mindspore.ops.randn

mindspore.ops.randn(*size, dtype=None, seed=None)

Returns a new Tensor with given shape and dtype, filled with a sample (or samples) from the standard normal distribution.

Parameters

size (Union[int, tuple(int), list(int)]) – Shape of the new tensor, e.g., $(2,3)$ or $2$.

Keyword Arguments

• dtype (mindspore.dtype, optional) – Designated tensor dtype, it must be float type. If None, mindspore.float32 will be used. Default: None .

• seed (int, optional) – Random seed, must be greater or equal to 0. Default: None , and 0 will be used.

Returns

Tensor, with the designated shape and dtype, filled with a sample (or samples) from the “standard normal” distribution.

Raises

• TypeError – seed is not a non-negative integer.

• ValueError – If dtype is not a mstype.float_type.

• ValueError – If size contains invalid number.

Supported Platforms:

Ascend GPU CPU
