mindspore.ops.GatherD
- class mindspore.ops.GatherD[source]
Gathers elements along an axis specified by dim.
Refer to
mindspore.ops.gather_elements()
for more details.- Inputs:
x (Tensor) - The input tensor.
dim (int) - The axis along which to index. It must be int32 or int64.
index (Tensor) - The indices of elements to gather. It can be one of the following data types: int32, int64. The value range of each index element is [-x_rank[dim], x_rank[dim]).
- Outputs:
Tensor, has the same data type with x.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> x = Tensor(np.array([[1, 2], [3, 4]]), mindspore.int32) >>> index = Tensor(np.array([[0, 0], [1, 0]]), mindspore.int32) >>> dim = 1 >>> output = ops.GatherD()(x, dim, index) >>> print(output) [[1 1] [4 3]]
