mindspore.Tensor.reshape

Tensor.reshape(*shape)

Rearranges the input Tensor based on the given shape .

The shape can only have one -1 at most, in which case it’s inferred from the remaining dimensions and the number of elements in the input.

Parameters

shape (Union[int, tuple[int], list[int]]) – If shape is a tuple or list, its elements should be integers, and only constant value is allowed. i.e., \((y_1, y_2, ..., y_S)\).

Returns

Tensor, If the given shape does not contain -1, the shape of tensor is \((y_1, y_2, ..., y_S)\). If the k-th position in the given shape is -1, the shape of tensor is \((y_1, ..., y_{k-1}, \frac{\prod_{i=1}^{R}x_{i}}{y_1\times ...\times y_{k-1}\times y_{k+1}\times...\times y_S} , y_{k+1}, ..., y_S)\), in where the shape of input tensor is \((x_1, x_2, ..., x_R)\).

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> input = Tensor(np.array([[-0.1, 0.3, 3.6], [0.4, 0.5, -3.2]]), mindspore.float32)
>>> output = input.reshape(3, 2)
>>> print(output)
[[-0.1  0.3]
 [ 3.6  0.4]
 [ 0.5 -3.2]]
