binary in your system.
  • Below is the minimal code :
    //The Linux Example
    from selenium import webdriver
    driver = webdriver.Chrome(executable_path=r'/usr/bin/chromedriver')
    driver.get('https://www.google.co.in')
    print("Page Title is : %s" %driver.title)
    driver.quit()

    //The Windows Example
    from selenium import webdriver
    driver = webdriver.Chrome(executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
    driver.get('https://www.google.co.in')
    print("Page Title is : %s" %driver.title)
    driver.quit()

Update :

On a separate note as you are seeing WebDriverException: Message: unknown error: Chrome failed to start: crashed perform the following additional steps :

  • Uninstall Google Chrome from your system through Revo Uninstaller.
  • Run CCleaner to wipe out all the unwanted OS chores.
  • Take a system Reboot
  • Install latest official build of Google Chrome
  • Execute your Test.

If you're going to use an old version of Chrome - you will need to match the version of chromedriver to it. In your case you are using Chrome 38, which was last officially supported by ChromeDriver 2.13, which you can find here

If your users are using newer versions of Chrome, I would recommend updating your distro and installed chrome to match them.

You are using the current latest chromedriver 2.33 with Google Chrome 38.0.2125.104.

From the release notes, the support for this version is:

----------ChromeDriver v2.33 (2017-10-03)----------
Supports Chrome v60-62

Make sure also that you are using the latest stable version of selenium.

Furthermore, from Help WebDriver find the downloaded ChromeDriver executable, you should do one of these

  1. include the ChromeDriver location in your PATH environment variable
  2. (Python only) include the path to ChromeDriver when instantiating webdriver.Chrome (see sample below)
