mindspore.ops.SparseGatherV2
- class mindspore.ops.SparseGatherV2[source]
Returns a slice of input tensor based on the specified indices and axis.
- Inputs:
input_params (Tensor) - The shape of tensor is \((x_1, x_2, ..., x_R)\).
input_indices (Tensor) - The shape of tensor is \((y_1, y_2, ..., y_S)\). Specifies the indices of elements of the original Tensor, must be in the range [0, input_param.shape[axis]).
axis (int) - Specifies the dimension index to gather indices.
- Outputs:
Tensor, the shape of tensor is \((z_1, z_2, ..., z_N)\).
- Raises
TypeError – If axis is not an int.
- Supported Platforms:
Ascend
GPU
Examples
>>> input_params = Tensor(np.array([[1, 2, 7, 42], [3, 4, 54, 22], [2, 2, 55, 3]]), mindspore.float32) >>> input_indices = Tensor(np.array([1, 2]), mindspore.int32) >>> axis = 1 >>> out = ops.SparseGatherV2()(input_params, input_indices, axis) >>> print(out) [[2. 7.] [4. 54.] [2. 55.]]
