mindspore.ops.rand_like(input, seed=None, *, dtype=None)[source]

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

  • input (Tensor) – Input Tensor to specify the output shape and its default dtype.

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

Keyword Arguments

dtype (mindspore.dtype, optional) – Designated tensor dtype, it must be float type. If None, the same dtype of input will be applied. Default: None .

Returns

Tensor, with the designated shape and dtype, filled with random numbers from the uniform distribution on the interval \([0, 1)\).

Raises

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

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

Supported Platforms:

Ascend GPU CPU

>>> import mindspore as ms
>>> from mindspore import Tensor, ops
>>> a = Tensor([[2, 3, 4], [1, 2, 3]])
>>> print(ops.rand_like(a, dtype=ms.float32))
