I am using a script daily. It's a headless chrome that just checks a site every 5 minutes and suddenly devmode turned on and i can't seem to turn it off. This is my script:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('headless')
driver = webdriver.Chrome + 'E:\Chrome Downloads\chromedriver_win32\chromedriver.exe', chrome_options=options)
And the output is:
[0926/111600.894:ERROR:devtools_http_handler.cc(786)]
DevTools listening on 127.0.0.1:12107
[0926/111601.685:ERROR:browser_gpu_channel_host_factory.cc(103)] Failed to launch GPU process.
It also spews out the F12 developer console info everytime it connects to a new site. :c
I managed to fix it finally :D
options.add_argument('--log-level=3')
That was all it took.
I was running into the same issue and adding the log-level argument only did not work for me.
On Windows you obviously need to add the following option to your ChromeOptions as well:
options.add_experimental_option('excludeSwitches', ['enable-logging'])
As described here: https://bugs.chromium.org/p/chromedriver/issues/detail?id=2907#c3

I am using selenium and python in order to scrape data on a website.
The problem is I need to manually log in because there is a CAPTCHA after the login.
My question is the following : is there a way to start the program on a page that is already loaded ? (for example, here I would log to the website, solve the CAPTCHA manually, and then launch the program that would scrape the data)
Note: I have already been looking for an answer on SO but did not find it, might have missed it as it seems to be an obvious question.
don't open in headless mode. open in head mode.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import time
options = Options()
options.headless = False # Set false here
driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get("http://google.com/")
print ("Headless Chrome Initialized")
time.sleep(30) # wait 30 seconds, this should give enough time to manually do the capture
# do other code here
driver.quit()
I have been using Selenium and python to web scrape for a couple of weeks now. It has been working fairly good. Been running on a macOS and windows 7. However all the sudden the headless web driver has stopped working. I have been using chromedriver with the following settings:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless")
options.add_argument('--no-sandbox')
options.add_argument('--disable-gpu')
chrome_options.add_argument("--window-size=1920x1080")
driver = webdriver.Chrome(chrome_options=options)
driver.get('url')
Initially I had to add the window, gpu and sandbox arguments to get it work and it did work up until now. However, when running the script now it gets stuck at driver.get('url'). It doesn't produce an error or anything just seems to run indefinitely. When I run without headless and simply run:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('url')
it works exactly as intended. This problem is also isolated to my windows machine. Where do I start?
Solved
For some reason the proxy setting was slowing it down. Therefore it got solved by adding:
options.add_argument(f'--proxy-server={None}')
I had exactly the same problem. It appeared randomly after the script has run fine for weeks. OP has led me to the right direction, but his solution doesnt worked for me. I had to add:
chrome_options.add_argument("--no-proxy-server")
chrome_options.add_argument("--proxy-server='direct://'");
chrome_options.add_argument("--proxy-bypass-list=*");
My complete code:
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--start-maximized")
chrome_options.add_argument("--start-fullscreen")
chrome_options.add_argument("--no-proxy-server")
chrome_options.add_argument("--proxy-server='direct://'");
chrome_options.add_argument("--proxy-bypass-list=*");
chrome_options.binary_location = "C:\Program Files (x86)\Google\Chrome Dev\\Application\chrome.exe"
browser = webdriver.Chrome(options=chrome_options)
browser.set_window_size(2000, 1080)

