If we analyze the logs it seems the main issue is with in start os.path.basename(self.path) and subsequent error message:

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH

So it’s clear from the error that the Python client was unable to locate the chromedriver executable binary.

You need to take care of a couple of things as follows:

chrome_options.binary_location : The parameter points to the chrome.exe not the chromedriver.exe
os.path.abspath("chromedriver") will pick up the file path of chromedriver but won’t append chromedriver.exe at the end.

Here is the sample code on my windows-8 system to start google-chrome-headless:

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:UtilityBrowserDriverschromedriver.exe')  
driver.get("http://www.duo.com") 
print("Chrome Browser Initialized in Headless Mode")
driver.quit()
print("Driver Exited")
