mindspore.ops.rand

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

Returns a new tensor that fills numbers from the uniform distribution over an interval $[0,1)$ based on the given shape and dtype.

Warning

The Ascend backend does not support the reproducibility of random numbers, so the seed parameter has no effect.

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 applied. 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 random numbers from the uniform distribution on the interval $[0,1)$.

Raises

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

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

Supported Platforms:

Ascend GPU CPU

Examples

>>> from mindspore import ops
>>> print(ops.rand((2,3)))