How can Selenium Chrome WebDriver notifications be handled in Python?
Have tried to dismiss/accept alert and active element but seems notifications have to be treated other way. Also, all the Google search results are driving me to Java solution which I do not really need. I'm a newbie in Python.
Thanks in advance.
You can disable the browser notifications, using chrome options.
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)
In December, 2021, using ChromeDriver Version: 96, the python code structure would look like below to handle the ChromeDriver/ Browser notification:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
# Creating Instance
option = Options()
# Working with the 'add_argument' Method to modify Driver Default Notification
option.add_argument('--disable-notifications')
# Passing Driver path alongside with Driver modified Options
browser = webdriver.Chrome(executable_path= your_chrome_driver_path, chrome_options= option)
# Do your stuff and quit your driver/ browser
browser.get('https://www.google.com')
browser.quit()
The answer above from Dec '16 didn't work for me in August 2020. Both Selenium and Chrome have changed, I believe.
I'm using the binary for Chrome 84, which is listed as the current version, even though there's a binary for Chrome 85 available from selenium.dev. I have to presume that's a beta since I have no other info on that.
I only have a partial answer so far, but I believe the following two lines are in the right direction. They're as far as I've gotten tonight. I have a test window that I've opened to Facebook and have the exact window shown in the Question. The code given in pythonjar's answer from Dec 30 '16 above produced error messages for me. These code lines worked without error, so I believe this is the right track.
>>> from selenium.webdriver import ChromeOptions
>>> chrome_options = ChromeOptions()
I'll update this tomorrow, if I get time to work on it.
Sorry for the partial answer. I hope to complete it soon. I hope this helps. If you get there first, please let me know.
Using Chrome Versão 85.0.4183.83 (Versão oficial) 64 bits and ChromeDriver 85.0.4183.83
Here is the code and it is working:
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("https://www.google.com/")

Follow the below code for handling the notification settings with Python selenium
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
option = Options()
option.add_argument("--disable-infobars")
option.add_argument("start-maximized")
option.add_argument("--disable-extensions")
option.add_experimental_option("prefs",
{"profile.default_content_setting_values.notifications": 2
})
Note 1-to allow notification, 2- to block notification
Running latest version of all features
(chrome version 66, selenium version 3.12, chromedriver version 2.39, python version 3.6.5)
I have tried all of the solutions that I have found online but nothing seems to be working. I have automated something using Selenium for Chrome and it does exactly what I need it to do.
The last thing I need to to is hide the browser because I do not need to see the UI. I have attempted to make the browser headless using the following code but when I do the program crashes.
I have also tried to alter the window size to 0x0 and even tried the command: options.set_headless(headless=True) instead but nothing seems to work.
NOTE: I am running on Windows and have also tried with the command:
options.add_argument('--disable-gpu')
Try to move browser over the monitor
driver = webdriver.Chrome()
driver.set_window_position(-2000,0) # if -20000 don't help put -10000
What is happening when you run, does it produce any error or just run as if you hadn't even added the headless argument?
Here's what I do for mine to run headlessly -
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
selenium_chrome_driver_path = "blah blah my path is here"
my_driver = webdriver.Chrome(chrome_options = options, executable_path = selenium_chrome_driver_path)
I'm running this code with python 3.6 with up to date selenium drivers on Windows 8 (unfortunately)
Got the solutions after combining a few sources. It seems that the libraries get often updated and eventually it becomes deprecated. Atm this one worked for me in Windows, using Python 3.4:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.headless = True
driver = webdriver.Chrome(executable_path="C:/Users/Admin/Documents/chromedriver_win32/chromedriver", options=options)
Try to use user agent in chrome_options
ua = UserAgent()
userAgent = ua.random
print(userAgent)
chrome_options.add_argument('user-agent={userAgent}')
I am currently trying to code a basic smartmirror for my coding II class in high school with python. One thing I'm trying to do is open new tabs in full screen (using chrome). I currently have it so I can open url's, but I am not getting them in full screen. Any ideas on code I can use to open chrome in full screen?
If you're using selenium, just code like below:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://google.com')
driver.maximize_window()
As suggested, selenium is a good way to accomplish your task.
In order to have it full-screen and not only maximized I would use:
chrome_options.add_argument("--start-fullscreen");
or
chrome_options.add_argument("--kiosk");
First option emulates the F11 pressure and you can exit pressing F11. The second one turns your chrome in "kiosk" mode and you can exit pressing ALT+F4.
Other interesting flags are:
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
Those will remove the top bar exposed by the chrome driver saying it is a dev chrome version.
The complete script is:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
# chrome_options.add_argument("--start-fullscreen");
chrome_options.add_argument("--kiosk");
driver = webdriver.Chrome(executable_path=rel("path/to/chromedriver"),
chrome_options=chrome_options)
driver.get('https://www.google.com')
"path/to/chromedriver" should point to the chrome driver compatible with your chrome version downloaded from here
