This function takes a batch size and any number of iterables, then yields batches of elements from those iterables. All input iterables must have the same length. Args: batch_size (int): Size of each batch to yield. *args (Any): Variable length input iterables to batch. All iterables must have the same length. Yields: (list[Any]): A list of batched elements from each input iterable.

The stability score is the IoU between binary masks obtained by thresholding the predicted mask logits at high and low values. Args: masks (torch.Tensor): Batch of predicted mask logits. mask_threshold (float): Threshold value for creating binary masks. threshold_offset (float): Offset applied to the threshold for creating high and low binary masks. Returns: (torch.Tensor): Stability scores for each mask in the batch.
