I am on Mac OS X using selenium with python 3.6.3.
This code runs fine, opens google chrome and chrome stays open.:
chrome_options = Options()
chrome_options.binary_location="../Google Chrome"
chrome_options.add_argument("disable-infobars");
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("http://www.google.com/")
But with the code wrapped inside a function, the browser terminates immediately after opening the page:
def launchBrowser():
chrome_options = Options()
chrome_options.binary_location="../Google Chrome"
chrome_options.add_argument("disable-infobars");
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("http://www.google.com/")
launchBrowser()
I want to use the same code inside a function while keeping the browser open.
Just simply add:
while(True):
pass
To the end of your function. It will be like this:
def launchBrowser():
chrome_options = Options()
chrome_options.binary_location="../Google Chrome"
chrome_options.add_argument("disable-infobars");
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("http://www.google.com/")
while(True):
pass
launchBrowser()
My guess is that the driver gets garbage collected, in C++ the objects inside a function (or class) get destroyed when out of context. Python doesn´t work quite the same way but its a garbage collected language. Objects will be collected once they are no longer referenced.
To solve your problem you could pass the object reference as an argument, or return it.
def launchBrowser():
chrome_options = Options()
chrome_options.binary_location="../Google Chrome"
chrome_options.add_argument("start-maximized");
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("http://www.google.com/")
return driver
driver = launchBrowser()
To make the borwser stay open I am doing this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
def browser_function():
driver_path = "path/to/chromedriver"
chr_options = Options()
chr_options.add_experimental_option("detach", True)
chr_driver = webdriver.Chrome(driver_path, options=chr_options)
chr_driver.get("https://target_website.com")
The browser is automatically disposed once the variable of the driver is out of scope.
So, to avoid quitting the browser, you need to set the instance of the driver on a global variable:
Dim driver As New ChromeDriver
Private Sub Use_Chrome()
driver.Get "https://www.google.com"
' driver.Quit
End Sub
This is somewhat old, but the answers on here didn't solve the issue. A little googling got me here
http://chromedriver.chromium.org/getting-started
The test code here uses sleep to keep the browser open. I'm not sure if there are better options, so I will update this as I learn.
import time
from selenium import webdriver
driver = webdriver.Chrome('/path/to/chromedriver') # Optional argument, if not specified will search path.
driver.get('http://www.google.com/xhtml');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()
My solution is to define the driver in the init function first, then it won't close up the browser even the actional
To whom has the same issue, just set the driver to global, simple as following:
global driver
driver.get("http://www.google.com/")
This resolved the problem on my side, hope this could be helpful
Adding experimental options detach true works here:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option("detach", True)
driver = webdriver.Chrome(options=options)
As per the code block you shared there can be 3 possible solutions as follows :
In the binary_location you have to change the .. to . (. denotes Project Workspace)
In the binary_location you have to change the .. to /myspace/chrome (Absolute Chrome Binary)
While initiating the driver, add the switch executable_path :
driver = webdriver.Chrome(chrome_options=options, executable_path=r'/your_path/chromedriver')
def createSession():
**global driver**
driver = webdriver.Chrome(chrome_driver_path)
driver.maximize_window()
driver.get("https://google.com")
return driver
To prevent this from happening, ensure your driver variable is defined outside your function or as a global variable, to prevent it from being garbage collected immediately after the function completes execution.
In the example above, this could mean something like:
driver = webdriver.Chrome(chrome_options=get_options())
def get_options():
chrome_options = Options()
chrome_options.binary_location="../Google Chrome"
chrome_options.add_argument("disable-infobars")
return chrome_options
def launchBrowser():
driver.get("http://www.google.com/")
launchBrowser()
Hi the below solutions worked for me Please have a try these.
Solution 1 : of Google chrome closes automatically after launching using Selenium Web Driver.
Check the Version of the Chrome Browser driver exe file and google chrome version you are having, if the driver is not compatible then selenium-web driver browser terminates just after selenium-web driver opening, try by matching the driver version according to your chrome version
The reason why the browser closes is because the program ends and the driver variable is garbage collected after the last line of code. For the second code in the post, it doesn't matter whether you use it in a function or in global scope. After the last statement is interpreted, the driver variable is garbage collected and the browser terminates from program termination.
Solutions:
Set chrome options
Use the time module
Use an infinite loop at the end of your program to delay program closure
You can simply add:-
options = webdriver.ChromeOptions()
options.add_experimental_option("detach", True)
driver = webdriver.Chrome(options=options)

When I run the code here, the instagram site should open and stay open, but when I run it, the site closes as soon as it opens. What should I do?
the page closes as soon as it opens
It shouldn't stay open with the code you've provided.
