If token_indices contains no True values, torch.where(token_indices)[0] will be an empty tensor. Accessing [0] on this empty tensor will raise an IndexError. Consider checking for this case and raising a more informative ValueError.

found_indices = torch.where(token_indices)[0]
if not found_indices.numel():
    raise ValueError("IMAGE_TOKEN_INDEX not found in input_ids, cannot perform DivPrune.")
pruning_paras['image_token_start_index'] = found_indices[0].item()
