randperm¶

paddle. randperm ( n, dtype='int64', name=None ) [source]

Returns a 1-D Tensor filled with random permutation values from 0 to n-1, with dtype.

Parameters

• n (int) – The upper bound (exclusive), and it should be greater than 0.

• dtype (str|np.dtype, optional) – The data type of the output Tensor. Supported data types: int32, int64, float32, float64. Default is int64.

• name (str, optional) – The default value is None. Normally there is no need for user to set this property. For more information, please refer to Name.

Returns

A 1-D Tensor filled with random permutation values from 0 to n-1, with dtype.

Return type

Tensor

Examples

import paddle

out1 = paddle.randperm(5)
# [4, 1, 2, 3, 0]  # random

out2 = paddle.randperm(7, 'int32')
# [1, 6, 2, 0, 4, 3, 5]  # random
