# batchSizePerSequenceStep

The batch size for each sequence.

## Declaration

```occ
@property (nonatomic, copy, readonly, nullable) NSArray<NSNumber *> * batchSizePerSequenceStep;
```

## 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’s sequenceLengths[0] when sortedSequences is YES.
