shuffle numpy array code example
Example 1: randomly shuffle array python
import random
l = list(range(5))
print(l)
lr = random.sample(l, len(l))
print(lr)
print(l)
Example 2: numpy randomly swap lines
>>> X = np.random.random((6, 2))
>>> X
array([[ 0.9818058 , 0.67513579],
[ 0.82312674, 0.82768118],
[ 0.29468324, 0.59305925],
[ 0.25731731, 0.16676408],
[ 0.27402974, 0.55215778],
[ 0.44323485, 0.78779887]])
>>> np.random.shuffle(X)
>>> X
array([[ 0.9818058 , 0.67513579],
[ 0.44323485, 0.78779887],
[ 0.82312674, 0.82768118],
[ 0.29468324, 0.59305925],
[ 0.25731731, 0.16676408],
