mindspore.ops.ones
- mindspore.ops.ones(shape, dtype=None)[source]
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
shape (Union[tuple[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.
dtype (
mindspore.dtype
) – The specified type of output tensor. If dtype isNone
, mindspore.float32 will be used. Default:None
.
- Returns
Tensor, has the same type and shape as input shape value.
- Raises
TypeError – If shape is not tuple, int or Tensor.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> import mindspore >>> from mindspore import ops >>> output = ops.ones((2, 2), mindspore.float32) >>> print(output) [[1. 1.] [1. 1.]]