For example:
driver.get("https://instagram.com/%22)
Should be:
driver.get("https://instagram.com/%22")
There is one more thing you should do to make sure it works:
from time import sleep
#your code
#here
sleep(15)
This will make sure the code doesn't stop working after it's done what you wanted it to do for another 15 seconds.
If you want to keep the Chrome Tab alive after code execution. Consider to use Options.
from selenium.webdriver.chrome.options import Options
# Don't Close Chrome
chrome_options = Options()
chrome_options.add_experimental_option("detach", True)
# Initialize Chrome
driver = webdriver.Chrome(options=chrome_options)
I'm using Selenium's webdriver and GeckoDriverManager to open a website and take a screenshot in Firefox. That part works fine. I wanted to specify where to save this screenshot using selenium.webdriver.set_preference() to specify the download path and saving this under an options variable. If I use firefox_driver=webdriver.Firefox(service=service, options=options) the website no longer launches. This is the code I used to set the option preferences: https://stackoverflow.com/a/69974916
Does anyone have an idea where the problem might be coming from?
def load_driver():
service=Service(GeckoDriverManager().install())
options = Options()
options.set_preference("browser.helperApps.alwaysAsk.force", False)
options.set_preference("browser.download.manager.showWhenStarting", False)
options.set_preference("browser.helperApps.neverAsk.openFile", "image/png")
options.set_preference("browser.helperApps.neverAsk.saveToDisk", "image/png")
options.set_preference("browser.download.folderList", 1)
firefox_driver = webdriver.Firefox(service=service) #stops working if I add options=options parameter here
def getscreenshot():
driver = load_driver()
driver.get(website)
sleep(3)
driver.get_screenshot_as_file("screenshot.png")
driver.quit()
print("end...")
I'd like to launch Chrome with its default profile using Python's webdriver so that cookies and site preferences persist across sessions.
How can I do that?
This is what finally got it working for me.
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Path") #Path to your chrome profile
w = webdriver.Chrome(executable_path="C:\\Users\\chromedriver.exe", chrome_options=options)
To find path to your chrome profile data you need to type chrome://version/ into address bar . For ex. mine is displayed as C:\Users\pc\AppData\Local\Google\Chrome\User Data\Default, to use it in the script I had to exclude \Default\ so we end up with only C:\Users\pc\AppData\Local\Google\Chrome\User Data.
Also if you want to have separate profile just for selenium: replace the path with any other path and if it doesn't exist on start up chrome will create new profile and directory for it.
This solved my problem. (remove Default at the end)
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--user-data-dir=/home/username/.config/google-chrome")
cls.driver = webdriver.Chrome(options=options,
executable_path="./../ext/chromedriver")
Chrome_Options ist deprecated. Use options instead
I solved my problem with answer of "Yoannes Geissler".
In my case My profile was named "Profile 2"
My Code :
options = webdriver.ChromeOptions()
options.add_argument('--user-data-dir=C:/Users/GOD/AppData/Local/Google/Chrome/User Data')
options.add_argument('--profile-directory=Profile 2')
wd = webdriver.Chrome(options=options)
The below line solved my problem:
options.add_argument('--profile-directory=Profile 2')
Just to share what worked for me. Using default's profile was complicated, chrome keeps crashing.
from pathlib import Path
from selenium import webdriver
driver_path = Path("{}/driver/chromedriver75.exe".format(PATH_TO_FOLDER))
user_data_dir = Path("{}/driver/User Data".format(PATH_TO_FOLDER))
options = webdriver.ChromeOptions()
# TELL WHERE IS THE DATA DIR
options.add_argument("--user-data-dir={}".format(user_data_dir))
# USE THIS IF YOU NEED TO HAVE MULTIPLE PROFILES
options.add_argument('--profile-directory=Default')
driver = webdriver.Chrome(executable_path=driver_path, options=options)
driver.get("https://google.com/")
By doing this Chrome will create the folder User Data and keep all the data in it where I want and it's easy to just move your project to another machine.
This answer is pretty simple and self-explained.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
exec_path_chrome = "path/to/Google Chrome" #Do not use this path that is extracted from "chrome://version/"
exec_path_driver = "path/to/chromedriver"
ch_options = Options() #Chrome Options
ch_options.add_argument("user-data-dir = /path/to/Chrome Profile") #Extract this path from "chrome://version/"
driver = webdriver.Chrome(executable_path = exec_path_driver, options = ch_options) #Chrome_Options is deprecated. So we use options instead.
driver.get("https://stackoverflow.com/a/57894065/4061346")
As #MadRabbit said type chrome://version/ into the address bar to find the path to your chrome profile data.
