How to Deploy AI models? Part 6- Deploying Web-application on Streamlit via Github | by RAVI SHEKHAR TIWARI | Mar, 2021

Predictors: Pixel value in form of vector with length 64, where each piel value ranges between 0–16

Target : Digit labelled from 0–10

Dataset Shape: 1797 * 65 metrics

1.3. Model

For training the model we followed the following procedure:

Data Split up: 8:2 i.e. 80% training set and 20% for the test set

Model: Support Vector Machine Classifier

Below is the code for the training the model.

import sklearnimport 
sklearn.datasetsimport sklearn.ensemble
import sklearn.model_selection
from sklearn import svm, metrics
import pickle
import os#load datadata = data=sklearn.datasets.load_digits() #Split the data into test andtraintrain_data, test_data, train_labels, test_labels = sklearn.model_selection.train_test_split(data.data, data.target, train_size=0.80)print(train_data,train_labels)#Train a model using random 
model = svm.SVC(kernel=parameters['kernal'],tol=float(parameters['Tol']),max_iter=int(parameters['Max_Iteration'])).fit(X_train,y_train)#test the model
result = model.score(test_data, test_labels)
print(result)#save the model 
filename = ‘iris_model.pkl’
pickle.dump(model, open(filename, ‘wb’))

1.4. Frontend using Streamlit

For feeding the value in the trained model we need some User Interface to accept the data from the user and feed into the trained neural network for classification. As we have seen in the section in 1.2 Dataset where we have 64 vectors for each samples with 10 classes .

4. Top Data Science Platforms in 2021 Other than Kaggle

We will use streamlit API to create the frontend and for displaying the various frontend part of this application. Instead of creating the separate the html files for the front end file streamlit API gives us the flexibility to write the code in the same script which is shown below (as refrence):

import streamlit as st
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import sklearn.datasets
from sklearn.model_selection import train_test_splitcol1, col2= st.beta_columns(2)
with col1:    
st.write("**Profile :** https://www.rstiwari.com")
with col2:   
st.write("**Blog :** https://tiwari11-rst.medium.com/") # Text/Titlest.title("Logistic Regression - Mnist Dataset")        }

Similarly you can create the various frontend elements for reference please refer to the Link. This article does not covers the concept of how to use streamlit for developing the model — It covers how we can deploy the model on streamlit.

1.5. Extracting Packages and their respective versions

We need to create the require.txt file which contains the name of package we used in our application along with their respective version. The process of extracting the requirement.txt file is explained in the Article: Deep Learning/Machine Learning Libraries — An overview.

For this application below is the requirement.txt file content.

streamlit==0.76.0 
joblib==1.0.0 
numpy==1.19.3 
scikit-learn==0.23.2 
scipy==1.5.4 
sklearn==0.0

2. Streamlit

Streamlit is gaining popularity in Machine learning and Data Science. It is a very easy library to create a perfect dashboard by spending a little amount of time. It also comes with the inbuilt webserver and lets you deploy in the docker container.

Step 1:

Open the Link and do the following:

Click on the New app and select Deploy from existing repo option as shown in below image.

Step 2:

Select the Repository

The branch of the repository where the files are present main or master and the name of the script file as shown in below image:

Congratulation!!! we have successfully deployed an Iris classifier web application.

4. Deployed Web Application

The overview of the deployed web application with Iris Application: Link is shown below.

We have reached to an end to the model deployment series, hope you al have gained something from this series. Please visit this link to get list of all deployed application.

As we say “Car is useless if it doesn’t have a good engine” similarly student is useless without proper guidance and motivation. I will like to thank my Guru as well as my Idol “Dr. P. Supraja”- guided me throughout the journey, from the bottom of my heart. As a Guru, she has lighted the best available path for me, motivated me whenever I encountered failure or roadblock- without her support and motivation this was an impossible task for me.
