Randomly shuffle a sparse matrix in python

Question

is there an easy way to shuffle a sparse matrix in python?

This is how I shuffle a non-sparse matrix:

    index = np.arange(np.shape(matrix)[0])
             


        

Answer 1

A better way can be shuffling the index of CSR Matrix and fetching the rows of matrix as such:

from random import shuffle
indices = np.arange(matrix.shape[0]) #gets the number of rows 
shuffle(indices)
shuffled_matrix = matrix[list(indices)]
