I can't use chromedriver

HI, I don’t know why, but I can’t use chromedriver.

I put chromedriver in the config folder of my project and added the following configuration code, but I only get an error message.

I’ve been suffering so much with this setting for days now. please help

code:
class AndroidDriverSetup(unittest.TestCase):
desired_caps = {
‘platformName’: ‘Android’,
‘automationName’: ‘UiAutomator2’,
‘appium:autoGrantPermissions’: ‘true’,
‘appium:appPackage’: ‘com.android.beta’,
‘appium:appActivity’: ‘com.android.ui.activity.SplashActivity’,
‘noReset’: True,
‘chromedriverExecutable’: ‘/config/chromedriver’
}

last_screen = None

def setUp(self) -> None:
    package_name = self.driver.current_package
    print(package_name)
    if "beta" in package_name:
        self.driver.get('pref://beta?FRAME_LIMIT=b/true')

Error message:
