mindspore.Generator

class mindspore.Generator

A generator that manages the state of random numbers and provides seed and offset for random functions. When the seed and offset are fixed, the random function generates the same random sequence.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore as ms
>>> from mindspore import Generator
>>> generator = Generator()
>>> generator.manual_seed(5)
>>> print(generator.initial_seed())
5
>>> state = generator.get_state()
>>> generator.seed()
>>> generator.set_state(state)
>>> print(generator.initial_seed())
5

Parameters

seed (int) – Set the generator seed.

Returns

Generator, the generator instance.

seed()

Seed generator with random number.

Returns

Randomly generated seeds, the type is int.

set_state(state)

Parameters

state (tensor) – target state of the generator.
