# sum(axes:keepDimensions:)

Adds a sum reduction operation along the given axis operation to the current graph.

## Declaration

```swift
func sum(axes: [Int], keepDimensions: Bool) -> BNNSGraph.Builder.Tensor<T>
```

## Parameters

- `axes`: The axes over which the operation computes the sum.
- `keepDimensions`: A Boolean value that specifies that the operation keeps the reduced dimension with a size of 1.
