Si analizamos los registros, parece que el problema principal está en el start os.path.basename(self.path) y el mensaje de error posterior selenium.common.exceptions.WebDriverException: Message: ''chromedriver'' executable needs to be in PATH .

Entonces, está claro por el error que el cliente Python no pudo localizar el binario chromedriver .

Tienes que ocuparte de un par de puntos aquí:

1. chrome_options.binary_location : el parámetro configura el chrome.exe no el chromedriver.exe
2. os.path.abspath("chromedriver") recogerá la ruta del archivo de chromedriver pero no chromedriver.exe al final.

3. Aquí está el código de muestra en mi Windows 8 para iniciar Chrome en Headless Mode :

   from selenium import webdriver  
   from selenium.webdriver.chrome.options import Options 
   
   chrome_options = Options()  
   chrome_options.add_argument("--headless")  
   driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r''C:/Utility/BrowserDrivers/chromedriver.exe'')  
   driver.get("http://www.duo.com") 
   print("Chrome Browser Initialized in Headless Mode")
   driver.quit()
   print("Driver Exited")
