megengine.random.RNG.permutation¶

RNG.permutation(n, *, dtype='int32')[源代码]¶

Generates a random permutation of integers from \(0\) to \(n - 1\).

参数

n (int) – the upper bound. Must be larger than 0.
dtype (str) – the output data type. int32, int16 and float32 are supported. Default: int32

返回

the output tensor.

实际案例

import megengine as mge
import megengine.random as rand

x = rand.permutation(n=10, dtype="int32")
print(x.numpy())

x = rand.permutation(n=10, dtype="float32")
print(x.numpy())

Outputs:

[4 5 0 7 3 8 6 1 9 2]
[3. 4. 9. 0. 6. 8. 7. 1. 5. 2.]
