How to run selenium chromedriver as root? (not working even with --no-sandbox

Question

I'm trying to run chromedriver to create some selenium tests. I followed this manual to install it. I'm trying to run this code:

from selenium import webdriver
driver = webdriver.Chrome(chrome_options=options)

When I call this python script as normal user, it's working. But when I call it as root (it is necessary for me), it's not working. I've tried to follow some advices and I was trying to use several Google chrome options, e.g.:

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

options = Options()
options.add_argument('--no-sandbox')

driver = webdriver.Chrome(chrome_options=options,
                          service_args=[
                              '--verbose',
                              '--log-path=/home/me/Projects/selenium.log'
                          ]
)

But it's still not working and here is a part of log:

The strange is, that in the InitSession command there is --no-sandbox argument, but when the Chrome is launched, it's not. The error Running as root without --no-sandbox is not supported. shows up instead.

Any advice please?

Solution

The problem was in chromedriver version. I used version 2.26. After reinstallation to current version (2.35), it starts to work. So, there is only one mandatory argument --no-sandbox and everything is working now. Thank you again.
