Hey @sachinrastogi23101997, there is no library named visualize, its actually a .py file. You can get it here,

prateek27/deep-neural-network/blob/master/visualize.py

import matplotlib.pyplot as plt
import numpy as np

def plot_decision_boundary(model, X, y,cmap=plt.cm.jet):
    """
    Given a model(a function) and a set of points(X), corresponding labels(y), scatter the points in X with color coding
    according to y. Also use the model to predict the label at grid points to get the region for each label, and thus the 
    descion boundary.
    Example usage:
    say we have a function predict(x,other params) which makes 0/1 prediction for point x and we want to plot
    train set then call as:
    plot_decision_boundary(lambda x:predict(x,other params),X_train,Y_train)
    params(3): 
        model : a function which expectes the point to make 0/1 label prediction
        X : a (mx2) numpy array with the points
        y : a (mx1) numpy array with labels
    outputs(None)
    """
    # Set min and max values and give it some padding
    x_min, x_max = X[:, 0].min() - 1, X[:, 0].max() + 1

Save in the same folder where your ipynb is and is trying to import functions from visualize.py.

Hope this resolved your doubt.
Plz mark the doubt as resolved in my doubts section.
