Flask Template Not found [duplicate]

By default, Flask looks in the templates folder in the root level of your app.

http://flask.pocoo.org/docs/0.10/api/

template_folder – the folder that contains the templates that should
be used by the application. Defaults to ‘templates’ folder in the root
path of the application.

So you have some options,

1. rename template to templates

2. supply a template_folder param to have your template folder recognised by the flask app:

   app = Flask(__name__, template_folder="template")
