Example usage:

```python
from abc import ABC, abstractmethod
from datasets import load_dataset
from PIL import Image
from typing import Iterator

class DatasetInterface(ABC):
    @abstractmethod
    def get_generator(self) -> Iterator[tuple[Image.Image, list[float], list[float], list[str]]]:
        pass

class CocoDataset(DatasetInterface):
    def __init__(self):
        self.dataset = load_dataset("detection-datasets/coco", split="val", streaming=True)

    def get_generator(self) -> Iterator[tuple[Image.Image, list[float], list[float], list[str]]]:
        for elem in self.dataset:
            image = elem['image'].convert("RGB")
            boxes = elem['objects']['bbox']
            probs = [1.0] * len(boxes) # max confidence
            labels = elem['objects']['category']
            yield image, boxes, probs, labels
