mxnet.np.random.shuffle

shuffle(x)

Modify a sequence in-place by shuffling its contents.

This function only shuffles the array along the first axis of a multi-dimensional array. The order of sub-arrays is changed but their contents remain the same.

Parameters

x (ndarray) – The array or list to be shuffled.

Examples

>>> arr = np.arange(10)
>>> np.random.shuffle(arr)
>>> arr
array([5., 1., 0., 6., 7., 3., 9., 8., 4., 2.])  # random

Multi-dimensional arrays are only shuffled along the first axis:

>>> arr = np.arange(9).reshape((3, 3))
>>> np.random.shuffle(arr)
>>> arr
array([[6., 7., 8.], # random
       [3., 4., 5.],
       [0., 1., 2.]])
