# index(_:)

Slice the tensor at the specified dimension.

## Declaration

```swift
static func index(_ index: Int) -> any MLTensorRangeExpression
```

## Discussion

Discussion For example: let x = MLTensor(randomNormal: [1, 3, 28, 28], scalarType: Float.self) let y = x[..., 0] // or x[..., .index(0)] y.shape // is [1, 3, 28]
