# BNNSDataLayout7DFirstMajor

A constant that represents a 7D first-major tensor.

## Declaration

```swift
var BNNSDataLayout7DFirstMajor: BNNSDataLayout { get }
```

## Discussion

Discussion The value (i, j, k, l, m, n, o) is at index: o * stride[0] + n * stride[1] + m * stride[2] + l * stride[3] + k * stride[4] + j * stride[5] + i * stride[6]. size[0] is the size of the first dimension (i). size[1] is the size of the second dimension (j). size[2] is the size of the third dimension (k). size[3] is the size of the fourth dimension (l). size[4] is the size of the fifth dimension (m). size[5] is the size of the sixth dimension (n). size[6] is the size of the seventh dimension (o).
