Pyhton Appium Cannot Remote Emulator

I was try running manual appium is work to open my emulator in appium inspector, and then i try create simple script. here is my script :

from appium import webdriver
import time

desired_capabilities = {}

desired_capabilities['appPackage'] = 'com.facebook.lite'
desired_capabilities['appActivity'] = 'com.facebook.lite.MainActivity'
desired_capabilities['platformName'] = 'Android'
desired_capabilities['deviceName'] = 'VirtualDevice'
desired_capabilities['udid'] = 'emulator-5554'

driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub/', desired_capabilities)

but after run the script show this error :

Traceback (most recent call last):

    driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub/', desired_capabilities)

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: The requested resource could not be found, or a request was received using an HTTP method that is not supported by the mapped resource

>Solution :

Not sure, but from your logs, try to remove the last / from wd/hub/.

driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_capabilities)
