Why driver.get doesn't work in Python Selenium when using Profile

What I need
I need to run Selenium with Chrome Profile
Here is my code:
from selenium import webdriver
import time
options = webdriver.ChromeOptions()
options.add_argument("--user-data-dir=/home/atom/.config/google-chrome") #Path to your chrome profile
options.add_argument('--profile-directory=Profile 1')
driver = webdriver.Chrome(options=options)
driver.get('https://youtube.com')
time.sleep(5)
Problem
The code opens Google Chrome instead of Chromedriver. Profile is loaded. But driver.get doesn't work
Question
How can I use Selenium with Chrome profile?

What chromedriver does is briefly described here. When you call get on the webdriver, you are asking for the site to be opened on the chrome browser. If you want to use brave browser or another browser implementation using the chromium engine, you may specify the location of the browser's binary using:
ChromeOptions options = new ChromeOptions();
options.setBinary("/path/to/other/chrome/binary");
You may load a specific profile by using:
ChromeOptions options = new ChromeOptions();
options.addArguments("user-data-dir=/path/to/your/custom/profile");
Specifying no profile (not including this option should load the default profile).
A complete list of supported options may be found here.

How can open my local Chrome (no chromedriver.exe) and navigate with Selenium

I am stucking with a script to do the following
I want to open my local chrome in which I have several accounts logged in, so for this I do:
from selenium import webdriver
driver = webdriver.Chrome(executable_path="C:/Program Files (x86)/Google/Chrome/Application/chrome.exe")
but when I do that
driver.get(url)
doesn't send me to the URL I want.
On the other hand if I do it with
driver = webdriver.Chrome()
driver.get(URL)
Everything goes smoothly but it opens it with the chromedriver.exe and therefore the accounts are not logged in.
Any idea how to open the local chrome and then be able to browse?
Any solutions for the problem

You need to load your user profile while initializing selenium webdriver.
You can do it using
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Path to local user profile") #Path to your chrome profile
w = webdriver.Chrome(executable_path="C:\\Path to your local chrome.exe installation", chrome_options=options)
Typing chrome://version/ in chrome address bar will show you the path to user profile.

In automation, when we use Selenium to interact with a web browser, we need a browser driver to communicate with the specific browser. ChromeDriver is the specific driver for Google Chrome. When you use webdriver.Chrome(), it launches the Chrome browser using the ChromeDriver executable. Chromedriver is a bridge between your Selenium script and the Chrome browser exactly as taxi driver is a bridge between you and taxi car.
Chrome uses profiles. By default in tests are not used local profiles of users. The new temporary profile is created instead. However, it is possible to point out the profile which should be used.

You need to pass additional argument user-data-dir to the Chrome options when initialising the Chrome driver, in order to open the local default Chrome profile. If you need to point out specific profile then you should use profile-directory.
Example:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument(r"--user-data-dir=C:/Users/[username]/AppData/Local/Google/Chrome/User Data")
options.add_argument(r'--profile-directory=YourProfileDir')
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get(URL)
To find the profile folder on Windows right-click the desktop shortcut of the Chrome profile you want to use and go to properties -> shortcut and you will find it in the "target" text box.

Selenium Grid: install chrome extensions on session

I need to use one chrome extension from Chrome Store in my test on Selenium Grid in Chrome browser, but I have some troubles :(
I tried to go to extension URL in browser (https://chrome.google.com/webstore/detail/...) and press key Install, but I can't confirm install in popup browser window
I tried to download crx extension file, but then i open it in browser I saw confirm windows and do not understand how to confirm installation
I tried to use this method - https://developer.chrome.com/extensions/external_extensions add JSON file and run browser - don't work, but I try it on Mac, not Linux
webdriver.remote can use only FireFox options (seleniumhq.github.io/selenium/docs/api/py/webdriver_remote/selenium.webdriver.remote.webdriver.html)
If I use Selenium Grid I can't change Chrome browser start settings, can't add any keys :(
Maybe you know another method to install the extension on Selenium Grid browser session?

You can use ChromeOptions.
ChromeOptions options = new ChromeOptions();
options.addExtensions(new File("/path/to/extension.crx"));
ChromeDriver driver = new ChromeDriver(options);
Alternatively, you can add the options to an already existing DesiredCapabilities object.
// Add ChromeDriver-specific capabilities through ChromeOptions.
ChromeOptions options = new ChromeOptions();
options.addExtensions(new File("/path/to/extension.crx"));
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
ChromeDriver driver = new ChromeDriver(capabilities);
You could also use a remote web driver:
DesiredCapabilities capability = DesiredCapabilities.chrome();
// above code goes here...
WebDriver driver = new RemoteWebDriver(new URL(hubUrl), capability);

how to close chrome browser popup dialog using selenium webdriver and python

I have a python code that uses selenium webdriver (along with chromedriver), to log into facebook and take a screenshot of the page.
the script itself works as expected, however, after logging in, chrome browser shows a dialog regarding facebook notifications (Chrome Popup)
The dialog seems to be generated by the browser, not the page itself.
i'm unable to identify and capture the element or use "switch to alert" method.
How can i interact with this dialog (either Allow, Dismiss or close it)?
Thanks!

in Python you can use
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--disable-notifications")
webdriver.Chrome(os.path.join(path, 'chromedriver'),
chrome_options=chrome_options)

You can try with launching the chrome browser with disabled pop-ups (browser pop-ups). The following code snippet is in Java. It will be somewhat similar in python i believe.
ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-popup-blocking");
options.addArguments("test-type");
ChromeDriver driver = new ChromeDriver(options);

Python selenium how to load the browser's data(cookies or bookmarks)

When using selenium to open a web page, it automatically deletes all cookies u had saved in browser which is inconvenient.
Find solution in this page java solution
but don't know how to solve the problem using Python.

Point the browser to a profile file (that's what the java example in the given link is doing)
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('user-data-dir=<path to chrome profile>')
browser = webdriver.Chrome(chrome_options=chrome_options)
On Linux the <path to chrome profile> is /home/<user>/.config/google-chrome.
