遥感图像数据集RSICD

Question

下面这段代码来自：
https://github.com/isaaccorley/torchrs#remote-sensing-image-captioning-dataset-rsicd
整个功能是怎样的，最终能生成字幕嘛？

import torchvision.transforms as T
from torchrs.datasets import RSICD

transform = T.Compose([T.ToTensor()])

dataset = RSICD(
    root="path/to/dataset/",
    split="train",  # or 'val', 'test'
    transform=transform
)

x = dataset[0]
"""
x: dict(
    x:        (3, 224, 224)
    captions: List[str]
)
"""
