WebPython provides the preprocessing library, which contains the normalize function to normalize the data. It takes an array in as an input and normalizes its values between 0 0 and 1 1. It then returns an output array with the same dimensions as the input. from sklearn import preprocessing import numpy as np a = np.random.random ( (1, 4)) a = a*20 WebNow we can use the normalize () method on the array which normalizes data along a row. We can see the command below. arr_norm = preprocessing.normalize ( [arr]) print …
