arrayfire.random module — ArrayFire Python documentation

Random engine class and functions to generate random numbers.

class arrayfire.random.Random_Engine(engine_type=<RANDOM_ENGINE.PHILOX_4X32_10: 100>, seed=0, engine=None)[source]¶

Bases: object

Class to handle random number generator engines.

Parameters

engine_typeoptional: RANDOME_ENGINE. default: RANDOM_ENGINE.PHILOX

• Specifies the type of random engine to be created. Can be one of:

• RANDOM_ENGINE.PHILOX_4X32_10

• RANDOM_ENGINE.THREEFRY_2X32_16

• RANDOM_ENGINE.MERSENNE_GP11213

• RANDOM_ENGINE.PHILOX (same as RANDOM_ENGINE.PHILOX_4X32_10)

• RANDOM_ENGINE.THREEFRY (same as RANDOM_ENGINE.THREEFRY_2X32_16)

• RANDOM_ENGINE.DEFAULT

• Not used if engine is not None

seedoptional int. default: 0

• Specifies the seed for the random engine

• Not used if engine is not None

engineoptional ctypes.c_void_p. default: None.

• Used a handle created by the C api to create the Random_Engine.

Methods

get_seed()

Get the seed for the random engine.

get_type()

Get the type of the random engine.

set_seed(seed)

Set the seed for the random engine.

set_type(engine_type)

Set the type of the random engine.

get_seed()[source]¶

Get the seed for the random engine.

get_type()[source]¶

Get the type of the random engine.

set_seed(seed)[source]¶

Set the seed for the random engine.

set_type(engine_type)[source]¶

Set the type of the random engine.

arrayfire.random.get_default_random_engine()[source]¶

Get the default random engine

Returns

The default random engine used by randu and randn

arrayfire.random.get_seed()[source]¶

Get the seed for the random number generator.

Returns

seed: int.

Seed for the random number generator

arrayfire.random.randn(d0, d1=None, d2=None, d3=None, dtype=<Dtype.f32: 0>, engine=None)[source]¶

Create a multi dimensional array containing values from a normal distribution.

Parameters

d0int.

Length of first dimension.

d1optional: int. default: None.

Length of second dimension.

d2optional: int. default: None.

Length of third dimension.

d3optional: int. default: None.

Length of fourth dimension.

dtypeoptional: af.Dtype. default: af.Dtype.f32.

Data type of the array.

engineoptional: Random_Engine. default: None.

If engine is None, uses a default engine created by arrayfire.

Returns

outaf.Array

Multi dimensional array whose elements are sampled from a normal distribution with mean 0 and sigma of 1. - If d1 is None, out is 1D of size (d0,). - If d1 is not None and d2 is None, out is 2D of size (d0, d1). - If d1 and d2 are not None and d3 is None, out is 3D of size (d0, d1, d2). - If d1, d2, d3 are all not None, out is 4D of size (d0, d1, d2, d3).

arrayfire.random.randu(d0, d1=None, d2=None, d3=None, dtype=<Dtype.f32: 0>, engine=None)[source]¶

Create a multi dimensional array containing values from a uniform distribution.

Parameters

d0int.

Length of first dimension.

d1optional: int. default: None.

Length of second dimension.

d2optional: int. default: None.

Length of third dimension.

d3optional: int. default: None.

Length of fourth dimension.

dtypeoptional: af.Dtype. default: af.Dtype.f32.

Data type of the array.

engineoptional: Random_Engine. default: None.

If engine is None, uses a default engine created by arrayfire.

Returns

outaf.Array

Multi dimensional array whose elements are sampled uniformly between [0, 1]. - If d1 is None, out is 1D of size (d0,). - If d1 is not None and d2 is None, out is 2D of size (d0, d1). - If d1 and d2 are not None and d3 is None, out is 3D of size (d0, d1, d2). - If d1, d2, d3 are all not None, out is 4D of size (d0, d1, d2, d3).

arrayfire.random.set_default_random_engine_type(engine_type)[source]¶

• RANDOM_ENGINE.PHILOX (same as RANDOM_ENGINE.PHILOX_4X32_10)

• RANDOM_ENGINE.THREEFRY (same as RANDOM_ENGINE.THREEFRY_2X32_16)

• RANDOM_ENGINE.DEFAULT

arrayfire.random.set_seed(seed=0)[source]¶

Set the seed for the random number generator.

Parameters

seed: int.

Seed for the random number generator
