[🐛 Bug]: Python Selenium 4.12.0 cannot create Chromium driver on raspberry Pi/PiOS "AttributeError: 'str' object has no attribute 'capabilities'"

[CalebKierum]

What happened?

When trying to get Chromium going with selenium I constantly get the following error

chromedriver
Traceback (most recent call last):
  File "/home/admin/.local/lib/python3.9/site-packages/selenium/webdriver/common/driver_finder.py", line 38, in get_path
    path = SeleniumManager().driver_location(options) if path is None else path
  File "/home/admin/.local/lib/python3.9/site-packages/selenium/webdriver/common/selenium_manager.py", line 76, in driver_location
    browser = options.capabilities["browserName"]
AttributeError: 'str' object has no attribute 'capabilities'

How I have tried getting it

print(webdriver.Chrome())
print(webdriver.Chrome("/usr/bin/chromedriver"))
print(webdriver.Chrome('/usr/lib/chromium-browser/chromedriver'))

Browser version

chromium-browser --version
Chromium 113.0.5672.95 Built on Raspbian , running on Raspbian 11

Webdriver version

sudo apt install chromium-chromedriver

Selenium

Type "help", "copyright", "credits" or "license" for more information.
>>> import selenium
>>> selenium.__version__
'4.12.0'

Yet as you can see I have the chromium browser, I have the chromium driver, their versions match. Why isn't this working well? What does this error mean?

I have tried reading other posts to figure this one out but most of them seemed to have the issue that the driver version did not match. This is not the case here. Furthermore in the documentation for selenium it says that in version 4.6 or higher it should automatically download drivers.
What might be going on here?

How can we reproduce the issue?

Set up a raspberryPi running RaspberryPiOS

sudo apt-get install chromium-browser
sudo apt install chromium-chromedriver

Then in python try running any of the following
print(webdriver.Chrome())
print(webdriver.Chrome("/usr/bin/chromedriver"))
print(webdriver.Chrome('/usr/lib/chromium-browser/chromedriver'))

Notice them not working

For Raspberry Pi architecture you need to provide the location of the custom driver. The way you are doing it is no longer supported.

The proper way to provide the location of the driver now is to use a service class: https://www.selenium.dev/documentation/webdriver/drivers/service/#driver-location

[CalebKierum]

AH! For future people reading this here is what I needed

service = webdriver.ChromeService(executable_path = '/usr/bin/chromedriver')
driver = webdriver.Chrome(service=service)

Appreciate the speedy response
