mindspore.Tensor.resize

Tensor.resize(*new_shape)[source]

Changes shape and size of tensor in-place.

If the shape of the new tensor is larger than the shape of the original tensor, the new tensor will be filled with 0. And if the shape of the new tensor is smaller than the shape of the original tensor, the new tensor is filled with the elements of the original tensor in order.

Warning

Non-backward-compatible change after version 2.9.0: parameter name new_shape will be renamed to sizes.

Note

Instead of changing the size of the input tensor and returning nothing as in numpy, this method returns a new Tensor with the input size. Numpy argument refcheck is not supported.

Parameters: new_shape (Union[int, tuple(int)]) – Shape of resized tensor.
Returns: Tensor.

Examples

>>> import numpy as np
>>> from mindspore import Tensor
>>> x = Tensor(np.array([[1, 2, 3], [4, 5, 6]], dtype=np.float32))
>>> y = x.resize(3, 3)
>>> print(y)
[[1. 2. 3.]
[4. 5. 6.]
[0. 0. 0.]]
>>> y = x.resize(2, 2)
>>> print(y)
[[1. 2.]
[3. 4.]]
