mindspore.ops.normal

mindspore.ops.normal(shape, mean, stddev, seed=None)[source]

Generates random numbers according to the Normal (or Gaussian) random number distribution.

Parameters

shape (tuple) – The shape of random tensor to be generated.
mean (Tensor) – The mean μ distribution parameter, which specifies the location of the peak, with data type in [int8, int16, int32, int64, float16, float32].
stddev (Tensor) – The deviation σ distribution parameter. It should be greater than 0, with data type in [int8, int16, int32, int64, float16, float32].
seed (int) – Seed is used as entropy source for the Random number engines to generate pseudo-random numbers. must be non-negative. Default: None, which will be treated as 0.

Returns

Tensor. The shape should be equal to the broadcasted shape between the input shape and shapes of mean and stddev. The dtype is float32.

Supported Platforms:: Ascend GPU CPU

Examples

>>> shape = (3, 1, 2)
>>> mean = Tensor(np.array([[3, 4], [5, 6]]), mstype.float32)
>>> stddev = Tensor(1.0, mstype.float32)
>>> output = C.normal(shape, mean, stddev, seed=5)
>>> result = output.shape
>>> print(result)
(3, 2, 2)
