Without further ado, let's get straight to the code!
import numpy as np array = ([0, 0]) for i in range(10): array = ((array, [i+1, i+1])) print(array) # [[ 0 0] # [ 1 1] # [ 2 2] # [ 3 3] # [ 4 4] # [ 5 5] # [ 6 6] # [ 7 7] # [ 8 8] # [ 9 9] # [10 10]] rand_arr = ([0]) (rand_arr) print(array[rand_arr[0:5]]) # [[9 9] # [4 4] # [1 1] # [5 5] # [8 8]] (rand_arr) print(array[rand_arr[0:5]]) # [[10 10] # [ 3 3] # [ 4 4] # [ 8 8] # [ 5 5]]
Above this Python implementation to randomly take a matrix array of a few rows is all that I have shared with you, I hope to be able to give you a reference, and I hope you will support me more.
