What happened?

Trying to run the Selenium Python script using pytest framework. My interpreter is set to python 310 but when running the code the chromedriver.exe version is picked from python 27.

So getting the below warning. How to overcome this issue.

My Selenium version is 4.11.2 and Chrome browser version is 115.0.5790.171

How Selenium Manager looks for the installed drivers?

How can we reproduce the issue?

@pytest.fixture(scope='session')
def driverObject(request):
    global driver
    sys.path.insert(0, os.getcwd())
    browser = option.browser
    if browser in 'firefox':
        driver = webdriver.Firefox()
    else:
        options = webdriver.ChromeOptions()
        options.add_experimental_option('excludeSwitches', ['enable-logging'])
        driver = webdriver.Chrome(options=options)
        driver.get_log('browser')
    driver.maximize_window()
    driver.implicitly_wait(20)
    return driver
def test_valid_login(driverObject):
login(driver, url, clientId, username, password, app)
