## ScatterElementsUpdate <a name="ScatterElementsUpdate"></a> {#openvino_docs_ops_movement_ScatterElementsUpdate_3}
|
|
|
|
**Versioned name**: *ScatterElementsUpdate-3*
|
|
|
|
**Category**: Data movement operations
|
|
|
|
**Short description**: Creates a copy of the first input tensor with updated elements specified with second and third input tensors.
|
|
|
|
**Detailed description**: For each entry in `updates`, the target index in `data` is obtained by combining the corresponding entry in
|
|
`indices` with the index of the entry itself: the index-value for dimension equal to `axis` is obtained from the value of the corresponding entry in
|
|
`indices` and the index-value for dimension not equal to `axis` is obtained from the index of the entry itself.
|
|
|
|
For instance, in a 3D tensor case, the update corresponding to the `[i][j][k]` entry is performed as below:
|
|
|
|
```
|
|
output[indices[i][j][k]][j][k] = updates[i][j][k] if axis = 0,
|
|
output[i][indices[i][j][k]][k] = updates[i][j][k] if axis = 1,
|
|
output[i][j][indices[i][j][k]] = updates[i][j][k] if axis = 2
|
|
```
|
|
|
|
`update` tensor dimensions are less or equal to the corresponding `data` tensor dimensions.
|
|
|
|
**Attributes**: *ScatterElementsUpdate* does not have attributes.
|
|
|
|
**Inputs**:
|
|
|
|
* **1**: `data` tensor of arbitrary rank `r` and of type *T*. Required.
|
|
|
|
* **2**: `indices` tensor with indices of type *T_IND*. The rank of the tensor is equal to the rank of `data` tensor.
|
|
All index values are expected to be within bounds `[0, s - 1]` along axis of size `s`. If multiple indices point to the
|
|
same output location then the order of updating the values is undefined. If an index points to non-existing output
|
|
tensor element or is negative then exception is raised. Required.
|
|
|
|
* **3**: `updates` tensor of shape equal to the shape of `indices` tensor and of type *T*. Required.
|
|
|
|
* **4**: `axis` tensor with scalar or 1D tensor with one element of type *T_AXIS* specifying axis for scatter.
|
|
The value can be in range `[-r, r - 1]` where `r` is the rank of `data`. Required.
|
|
|
|
**Outputs**:
|
|
|
|
* **1**: tensor with shape equal to `data` tensor of the type *T*.
|
|
|
|
**Types**
|
|
|
|
* *T*: any numeric type.
|
|
|
|
* *T_IND*: any integer numeric type.
|
|
|
|
* *T_AXIS*: any integer numeric type.
