AttributeError: 'module' object has no attribute 'youtube'

Question

My python function

def get_youtube_client():
    client = gdata.youtube.service.YouTubeService()
    client.client_id = "xxxxxxxx"
    client.developer_key = get_api_key()
    return client

I have used third-party vendoring to introduce gdata into the libs folder.

I am getting the following error when I execute get_youtube_client
