mindspore.numpy.rand

mindspore.numpy.rand(*shape, dtype=mstype.float32)[源代码]

Returns a new Tensor with given shape and dtype, filled with random numbers from the uniform distribution on the interval $[0, 1)$ .

参数

*shape (Union[int, tuple(int), list(int)]) – Shape of the new tensor, e.g., $(2, 3)$ or $2$ .
dtype (Union[mindspore.dtype, str], optional) – Designated tensor dtype, it must be float type. Default is mindspore.float32.

返回

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

异常

TypeError – If input arguments have types not specified above.
ValueError – If dtype is not float type.

Supported Platforms:: Ascend GPU CPU
