I have a simple Selenium Grid remote driver initialization which is failing with an WebDriverException as below:
from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
selenium_grid_url='http://localhost:4444/wd/hub'
caps = webdriver.DesiredCapabilities.FIREFOX.copy()
caps['platform']="WINDOWS"
caps['version']="8.1"
remotedriver = webdriver.Remote(desired_capabilities=caps,
command_executor=selenium_grid_url)
I get the following error:

Process finished with exit code 1
Is something wrong with my invocation?
EDIT:
Selenium standalone server version: 3.4.0
Java version 1.8.0 (121)
Both hub and node of the grid on the same machine.
Python version 3.5.2
