You could try a webdriver wait for that input before actually searching it. Often that is the main cause for an unexpected "unable to locate element". But the first thing i would try is follow it (not in background) and see if a popup is between login and the main page. For example when i logged in, i got a page asking for a phone number not the main page, which would break the code.
Also please post the traceback in BBcode tags "error", not a screenshot. It helps us be able to copy and paste it.
