Flask don't know where are your templates.

I use this:

WEBDIR = os.path.dirname(os.path.abspath('__files__'))
PAGESDIR = os.path.join(os.path.dirname(WEBDIR), 'somewhere/templates')
STATICDIR = os.path.join(os.path.dirname(WEBDIR), 'somewhere/static')
...

app = Flask(__name__, template_folder=PAGESDIR, static_folder=STATICDIR)
...
