My code:
from pytractor import webdriver
driver = webdriver.Firefox()
driver.get('http://gratisal.matcao.vn/')

I got this error:
File "C:\Python27\lib\site-packages\pytractor\mixins.py", line 221, in get
' {}'.format(full_url, message)
pytractor.exceptions.AngularNotFoundException: Message: Angular could not be found on page: http://gratisal.matcao.vn/: retries looking for angular exceeded

The page i try to get into driver is an angular 1.5 app, Is there something i don't know to get the webdriver work
