I was having the same problem on centos7.1 because I was the root user, and it was resolved after adding the code chrome_options.add_argument('--no-sandbox')
here is my code
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('https://www.google.com/')
print driver.current_url
driver.quit()
