Deploying the machine learning model in Heroku using Flask

Creating an API with Heroku is Simple one , you can do it very quickly.

Now we are going to create an API for sentiment analysis , you can also alternate the code any machine learning model

I created a folder name as sentiment_analysis

At minimum level your file should contain these .

we will get those one by one

this is an simple flask app for giving the result the text is positive or negative or neutral , just save this and run the app.py

then open the jupyter or python editor and another side this server to be running parallel .

The main thing you have to keep in mind that we have to send the data in json format .

In this we just converted the data into json format

After that i just requested the running server with its address and passing the data with it.

We got answer as positive . It is working , Now we have to deploy this to Heroku.

Create a new account in Heroku if you did not have it

After Creating the account Click on new.

Click the Create new app

Then install the Heroku-CLI in your system

For Ubuntu 16+ sudo snap install –classic heroku

For Mac brew tap heroku/brew && brew install heroku

Ok now we are ready to deploy but we need create two more files in it

Procfile [P has to be in caps]

you can create the requirements.txt by this command

pip freeze > requirements.txt

We are ready to deploy it ,This is how our folder finally looks like

Then do the below steps in your cmd

$ heroku login

the it will popup the login in access in browser click login to it

$ cd sentiment_analysis/
$ git init
$ heroku git:remote -a sentimentsts

Deploy your application

Commit your code to the repository and deploy it to Heroku using Git.

$ git add .
$ git commit -am "make it better"
$ git push heroku master

Everything is done, Click the open app in your app page , you will get the link of the API

Finallyyyyy..
