flask-mongoengine из mongoengine.document import Document, EmbeddedDocument ImportError: невозможно импортировать имя документа

Я хочу использовать приложение для разработки flask-mongoengine, но при запуске приложения появляется importError

Моя фляга run.py 

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from app import app


if __name__ == '__main__':
    app.run(debug=True)

мое приложение init .py 

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from flask import Flask
import flask_mongoengine
from flask_mongoengine import MongoEngine

app = Flask(__name__)

app.config['MONGODB_SETTINGS'] = {
    'db':   'datasync_datax',
    'host': '192.168.100.85',
    'port': 27017
}

db = MongoEngine()
db.init_app(app)

Проблемы при запуске:

ImportError: cannot import name Document

Проблема была решена.

Я обновил свою библиотеку flask-mongoengine! 

sudo pip install --upgrade flask-mongoengine
...
