Health-Care-Platform

Health Care Platform is project aiming to provide an online health-care system using machine learning.

Based on the NHANES dataset we are going to create a ML model that predict if the client will eventually:

• Risk Having Diabetes.
• Will likely experience a stroke.

Run this project

Sign up for Heroku

Heroku, being a Software as a Service (SaaS)-type of service, requires you to create an account and login before you can start using its computers. Don't worry, creating an account and running a simple app is free and doesn't require a credit card.

You can create an account at this URL: https://signup.heroku.com/dc

Download the Heroku toolbelt

Heroku has a command-line "toolbelt" that we must download and install in order commands that will simplify our communication with the Heroku servers. The toolbelt can be downloaded at: https://toolbelt.heroku.com/

Authenticate with Heroku with heroku login

Installing the Heroku toolbelt will give you access to the heroku command which has several subcommands for interacting with the Heroku service.

The first command you need to run is heroku login, which will ask you to enter your login credentials so that every subsequent heroku command knows who you are:

(You will only have to do this once)

$ heroku login

Let's create a Flask app

Creating a Flask app form scratch

Create a basic Flask app of any kind, i.e. one that consists of just app.py. You can revisit the lessons here or the sample repo at: https://github.com/datademofun/heroku-basic-flask

Heck, try to write it out by memory if you can -- below, I've made the app output simple HTML that includes the current time and a placeholder image from the loremflickr.com service:

from flask import Flask
from datetime import datetime
app = Flask(__name__)

@app.route('/')
def homepage():
    the_time = datetime.now().strftime("%A, %d %b %Y %l:%M %p")

    return """
    <h1>Hello heroku</h1>
    <p>It is currently {time}.</p>

    <img src="http://loremflickr.com/600/400">
    """.format(time=the_time)

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

You should be able to run this app on your own system via the familiar invocation and visiting http://localhost:5000:

$ python app.py

Fork your Repository

You should fork your repository and then clone it so you can manage your own repo and use this only as a template.

$ git clone https://github.com/your_username/flask-heroku-example.git

At this point you should be able to modify the Flask app app.py:

"""Flask App Project."""

from flask import Flask, jsonify
app = Flask(__name__)


@app.route('/')
def index():
    """Return homepage."""
    json_data = {'Hello': 'World!'}
    return jsonify(json_data)


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

WARNING: If you change the file name (app.py) and the Flask app (app = Flask(__name__)) then remember to change Heroku's Procfile:

web: gunicorn <filename>:<app_name>

Create Your Heroku App

You can also leave your_app_name empty if you want Heroku to create a randomized name.

$ heroku create your_app_name
Creating app... done, ⬢ your_app_name
https://your_app_name.herokuapp.com/ | https://git.heroku.com/your_app_name.git

Deploy Your Project

Your project is going to be deploy using gunicorn as a web server using the Procfile and it will be detected as a Python project since it is declared in runtime.txt

• Add necessary files and commit them

$ git add -A
$ git commit -am "finished flask project"

• Push to Heroku

$ git push heroku master

That's it, you can visit your app now with heroku open.
