My script I have been writing has been working great. I just added the option so it would open a profile on chrome using this code.

options = webdriver.ChromeOptions
browser = webdriver.Chrome(executable_path=r"C:\Users\princess\AppData\Local\Programs\Python\Python36-32\chromedriver.exe", chrome_options=options)
options.add_argument(r'user-data-dir=C:\Users\princess\AppData\Local\Google\Chrome\User Data')
options.add_argument('--profile-directory=Profile 1')

When used, I get this error code. 

C:\Users\Princess\Desktop>CHBO.py
Traceback (most recent call last):
  File "C:\Users\Princess\Desktop\CHBO.py", line 12, in <module>
    browser = webdriver.Chrome(executable_path=r"C:\Users\princess\AppData\Local\Programs\Python\Python36-32\chromedriver.exe", chrome_options=options)
  File "C:\Users\Princess\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 59, in __init__
    desired_capabilities = options.to_capabilities()
TypeError: to_capabilities() missing 1 required positional argument: 'self'

How can I fix this?

To create and open a new Chrome Profile you need to follow the following steps :

  • Open Chrome browser, click on the Side Menu and click on Settings on which the url chrome://settings/ opens up.
  • In People section, click on Manage other people on which a popup comes up.
  • Click on ADD PERSON, provide the person name, select an icon, keep the item Create a desktop shortcut for this user checked and click on ADD button.
  • Your new profile gets created.
  • Snapshot of a new profile SeLeNiUm

SeLeNiUm

  • Now a desktop icon will be created as SeLeNiUm - Chrome
  • From the properties of the desktop icon SeLeNiUm - Chrome get the name of the profile directory. e.g. --profile-directory="Profile 2"

profile-directory

  • Get the absolute path of the profile-directory in your system as follows :

    C:\\Users\\Otaku_Wiz\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2

  • Now pass the value of profile-directory through an instance of Options with add_argument() method along with key user-data-dir as follows :

    from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")

  • Execute your Test

  • Observe Chrome gets initialized with the Chrome Profile as SeLeNiUm

SeLeNiUm

What should I do with this part?
C:\\Users\\Otaku_Wiz\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2
Windows! Yikes! If you're looking for the profile and on Linux, go to /home/{user}/.config/google-chrome. For me, it created a "Profile 1". If you're on Mac, go to Users/<user>/Library/Application Support/Google/Chrome (so I'm told)
This has nothing to do with what he asked

You can use options = Options() or options = webdriver.ChromeOptions() at place of options = webdriver.ChromeOptions

Otherwise you are pointing at an object (namely webdriver.ChromeOptions), and not making an instance of that object by including the needed parenthesis

it did open a browser with the profile I wanted but didn't open the sites and navigate as the code is written. I got this back in CMD
:ERROR:cache_util.cc(134)] Unable to move cache folder C:\Users\princess\AppData\Local\Google\Chrome\User Data\ShaderCache\GPUCache to C:\Users\princess\AppData\Local\Google\Chrome\User Data\ShaderCache\old_GPUCache_000 [30224:11480:0314/012119.198:ERROR:disk_cache.cc(169)] Unable to create cache [30224ERROR:shader_disk_cache.cc(601)] Shader Cache Creation failed: -2 [30224:11480:0314/012119.342:ERROR:browser_gpu_channel_host_factory.cc(120)] Failed to launch GPU process. Created new window in existing browser session.
Then it says this:
raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed
@OtakuWiz this is the answer to your question. the answer to your new question is this part of the error message Created new window in existing browser session. You have to close Chrome before running your python code. see here
