# batchSizePerSequenceStep

The batch size for each sequence.

## Declaration

```swift
var batchSizePerSequenceStep: [Int]? { get }
```

## Discussion

Discussion The framework only populates this value when sequenceLengths is valid. The length of this array is equal to the maximum sequence length in sequenceLengths; that is, sequenceLengths[0] when sortedSequences is true.
