mindspore.Tensor.unbind

Tensor.unbind(dim=0) → Tensor

Unbind the tensor dimension in specified axis.

Given self tensor of shape \((n_1, n_2, ..., n_R)\) and unbinding it in the specified dim, multiple tensors with shape \((n_1, n_2, ..., n_{dim}, n_{dim+2}, ..., n_R)\) are returned.

Parameters

dim (int, optional) – Dimension along which to unbind. The range is [-R, R). Default: 0 .

Returns

A tuple of tensors, the shape of each objects is the same.

Raises

• TypeError – If dim is not an int.

• ValueError – If dim is out of the range [-R, R).

Supported Platforms:

Ascend GPU CPU

Examples

>>> import numpy as np
>>> from mindspore import Tensor
>>> input = Tensor(np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]))
>>> output = input.unbind(dim=0)
>>> print(output)
(Tensor(shape=[3], dtype=Int64, value=[1, 2, 3]), Tensor(shape=[3], dtype=Int64, value=[4, 5, 6]),
Tensor(shape=[3], dtype=Int64, value=[7, 8, 9]))
