mindspore.mint.ones

mindspore.mint.ones(size, *, dtype=None)

Creates a tensor filled with value ones.

Creates a tensor with shape described by the first argument and fills it with value ones in type of the second argument.

Parameters

size (Union[tuple[int], list[int], int, Tensor]) – The specified shape of output tensor. Only positive integer or tuple or Tensor containing positive integers are allowed. If it is a Tensor, it must be a 0-D or 1-D Tensor with int32 or int64 dtypes.

Keyword Arguments

dtype (mindspore.dtype, optional) – The specified type of output tensor. If dtype is None , mindspore.float32 will be used. Default: None .

Returns

Tensor, whose dtype and size are defined by input.

Raises

TypeError – If size is neither an int nor an tuple/list/Tensor of int.
