In this chapter, we will understand the process involved in setting up a project to perform logistic regression in Python, in detail.

Installing Jupyter

We will be using Jupyter – one of the most widely used platforms for machine learning. If you do not have Jupyter installed on your machine, download it from here. For installation, you can follow the instructions on their site to install the platform. As the site suggests, you may prefer to use Anaconda Distribution which comes along with Python and many commonly used Python packages for scientific computing and data science. This will alleviate the need for installing these packages individually.

After the successful installation of Jupyter, start a new project, your screen at this stage would look like the following ready to accept your code.

Now, change the name of the project from Untitled1 to “Logistic Regression” by clicking the title name and editing it.

First, we will be importing several Python packages that we will need in our code.

Importing Python Packages

For this purpose, type or cut-and-paste the following code in the code editor −

In [1]: # import statements
   import pandas as pd
   import numpy as np
   import matplotlib.pyplot as plt

   from sklearn import preprocessing
   from sklearn.linear_model import LogisticRegression
   from sklearn.model_selection import train_test_split

Your Notebook should look like the following at this stage −

Run the code by clicking on the Run button. If no errors are generated, you have successfully installed Jupyter and are now ready for the rest of the development.

The first three import statements import pandas, numpy and matplotlib.pyplot packages in our project. The next three statements import the specified modules from sklearn.

Our next task is to download the data required for our project. We will learn this in the next chapter.
