Q:

Unable to load unpacked extension into chrome using Selenium webdriver

I am new to using web driver but I have followed what was mentioned here (How can I launch Chrome with an unpacked extension?)  and all that I could get from other web search. 
I am trying to test an extension for chrome which I have developed but I haven't been able to figure out how to start chrome with extension loaded on it.  Here is what I have till now and I would appreciate if someone could tell me the issue with the code (I was successful in launching Chrome using webdriver):
import time 

from selenium import webdriver

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

browser = webdriver. Chrome() browser.get('http://seleniumhq.org/')

ChromeOptions options = new ChromeOptions();

options.addArguments("load-extension=C:\Users\mave\Desktop\Browser_Extension_Feature\extension_v5");

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities.setCapability(ChromeOptions. CAPABILITY, options);

ChromeDriver driver = new ChromeDriver(capabilities);

time.sleep(15)

browser.quit()

A:

I was finally able to figure out how to run an unpacked extension and would leave this code for anyone who has similar troubles in future:
import time

from selenium import webdriver

from selenium.webdriver.chrome.options import Options

chrome_options = Options()

chrome_options.add_argument("load-extension=C:\Users\mave\Desktop\Browser_Extension_Feature\extension_v5");

browser = webdriver. Chrome(chrome_options=chrome_options)

browser.get('http://www.seleniumhq.org/')

time.sleep(5)

browser.quit()
