selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start with Selenium and Chrome on RaspberryPi

Question

I created some really trivial script to just open browser with specific URL it looks like this:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome()
driver.get("http://www.python.org")

Once I execute this with command python /path/to/file.py I get an error:

Traceback (most recent call last):
  File "/home/pi/tmp/test.py", line 4, in <module>
    driver = webdriver.Chrome()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/chrome/webdriver.py", line 75, in __init__
    desired_capabilities=desired_capabilities)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 156, in __init__
    self.start_session(capabilities, browser_profile)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 251, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 320, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (chrome not reachable)
  (The process started from chrome location /usr/bin/chromium is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver=2.40,platform=Linux 4.14.69-v7+ armv7l)

It seems like I run out of memory or idk. Any idea what could be wrong?

Check the browser version and chromedriver version compatibility. Chromedriver devs like to indicate incompatibility by crashing the whole world instead of an error message... Here you can find which chromedriver supports which chrome browser. (As a side note I'm surprised that there is a chromedriver binary for rpi/arm) — skandigraun

This error message...

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (chrome not reachable)
  (The process started from chrome location /usr/bin/chromium is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver=2.40,platform=Linux 4.14.69-v7+ armv7l)

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

The version information of the Selenium Client and Chrome would have helped us to analyze your issue. However as per the discussions:

Your main issue seems to be incompatibility between the version of the binaries you are using as follows:

You are using chromedriver=2.40
Release Notes of chromedriver=2.40 clearly mentions the following :

Supports Chrome v66-68

The current release version of Chrome is v69.0

If you are using Chrome v69.0 there is a mismatch between ChromeDriver v2.40 and the Chrome Browser v69.0

Solution

Upgrade ChromeDriver to current ChromeDriver v2.42 level.
Keep Chrome version between Chrome v68-70 levels. (as per ChromeDriver v2.42 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
