mindspore.Tensor.copy_

Tensor.copy_(src, non_blocking=False) → Tensor[source]

Copies the elements from src into self tensor and returns self.

Warning

This is an experimental API that is subject to change or deletion.

If Copying is performed between Ascend and Ascend, the src tensor must be broadcastable with the self tensor, and they can be of different data types. Copying is performed between CPU and Ascend or CPU and CPU are only supported if self and src have the same shape and data type and they are all contiguous.

Parameters

src (Tensor) – the source tensor to copy from.
non_blocking (bool, optional) – If True and copying is performed between CPU and Ascend, and self and src have the same shape and data type and are contiguous. The copy may occur asynchronously with respect to the host. For other cases, this argument has no effect. Default: False.

Returns

Return self Tensor.

Supported Platforms:: Ascend

Examples

>>> import numpy as np
>>> from mindspore import Tensor
>>> a = Tensor(np.ones((3, 3)).astype("float32"))
>>> b = Tensor(np.zeros((3, 3)).astype("float32"))
>>> a.copy_(b)
>>> print(a)