It appears like this in Windows C:\Users\pc\AppData\Local\Google\Chrome\User Data\Default
It appears like this in Mac /Users/user/Library/Application Support/Google/Chrome/Default
So all you have to do is to erase the last portion Default from the profile path.
Note: Make sure you don't run more than one session at the same time to avoid problems.
This is what I did.
import chromedriver_binary
chrome_options = Options()
chrome_options.add_experimental_option("detach", True)
chrome_options.add_argument(r"--user-data-dir=User Data Directory")
chrome_options.add_argument(r"--profile-directory=Profile name")
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches",["enable
logging"])
chrome_options.add_experimental_option("excludeSwitches", ["enable
automation"])
chrome_options.add_argument("start-maximized")
self.driver = webdriver.Chrome(chrome_options=chrome_options)
self.wait = WebDriverWait(self.driver, 20)
Here we do not need to give the chrome driver path.
I managed to use a proxy server with selenium for chrome using the code below:
chromedriver = "C:/Seltests/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=141.0.175.141:443')
driver = webdriver.Chrome(chrome_options=chrome_options)
However, I would like to know if it is possible to change that proxy to a new one during run-time. Or if there is any other way of doing this so it allows me to. I'm thinking that using the code above I would have to have the browser close then re-open to start a new session and use another proxy? Please help :)
You will have to re-launch the browser instance in order to achieve this. Wherever you want to change the proxy insert the following code:
driver.quit()
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=<new proxy>')
driver = webdriver.Chrome(chrome_options=chrome_options)
This will close the current browser and launch a new one with the new proxy.
Simple question: how to completely disable logging when using Selenium from Python bindings, ex code as follows:
browser = webdriver.Chrome()
I've tried things like:
options = webdriver.ChromeOptions();
options.add_argument('--log-level 3')
browser = webdriver.Chrome(chrome_options=options)
or even:
options = webdriver.ChromeOptions();
options.add_argument('--disable-logging')
browser = webdriver.Chrome(chrome_options=options)
but still the file 'chromedriver.log' is appearing on each new run of the tests.
You may set options.add_argument("--log-level=3") for Chrome browser to be run with Selenuim, or you may set logging level to some higher level with:
import logging
logger = logging.getLogger('selenium.webdriver.remote.remote_connection')
logger.setLevel(logging.WARNING) # or any variant from ERROR, CRITICAL or NOTSET
But some messages will appear anyway in this case, including the starting DevTools message or SSL handshake error messages.
To run Chrome browser with Selenium in console in completely silent mode, you should use this snippet:
options = Options()
options.headless = True
options.add_experimental_option("excludeSwitches", ["enable-logging"])
That trick will suppress any console message from either the Selenium driver or the browser itself, including the first message DevTools listening on ws://127.0.0.1 at the very start.
At the same time some runtime step-by-step data can be saved to service log file, in case its argument has been added.
driver = webdriver.Chrome(service_log_path='/dev/null')
The source code of Chrome's webdriver, shows the existence of an option called service_log_path.
So if you want to get rid of the file, you could set this property to
/dev/null if you are running under Linux/Unix ;
NUL under windows
Hope it helps
Just example for Windows people:
webdriver.Firefox(log_path='NUL')
Accepted answer is correct, but if you are new to Python / windows like i am, example like this will cut you few hours of google time.
To disable logging using Selenium and Python you need to add an experimental option through an instance of ChromeOptions() as follows:
add_experimental_option('excludeSwitches', ['enable-logging'])
Implementation
selenium4 compatible code
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
options = Options()
options.add_experimental_option('excludeSwitches', ['enable-logging'])
s = Service('C:\\BrowserDrivers\\chromedriver.exe')
driver = webdriver.Chrome(service=s, options=options)
this worked for me:
chrome_options.add_experimental_option('excludeSwitches', ['enable-logging'])
courtesy of:
https://joshuatz.com/posts/2020/selenium-webdriver-disabling-chrome-logging-messages/
if you set service_log_path = None, it won't generate the geckodriver.log file:
driver = webdriver.Firefox(options=options, service_log_path=None)
I know this is old but this is still the first thing that comes up when you search for a way to prevent logging from selenium and it did not get rid of the "dev listening" messages for me and I found a way that does:
ChromeDriverService service = ChromeDriverService.CreateDefaultService();
service.HideCommandPromptWindow = true;
IWebDriver driver = new ChromeDriver(service,options);
