Selenium + Python: empty output

Question

I installed selenium python for both 3 and 2.7 I run the following script:

1) vi test.py:

from selenium import webdriver
import time


chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=chrome_options)

driver.get('https://python.org')

I get nothing from the output. If I remove the parameters and leave it basic:

2) vi new.py:

from selenium import webdriver
import time


chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=chrome_options)

element = driver.get('https://python.org')

I get the following error:

Traceback (most recent call last):
  File "new.py", line 8, in <module>
    driver = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=chrome_options)

  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

I installed: snap install chromium sudo apt-get install chromium-browser chromium-chromedriver pip install selenium

@inrob try only this, `from selenium import webdriver driver = webdriver.Chrome("/usr/bin/chromedriver"); driver.get("https://www.google.co.in/search?q=stackoverflow")`. don't pass empty options also — Ali, Jan 30 '19 at 09:30

It's normal do not see the driver (automated browser) during the headless mode.
Try to install Chrome browser (your second script):

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome-stable_current_amd64.deb

Hope it helps you!

@inrob, check, please, my updated answer. – Ratmir Asanov Jan 30 '19 at 09:37
sudo dpkg -i google-chrome-stable_current_amd64.deb OUTPUTS: dpkg: error: cannot access archive 'google-chrome-stable_current_amd64.deb': No such file or directory – inrob Jan 30 '19 at 10:09
You need to download first the .deb-package. See my updated answer. Thanks. – Ratmir Asanov Jan 30 '19 at 11:10
How is going? Did you try my last update? – Ratmir Asanov Jan 30 '19 at 13:08
Hi. this:https://pastebin.com/raw/qsxnmdkq Doesnt work. Neither does this https://pastebin.com/raw/Qhx10upU but this works: https://pastebin.com/raw/S707uKFv Any ideas? Also are you available for consulting? – inrob Jan 30 '19 at 13:44
Did it fix your problem? Is it a virtual machine with Ubuntu? – Ratmir Asanov Jan 30 '19 at 13:48
Ubuntu 18.04, testing machine, if you want I can give login details to check. At least the last example works. I needed one working example.However when I connect with vnc it shows gray screen – inrob Jan 30 '19 at 13:52
So, you do not have a monitor for this machine? In this case, it will work only in headless mode (when your browser physically is not visible). If my answer is fixed your asked above problem -- you can accept my answer (check a tick near my answer). Thanks. – Ratmir Asanov Jan 30 '19 at 13:56
I mean monitor as the physical display. – Ratmir Asanov Jan 30 '19 at 14:06
Nope, just a vultr vps is all I have. I used to do it before, the same way – inrob Jan 30 '19 at 14:23
@inrob, in this case, you can run only in headless mode. – Ratmir Asanov Jan 30 '19 at 14:34
